Description

記録装置、記録方法、及び記録制御用のコンピュータプログラムRecording apparatus, recording method, and computer program for recording control
　本発明は、例えば楽曲等の一のコンテンツの再生に合わせて、楽曲等の他のコンテンツを記録する記録装置、記録方法、及び記録制御用のコンピュータプログラムの技術分野に関する。 The present invention relates to a technical field of a recording apparatus, a recording method, and a computer program for recording control that record other contents such as music in accordance with, for example, reproduction of one content such as music.
　演奏者の演奏に合わせて伴奏を開始させると共に、演奏者の演奏の録音を開始する音楽装置が知られている。具体的には、特許文献１に記載されているように、演奏者の演奏が開始する時刻を予測すると共に、当該予測した時刻に合わせて伴奏及び録音を開始させる装置が知られている。この装置は、演奏者が行うカウント操作（アタック）が所定回数を超えて検出された場合に、当該検出時刻からアタックの間隔の平均期間を加えた時刻を、演奏者の演奏が開始する時刻であると予測している。その結果、音楽装置は予測した時刻が到来する前に、伴奏を開始させるための楽曲開始命令及び演奏の録音を開始させるための録音開始命令を発行することができる。従って、自動的に再生が開始される伴奏に合わせて演奏者が行う演奏が録音される。 Music devices that start accompaniment in accordance with the performance of the performer and start recording the performance of the performer are known. Specifically, as described in Patent Document 1, there is known an apparatus that predicts a time at which a player's performance starts and starts accompaniment and recording in accordance with the predicted time. In this apparatus, when a count operation (attack) performed by a player is detected exceeding a predetermined number of times, a time obtained by adding an average period of attack intervals from the detection time is a time at which the player's performance starts. Predict that there is. As a result, the music apparatus can issue a music start command for starting accompaniment and a recording start command for starting recording of the performance before the predicted time arrives. Therefore, the performance performed by the performer is recorded in accordance with the accompaniment that is automatically started to be reproduced.
特開２００９－３００６２２号公報JP 2009-300622 A
　しかしながら、上述した先行技術では、演奏者が行うカウント操作から推定されるＢＰＭ（Beat Per Minute）や当該カウント操作の何拍目ないしは何拍後に演奏者が演奏を開始するかの設定に基づいて予測される時刻に、演奏の録音を開始させている。このため、演奏者のカウント操作の精度が悪かったり又は演奏者が何拍目に演奏を開始するかを適切に設定していなかったりすれば、予測される時刻は、演奏者が演奏を開始する本来の時刻とかけ離れたものとなってしまいかねない。つまり、予測される時刻の精度が相対的に悪化してしまいかねない。従って、適切なタイミングで演奏者の演奏の録音を開始できるとは限らないという技術的な問題点を有している。 However, in the above-described prior art, prediction is made based on the BPM (Beat Per Minute) estimated from the count operation performed by the performer and the setting of how many beats or after what beat the performer starts the performance. The performance recording is started at the scheduled time. For this reason, if the accuracy of the player's counting operation is poor or if the player does not properly set the beat at which the performance starts, the player starts the performance at the predicted time. It could be far from the original time. In other words, the accuracy of the predicted time may be relatively deteriorated. Therefore, there is a technical problem that it is not always possible to start recording the performance of the performer at an appropriate timing.
　尚、このような技術的問題点は、楽曲等を演奏する場合に限らず、任意のコンテンツ（例えば、映像等）の再生に合わせて他のコンテンツを記録する場合においても同様に生じ得る。 It should be noted that such technical problems are not limited to playing music or the like, but may also occur when recording other content in accordance with the reproduction of arbitrary content (for example, video).
　本発明が解決しようとする課題には上記のようなものが一例として挙げられる。本発明は、一のコンテンツデータの再生に合わせて入力される他のコンテンツデータを記録する場合に、当該他のコンテンツデータを好適なタイミングで記録する（或いは、適切なタイミングで記録を開始する）ことが可能な記録装置、記録方法、及び記録制御用のコンピュータプログラムを提供することを課題とする。 Examples of problems to be solved by the present invention include the above. In the present invention, when recording other content data input in accordance with the reproduction of one content data, the other content data is recorded at a suitable timing (or recording is started at an appropriate timing). It is an object to provide a recording apparatus, a recording method, and a computer program for recording control.
　上記課題を解決するために、記録装置は、第１コンテンツデータを再生すると共に、当該第１コンテンツデータの再生に先立って前記第１コンテンツデータの開始部分に付加されている第１付加データを再生する再生手段と、前記第１付加データ及び前記第１コンテンツデータの少なくとも一方の再生に合わせて入力される第２コンテンツデータを記録する記録手段とを備え、前記記録手段は、前記第１付加データの再生が終了した時点で前記第２コンテンツデータの記録を開始する。 In order to solve the above problem, the recording apparatus reproduces the first content data and reproduces the first additional data added to the start portion of the first content data prior to the reproduction of the first content data. Reproducing means for recording, and recording means for recording second content data input in accordance with reproduction of at least one of the first additional data and the first content data, wherein the recording means includes the first additional data. The recording of the second content data is started when the reproduction of is finished.
　上記課題を解決するために、記録方法は、第１コンテンツデータを再生すると共に、当該第１コンテンツデータの再生に先立って前記第１コンテンツデータの開始部分に付加されている第１付加データを再生する再生工程と、前記第１付加データ及び前記第１コンテンツデータの少なくとも一方の再生に合わせて入力される第２コンテンツデータを記録する記録工程とを備え、前記記録工程は、前記第１付加データの再生が終了した時点で前記第２コンテンツデータの記録を開始する。 In order to solve the above problem, the recording method reproduces the first content data and reproduces the first additional data added to the start portion of the first content data prior to the reproduction of the first content data.

　以下、記録装置、記録方法、及び記録制御用のコンピュータプログラムの実施形態について順に説明する。 Hereinafter, embodiments of a recording apparatus, a recording method, and a computer program for recording control will be described in order.
　（記録装置の実施形態）
　本実施形態の記録装置は、第１コンテンツデータを再生すると共に、当該第１コンテンツデータの再生に先立って前記第１コンテンツデータの開始部分に付加されている第１付加データを再生する再生手段と、前記第１付加データ及び前記第１コンテンツデータの少なくとも一方の再生に合わせて入力される第２コンテンツデータを記録する記録手段とを備え、前記記録手段は、前記第１付加データの再生が終了した時点で前記第２コンテンツデータの記録を開始する。 (Embodiment of recording apparatus)
The recording apparatus of the present embodiment reproduces the first content data and reproduces the first additional data added to the start portion of the first content data prior to the reproduction of the first content data. And recording means for recording second content data input in accordance with the reproduction of at least one of the first additional data and the first content data, and the recording means finishes reproducing the first additional data At that time, the recording of the second content data is started.
　本実施形態の配信装置によれば、再生手段は、第１コンテンツデータ及び第１付加データを再生することができる。第１コンテンツデータは、再生手段によって再生可能な任意のデータであってよく、例えば楽曲データや映像データ等が一例としてあげられる。第１付加データは、第１コンテンツデータの開始部分（言い換えれば、先頭部分）に付加されているデータである。言い換えれば、第１付加データは、第１コンテンツデータの開始部分を指し示す（或いは、特定する又は識別する）データである。従って、第１コンテンツデータの再生は、第１付加データの再生が行われた後に行われる。言い換えれば、第１付加データの再生が行われる場合には、その次に第１コンテンツで－が再生される。 According to the distribution apparatus of the present embodiment, the reproduction means can reproduce the first content data and the first additional data. The first content data may be arbitrary data that can be reproduced by the reproduction means, and examples thereof include music data and video data. The first additional data is data added to the start portion (in other words, the head portion) of the first content data. In other words, the first additional data is data indicating (or specifying or identifying) the start portion of the first content data. Therefore, the reproduction of the first content data is performed after the reproduction of the first additional data. In other words, when the first additional data is played back,-is played back with the first content next.
　記録手段は、当該記録装置に入力される第２コンテンツデータを記録することができる。特に、記録手段は、第１コンテンツデータ及び第１付加データの少なくとも一方の再生に合わせて、第２コンテンツデータを記録する。このとき、記録手段は、例えば任意の記録媒体等に第２コンテンツデータを記録してもよい。 The recording means can record the second content data input to the recording device. In particular, the recording unit records the second content data in accordance with the reproduction of at least one of the first content data and the first additional data. At this time, the recording means may record the second content data on, for example, an arbitrary recording medium.
　本実施形態では特に、記録手段は、再生手段による第１付加データの再生が終了した時点で第２コンテンツデータの記録を開始する。つまり、記録手段は、第１付加データの再生の終了（つまり、第１コンテンツデータの再生の開始）に合わせて、第２コンテンツデータの記録を開始する。 Particularly in the present embodiment, the recording means starts recording the second content data when the reproduction of the first additional data by the reproducing means is completed. In other words, the recording means starts recording the second content data at the end of the reproduction of the first additional data (that is, the start of the reproduction of the first content data).
　このように、本実施形態の記録装置は、第２コンテンツデータの記録と並行して再生される第１付加データ及び第１コンテンツデータの再生状態に応じて、第２コンテンツデータの記録を開始する（或いは、第２コンテンツデータを記録する）ことができる。つまり、本実施形態の記録装置は、時間的なばらつきが生じにくい第１付加データの再生タイミング（言い換えれば、第１コンテンツデータの再生タイミング）に応じて第２コンテンツデータの記録を開始することができる。言い換えれば、本実施形態の記録装置は、相対的に時間的なばらつきが生じやすいユーザの操作等に応じて第２コンテンツデータの記録を開始しなくともよい。このため、本実施形態の記録装置は、第１コンテンツデータの再生に合わせて入力される第２コンテンツデータを記録する場合に、当該第２コンテンツデータを好適なタイミングで記録することができる。 As described above, the recording apparatus of the present embodiment starts recording the second content data in accordance with the reproduction state of the first additional data and the first content data reproduced in parallel with the recording of the second content data. (Alternatively, the second content data can be recorded). That is, the recording apparatus of the present embodiment can start recording the second content data in accordance with the reproduction timing of the first additional data that is unlikely to vary in time (in other words, the reproduction timing of the first content data). it can. In other words, the recording apparatus of the present embodiment does not have to start recording the second content data in response to a user operation or the like that is likely to cause a temporal variation. For this reason, the recording apparatus of the present embodiment can record the second content data at a suitable timing when recording the second content data input in accordance with the reproduction of the first content data.
　本実施形態の記録装置の一の態様では、前記記録手段は、前記第１コンテンツデータの再生が開始した時点で前記第２コンテンツデータの記録を開始する。 In one aspect of the recording apparatus of the present embodiment, the recording unit starts recording the second content data when the reproduction of the first content data is started.
　この態様によれば、記録手段は、第１付加データの再生の終了（つまり、第１コンテンツデータの再生の開始）に合わせて、第２コンテンツデータの記録を開始することができる。従って、この態様の記録装置は、第１コンテンツデータの再生に合わせて入力される第２コンテンツデータを記録する場合に、当該第２コンテンツデータを好適なタイミングで記録することができる。 According to this aspect, the recording means can start recording the second content data in accordance with the end of the reproduction of the first additional data (that is, the start of the reproduction of the first content data). Therefore, the recording apparatus of this aspect can record the second content data at a suitable timing when recording the second content data input in accordance with the reproduction of the first content data.
　本実施形態の記録装置の他の態様では、前記記録手段は、前記第１付加データの再生が終了した後に入力される前記第２コンテンツデータを記録する。 In another aspect of the recording apparatus of the present embodiment, the recording unit records the second content data input after the reproduction of the first additional data is completed.
　この態様によれば、記録手段は、第１付加データの再生が終了した後に（つまり、第１コンテンツデータの再生が開始された後に）入力される第２コンテンツデータを記録することができる。つまり、記録手段は、実質的には、第１付加データの再生の終了（つまり、第１コンテンツデータの再生の開始）に合わせて、第２コンテンツデータの記録を開始することができる。従って、この態様の記録装置は、第１コンテンツデータの再生に合わせて入力される第２コンテンツデータを記録する場合に、当該第２コンテンツデータを好適なタイミングで記録することができる。 According to this aspect, the recording means can record the second content data input after the reproduction of the first additional data is completed (that is, after the reproduction of the first content data is started). In other words, the recording means can start recording the second content data substantially at the end of the reproduction of the first additional data (that is, the start of the reproduction of the first content data). Therefore, the recording apparatus of this aspect can record the second content data at a suitable timing when recording the second content data input in accordance with the reproduction of the first content data.
　本実施形態の記録装置の他の態様では、前記記録手段は、前記第１コンテンツデータの再生が開始した後に入力される前記第２コンテンツデータを記録する。 In another aspect of the recording apparatus of the present embodiment, the recording means records the second content data input after the reproduction of the first content data is started.
　この態様によれば、記録手段は、第１付加データの再生が終了した後に（つまり、第１コンテンツデータの再生が開始された後に）入力される第２コンテンツデータを記録することができる。つまり、記録手段は、実質的には、第１付加データの再生の終了（つまり、第１コンテンツデータの再生の開始）に合わせて、第２コンテンツデータの記録を開始することができる。従って、この態様の記録装置は、第１コンテンツデータの再生に合わせて入力される第２コンテンツデータを記録する場合に、当該第２コンテンツデータを好適なタイミングで記録することができる。 According to this aspect, the recording means can record the second content data input after the reproduction of the first additional data is completed (that is, after the reproduction of the first content data is started). In other words, the recording means can start recording the second content data substantially at the end of the reproduction of the first additional data (that is, the start of the reproduction of the first content data). Therefore, the recording apparatus of this aspect can record the second content data at a suitable timing when recording the second content data input in accordance with the reproduction of the first content data.
　本実施形態の記録装置の他の態様では、前記記録手段は、(i)前記第１付加データが再生されている間は、前記第２コンテンツデータの開始部分を特定するための第２付加データを記録すると共に、(ii)前記第１付加データの再生が終了した時点で前記第２付加データに続けて前記第２コンテンツデータの記録を開始する。 In another aspect of the recording apparatus of the present embodiment, the recording means is configured to: (i) second additional data for specifying a start portion of the second content data while the first additional data is being reproduced. (Ii) When the reproduction of the first additional data is completed, recording of the second content data is started following the second additional data.
　この態様によれば、記録手段は、第２コンテンツデータの記録に先立って、第２付加データを記録することができる。つまり、記録手段は、(i)第１付加データが再生されるタイミングで第２付加データを記録すると共に、(ii)第１コンテンツデータが再生されるタイミングで第２コンテンツデータを記録することができる。このため、記録手段は、第１付加データ及び第１コンテンツデータの再生タイミングに応じた適切なタイミングで、第２付加データ及び第２コンテンツデータを記録することができる。 According to this aspect, the recording means can record the second additional data prior to recording the second content data. That is, the recording means can record (i) the second additional data at the timing when the first additional data is reproduced, and (ii) record the second content data at the timing when the first content data is reproduced. it can. Therefore, the recording unit can record the second additional data and the second content data at an appropriate timing according to the reproduction timing of the first additional data and the first content data.
　加えて、記録手段によって記録された第２コンテンツデータは、その開始部分に第２付加データが付加されている。このため、第２付加データが付加された第２コンテンツデータは、記録後には、第１付加データが付加された新たな第１コンテンツデータとして利用することができる。 In addition, the second content data recorded by the recording means has the second additional data added to the start portion thereof. Therefore, the second content data to which the second additional data is added can be used as new first content data to which the first additional data is added after recording.
　上述の如く第２付加データを記録する記録装置の態様では、(i)前記第１付加データが再生されている間は、前記第２付加データが前記記録手段に入力され且つ(ii)前記第１付加データの再生が終了した後に前記第２コンテンツデータが前記記録手段に入力されるように前記記録手段に対するデータ入力経路を切り替える経路制御手段を更に備え、前記記録手段は、前記経路制御手段を介して入力される前記第２付加データ及び前記第２コンテンツデータを記録するように前記記録手段を制御するように構成してもよい。 In the aspect of the recording apparatus for recording the second additional data as described above, (i) while the first additional data is being reproduced, the second additional data is input to the recording means, and (ii) the second additional data is recorded. 1 further comprising path control means for switching a data input path for the recording means so that the second content data is input to the recording means after the reproduction of the additional data is completed, and the recording means includes the path control means. The recording unit may be controlled so as to record the second additional data and the second content data input via the terminal.
　このように構成すれば、記録手段は、(i)第１付加データが再生されるタイミングで第２付加データを記録すると共に、(ii)第１コンテンツデータが再生されるタイミングで第２コンテンツデータを記録することができる。 According to this structure, the recording means records (i) the second additional data at the timing when the first additional data is reproduced, and (ii) the second content data at the timing when the first content data is reproduced. Can be recorded.
　（記録方法の実施形態）
　本実施形態の記録方法は、第１コンテンツデータを再生すると共に、当該第１コンテンツデータの再生に先立って前記第１コンテンツデータの開始部分に付加されている第１付加データを再生する再生工程と、前記第１付加データ及び前記第１コンテンツデータの少なくとも一方の再生に合わせて入力される第２コンテンツデータを記録する記録工程とを備え、前記記録工程は、前記第１付加データの再生が終了した時点で前記第２コンテンツデータの記録を開始する。 (Embodiment of recording method)

　以下、図面を参照しながら、記録装置、記録方法、及び記録制御用のコンピュータプログラムの実施例について説明する。尚、以下では、記録装置の一例として、既存の音楽データ（既存音楽データ２０）を再生しながら、ユーザの演奏（例えば、歌唱や楽器の演奏等）に応じて生成される演奏データを録音音楽データ３０として新たに記録する記録装置１を用いて説明を進める。但し、記録装置として、音楽データ以外の任意のコンテンツデータ（例えば、映像データや、静止画データや、テキストデータや、その他の任意のデータ）を再生しながら他のコンテンツデータを記録する記録装置を採用してもよい。 Hereinafter, embodiments of a recording apparatus, a recording method, and a computer program for recording control will be described with reference to the drawings. In the following description, as an example of a recording device, performance data generated in accordance with a user's performance (for example, singing or playing a musical instrument) while recording existing music data (existing music data 20) is recorded music. The description will be given using the recording apparatus 1 that newly records data 30. However, as a recording device, a recording device that records other content data while reproducing arbitrary content data other than music data (for example, video data, still image data, text data, and other arbitrary data). It may be adopted.
　（１）記録装置１の構成
　図１を参照して、本実施例の記録装置１の構成について説明する。ここに、図１は、本実施例の記録装置１の構成を示すブロック図である。 (1) Configuration of Recording Apparatus 1 The configuration of the recording apparatus 1 of this embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of the recording apparatus 1 of this embodiment.
　図１に示すように、記録装置１は、再生部１１と、データ経路切替部１２と、スピーカ１３と、マイク１４と、記録バッファ１５とを備えている。 As shown in FIG. 1, the recording apparatus 1 includes a reproduction unit 11, a data path switching unit 12, a speaker 13, a microphone 14, and a recording buffer 15.
　再生部１１は、「再生手段」の一具体例であって、既存音楽データ２０を再生する。尚、記録装置１は、外部の装置から既存音楽データ２０を取得してもよい。この場合、再生部１１は、例えば外部の装置と通信する通信部と、通信部が取得した既存音楽データ２０に対して再生処理（例えば、復号化処理や復調処理等）を行う処理回路等を備えていてもよい。或いは、記録装置１は、記録装置１にローディングされる又は設置されている記録媒体に記録された既存音楽データ２０を取得してもよい。この場合、再生部１１は、例えば記録媒体に記録された既存データ２０を読み出す再生ヘッド（例えば、磁気ヘッドや光ピックアップ等）と、再生ヘッドが読み出した既存音楽データ２０に対して再生処理を行う処理回路等を備えていてもよい。もちろん、記録装置１は、その他の手法で既存音楽データ２０を取得してもよい。 The playback unit 11 is a specific example of “playback means” and plays back existing music data 20. Note that the recording device 1 may acquire the existing music data 20 from an external device. In this case, the playback unit 11 includes, for example, a communication unit that communicates with an external device, and a processing circuit that performs playback processing (for example, decoding processing and demodulation processing) on the existing music data 20 acquired by the communication unit. You may have. Alternatively, the recording device 1 may acquire the existing music data 20 loaded on the recording device 1 or recorded on a recording medium. In this case, the playback unit 11 performs playback processing on the existing music data 20 read by the playback head (for example, a magnetic head or an optical pickup) that reads the existing data 20 recorded on the recording medium, for example. A processing circuit or the like may be provided. Of course, the recording apparatus 1 may acquire the existing music data 20 by other methods.
　既存音楽データ２０は、例えば楽曲や演奏等の音楽を構成するデータ（例えば、ＭＩＤＩデータや、ＭＰ３データや、ＡＡＣデータ等）である。既存音楽データ２０の開始部分（言い換えれば、先頭部分）には、当該部分が既存音楽データ２０の開始部分であることを示す開始位置検出データ２１が付加されている。従って、再生部１１が既存音楽データ２０を再生する際には、既存音楽データ２０の再生に先立って開始位置検出データ２１の再生が行われる。尚、開始位置検出データ２１は、開始部分を適切に示すことができる限りはどのようなデータであってもよい。 The existing music data 20 is data (for example, MIDI data, MP3 data, AAC data, etc.) constituting music such as music and performance. The start position detection data 21 indicating that the part is the start part of the existing music data 20 is added to the start part (in other words, the head part) of the existing music data 20. Therefore, when the reproducing unit 11 reproduces the existing music data 20, the start position detection data 21 is reproduced prior to the reproduction of the existing music data 20. The start position detection data 21 may be any data as long as the start portion can be appropriately indicated.
　データ経路切替部１２は、「経路制御手段」の一具体例であって、再生部１１とスピーカ１３とマイク１４と記録バッファ１５との間のデータ経路を制御する。より具体的には、データ経路切替部１２は、３端子スイッチ１２１と、合成器１２２と、スイッチ制御部１２３とを備える。３端子スイッチ１２１が備える第１端子１２１ａは、再生部１１及び合成器１２２の第１入力端子の夫々に電気的に又は回路的に接続される。３端子スイッチ１２１が備える第２端子１２１ｂは、マイク１４及び合成器１２２の第２入力端子の夫々に電気的に又は回路的に接続される。３端子スイッチ１２１が備える第３端子１２１ｃは、記録バッファ１５に電気的に又は回路的に接続される。３端子スイッチ１２１は、第３端子１２１ｃが第１端子１２１ａ及び第２端子１２１ｂのいずれかと電気的に接続されるように、スイッチングを行う。合成器１２２の出力端子は、スピーカ１３に接続される。スイッチ１２１が行うスイッチングは、スイッチ制御部１２３によって制御される。尚、スイッチ制御部１２３は、再生部１１によって再生されているデータの種類に応じて、スイッチ１２１の動作を制御する。 The data path switching unit 12 is a specific example of “path control means”, and controls the data path among the playback unit 11, the speaker 13, the microphone 14, and the recording buffer 15. More specifically, the data path switching unit 12 includes a three-terminal switch 121, a combiner 122, and a switch control unit 123. The first terminal 121 a included in the three-terminal switch 121 is electrically or circuitably connected to the reproduction unit 11 and the first input terminal of the combiner 122. The second terminal 121 b included in the three-terminal switch 121 is electrically or circuitically connected to the microphone 14 and the second input terminal of the synthesizer 122. A third terminal 121c included in the three-terminal switch 121 is electrically or circuitably connected to the recording buffer 15. The three-terminal switch 121 performs switching so that the third terminal 121c is electrically connected to either the first terminal 121a or the second terminal 121b. The output terminal of the synthesizer 122 is connected to the speaker 13. Switching performed by the switch 121 is controlled by the switch control unit 123. Note that the switch control unit 123 controls the operation of the switch 121 according to the type of data being reproduced by the reproduction unit 11.
　第１端子１２１ａと第３端子１２１ｃとが電気的に接続されている場合には、再生部１１が再生した既存音楽データ２０及び開始位置検出データ２１の少なくとも一方は、記録バッファ１５へと出力される。加えて、この場合には、マイク１４から入力される演奏データは、合成器１２２を介してスピーカ１３から出力される。つまり、記録装置１のユーザが行った演奏（つまり、マイク１４を介して記録装置１に入力された演奏）が、スピーカ１３から流れる。 When the first terminal 121a and the third terminal 121c are electrically connected, at least one of the existing music data 20 and the start position detection data 21 reproduced by the reproducing unit 11 is output to the recording buffer 15. The In addition, in this case, performance data input from the microphone 14 is output from the speaker 13 via the synthesizer 122. That is, a performance performed by the user of the recording apparatus 1 (that is, a performance input to the recording apparatus 1 via the microphone 14) flows from the speaker 13.
　一方で、第２端子１２１ｂと第３端子１２１ｃとが電気的に接続されている場合には、再生部１１が再生した既存音楽データ２０及び開始位置検出データ２１の少なくとも一方は、合成器１２２へと出力される。加えて、この場合には、マイク１４から入力される演奏データは、合成器１２２へと出力される。従って、スピーカ１３からは、既存音楽データ２０と演奏データとが合成器１２２で合成されることで生成される合成音楽データが出力される。つまり、既存音楽データ２０に応じた音楽に加えて記録装置１のユーザが行った演奏（つまり、マイク１４を介して記録装置１に入力された演奏）が、スピーカ１３から流れる。 On the other hand, when the second terminal 121b and the third terminal 121c are electrically connected, at least one of the existing music data 20 and the start position detection data 21 reproduced by the reproducing unit 11 is sent to the synthesizer 122. Is output. In addition, in this case, performance data input from the microphone 14 is output to the synthesizer 122. Therefore, the synthesized music data generated by synthesizing the existing music data 20 and the performance data by the synthesizer 122 is output from the speaker 13. That is, in addition to music corresponding to the existing music data 20, a performance performed by the user of the recording device 1 (that is, a performance input to the recording device 1 via the microphone 14) flows from the speaker 13.
　スピーカ１３は、音楽の出力を行う装置である。上述したように、スピーカ１３は、再生部１１が再生した既存音楽データ２０や、マイク１４を介して入力される演奏データを、音楽として出力する。 Speaker 13 is a device that outputs music. As described above, the speaker 13 outputs the existing music data 20 reproduced by the reproducing unit 11 and the performance data input via the microphone 14 as music.
　マイク１４は、ユーザの演奏の入力を受け付ける装置である。上述したように、マイク１４を介して入力されたユーザの演奏（つまり、演奏データ）は、スイッチ１２１の状態に応じて、スピーカ１３及び記録バッファ１５の少なくとも一方に出力される。 The microphone 14 is a device that accepts user performance input. As described above, the user performance (that is, performance data) input via the microphone 14 is output to at least one of the speaker 13 and the recording buffer 15 in accordance with the state of the switch 121.
　記録バッファ１５は、「記録手段」の一例であって、マイク１４を介して入力されたユーザの演奏（つまり、演奏データ）を、録音音楽データ３０として記録するための記憶装置である。加えて、記録バッファ１５は、録音音楽データ３０の開始部分（言い換えれば、先頭部分）に、当該部分が録音音楽データ３０の開始部分であることを示す開始位置検出データ３１が付加されるように、開始位置検出データ３１を記録する。尚、開始位置検出データ３１は、開始部分を適切に示すことができる限りはどのようなデータであってもよい。記録バッファ１５として、例えば、ＲＡＭやフラッシュメモリ等の半導体メモリや、ハードディスク等が一例としてあげられる。 The recording buffer 15 is an example of “recording means”, and is a storage device for recording user performance (that is, performance data) input via the microphone 14 as recorded music data 30. In addition, in the recording buffer 15, start position detection data 31 indicating that the portion is the start portion of the recorded music data 30 is added to the start portion (in other words, the head portion) of the recorded music data 30. The start position detection data 31 is recorded. The start position detection data 31 may be any data as long as the start portion can be appropriately indicated. Examples of the recording buffer 15 include a semiconductor memory such as a RAM and a flash memory, a hard disk, and the like.
　（２）楽曲配信システムにおける動作の流れ
　続いて、図２から図６を参照して、本実施例の記録装置１の動作の流れについて説明する。ここに、図２は、本実施例の記録装置１の動作の流れを示すフローチャートである。図３から図６は、本実施例の記録装置１の動作の一過程における記録装置１内のデータの状態を示すブロック図である。 (2) Flow of Operation in Music Distribution System Next, the flow of operation of the recording apparatus 1 of the present embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation flow of the recording apparatus 1 of the present embodiment. 3 to 6 are block diagrams showing the state of data in the recording apparatus 1 in one process of the operation of the recording apparatus 1 of the present embodiment.
　図２に示すように、再生部１１は、既存音楽データ２０及び開始位置検出データ２１の少なくとも一方の再生を開始する（ステップＳ１０１：図２）。 As shown in FIG. 2, the playback unit 11 starts playback of at least one of the existing music data 20 and the start position detection data 21 (step S101: FIG. 2).
　ここで、既存音楽データ２０の開始部分に開始位置検出データ２１が付加されていることを考慮すれば、再生部１１は、まず開始位置検出データ２１の再生を開始することになると推定される。このとき、スイッチ制御部１２３は、スイッチ１２１が再生部１１と記録バッファ１５とを接続するスイッチングを行うようにスイッチ１２１の動作を制御する。その結果、スイッチ１２１は、再生部１１と記録バッファ１５とが接続されるようにスイッチングを行う（ステップＳ１０２：図２）。言い換えれば、スイッチ１２１は、再生部１１が開始位置検出データ２１を再生している間（言い換えれば、再生部１１が既存音楽データ２０の再生を開始していない間）は、再生部１１と記録バッファ１５とが接続されるようにスイッチングを行う。 Here, considering that the start position detection data 21 is added to the start portion of the existing music data 20, it is estimated that the playback unit 11 first starts to play back the start position detection data 21. At this time, the switch control unit 123 controls the operation of the switch 121 so that the switch 121 performs switching for connecting the reproducing unit 11 and the recording buffer 15. As a result, the switch 121 performs switching so that the reproducing unit 11 and the recording buffer 15 are connected (step S102: FIG. 2). In other words, the switch 121 is recorded with the playback unit 11 while the playback unit 11 is playing back the start position detection data 21 (in other words, while the playback unit 11 has not started playback of the existing music data 20). Switching is performed so that the buffer 15 is connected.
　より具体的には、図３に示すように、スイッチ１２１は、第１端子１２１ａと第３端子１２１ｃとを接続するようにスイッチングを行う。この場合、図３に示すように、再生部１１が再生した開始位置検出データ２１は、記録バッファ１５へと出力される。加えて、この場合には、マイク１４から入力される演奏データは、合成器１２２を介してスピーカ１３から出力される。 More specifically, as shown in FIG. 3, the switch 121 performs switching so as to connect the first terminal 121a and the third terminal 121c. In this case, as shown in FIG. 3, the start position detection data 21 reproduced by the reproduction unit 11 is output to the recording buffer 15. In addition, in this case, performance data input from the microphone 14 is output from the speaker 13 via the synthesizer 122.
　その後、図４に示すように、再生部１１による再生が進むにつれて、記録バッファ１５は、再生部１１が再生した開始位置検出データ２１を、そのまま又は任意の情報処理を施した後に、開始位置検出データ３１として記録する（ステップＳ１０３：図２）。 Thereafter, as shown in FIG. 4, as playback by the playback unit 11 proceeds, the recording buffer 15 detects the start position as it is or after performing any information processing on the start position detection data 21 played by the playback unit 11. Data 31 is recorded (step S103: FIG. 2).
　その後、スイッチ制御部１２３は、再生部１１から出力されるデータを監視することで、開始位置検出データ２１の再生が終了したか否かを判定する（ステップＳ１０４：図２）。或いは、スイッチ制御部１２３は、再生部１１から出力されるデータを監視することで、既存音楽データ２０の再生が開始したか否かを判定してもよい。 Thereafter, the switch control unit 123 determines whether or not the reproduction of the start position detection data 21 is completed by monitoring the data output from the reproduction unit 11 (step S104: FIG. 2). Alternatively, the switch control unit 123 may determine whether or not the reproduction of the existing music data 20 has started by monitoring the data output from the reproduction unit 11.
　ステップＳ１０４の判定の結果、開始位置検出データ２１の再生が終了していない（或いは、既存音楽データ２０の再生が開始してない）と判定される場合には（ステップＳ１０４：Ｎｏ：図２）、記録バッファ１５は、再生部１１が再生した開始位置検出データ２１を、そのまま又は任意の情報処理を施した後に、開始位置検出データ３１として記録する動作を継続する（ステップＳ１０３：図２）。 As a result of the determination in step S104, when it is determined that the reproduction of the start position detection data 21 has not ended (or the reproduction of the existing music data 20 has not started) (step S104: No: FIG. 2). The recording buffer 15 continues the operation of recording the start position detection data 21 reproduced by the reproduction unit 11 as it is or after performing arbitrary information processing as the start position detection data 31 (step S103: FIG. 2).
　他方で、開始位置検出データ２１の再生が終了した（或いは、既存音楽データ２０の再生が開始した）と判定される場合には（ステップＳ１０４：Ｙｅｓ：図２）、スイッチ制御部１２３は、スイッチ１２１がマイク１４と記録バッファ１５とを接続するスイッチングを行うようにスイッチ１２１の動作を制御。その結果、スイッチ１２１は、マイク１４と記録バッファ１５とが接続されるようにスイッチングを行う（ステップＳ１０５：図２）。 On the other hand, when it is determined that the reproduction of the start position detection data 21 has ended (or the reproduction of the existing music data 20 has started) (step S104: Yes: FIG. 2), the switch control unit 123 switches the switch The operation of the switch 121 is controlled so that 121 performs switching for connecting the microphone 14 and the recording buffer 15. As a result, the switch 121 performs switching so that the microphone 14 and the recording buffer 15 are connected (step S105: FIG. 2).
　より具体的には、図５に示すように、スイッチ１２１は、第２端子１２１ｂと第３端子１２１ｃとを接続するようにスイッチングを行う。この場合、図５に示すように、再生部１１が再生した既存音楽データ２０は、合成器１２２を介してスピーカ１３へと出力される。加えて、この場合には、マイク１４から入力される演奏データは、記録バッファ１５へと出力されると共に、合成器１２２を介してスピーカ１３から出力される。 More specifically, as shown in FIG. 5, the switch 121 performs switching so as to connect the second terminal 121b and the third terminal 121c. In this case, as shown in FIG. 5, the existing music data 20 reproduced by the reproducing unit 11 is output to the speaker 13 via the synthesizer 122. In addition, in this case, performance data input from the microphone 14 is output to the recording buffer 15 and also output from the speaker 13 via the synthesizer 122.
　その後、図６に示すように、再生部１１による再生が進むにつれて、記録バッファ１５は、マイク１４から入力される演奏データを、そのまま又は任意の情報処理を施した後に、録音音楽データ３０として記録する（ステップＳ１０６：図２）。このとき、記録バッファ１５は、ステップＳ１０３で記録された開始位置検出データ３１に続けて録音音楽データ３０を記録する。つまり、記録バッファ１５は、ステップＳ１０３で記録された開始位置検出データ３１が録音音楽データ３０の開始部分に位置するように録音音楽データ３０を記録する。 Thereafter, as shown in FIG. 6, as playback by the playback unit 11 proceeds, the recording buffer 15 records the performance data input from the microphone 14 as recorded music data 30 as it is or after performing arbitrary information processing. (Step S106: FIG. 2). At this time, the recording buffer 15 records the recorded music data 30 following the start position detection data 31 recorded in step S103. That is, the recording buffer 15 records the recorded music data 30 so that the start position detection data 31 recorded in step S103 is positioned at the start portion of the recorded music data 30.
　以上説明したように、本実施例の記録装置１は、(i)再生部１１によって開始位置検出データ２１が再生されている間は、記録バッファ１５に開始位置検出データ３１を記録し、(ii)再生部１１によって既存音楽データ２０が再生されている間は、記録バッファ１５に録音音楽データ３０を記録することができる。言い換えれば、本実施例の記録装置１は、(i)再生部１１によって開始位置検出データ２１が再生されている間は、記録バッファ１５に開始位置検出データ３１を記録し、(ii)再生部１１による開始位置検出データ２１の再生が終了した時点で、記録バッファ１５に対する録音音楽データ３０の記録を開始することができる。更に言い換えれば、本実施例の記録装置１は、(i)再生部１１によって既存音楽データ２０の再生が開始される前は、記録バッファ１５に開始位置検出データ３１を記録し、(ii)再生部１１による既存音楽データ２０の再生が開始した時点で、記録バッファ１５に対する録音音楽データ３０の記録を開始することができる。 As described above, the recording apparatus 1 according to the present embodiment records (i) the start position detection data 31 in the recording buffer 15 while the reproduction unit 11 is reproducing the start position detection data 21, and (ii) While the existing music data 20 is being played back by the playback unit 11, the recorded music data 30 can be recorded in the recording buffer 15. In other words, the recording apparatus 1 of the present embodiment (i) records the start position detection data 31 in the recording buffer 15 while the reproduction unit 11 reproduces the start position detection data 21, and (ii) the reproduction unit. 11, the recording of the recorded music data 30 to the recording buffer 15 can be started. In other words, the recording apparatus 1 of the present embodiment (i) records the start position detection data 31 in the recording buffer 15 and (ii) reproduces before the reproduction of the existing music data 20 is started by the reproduction unit 11. When the reproduction of the existing music data 20 by the unit 11 is started, recording of the recorded music data 30 to the recording buffer 15 can be started.
　このように、再生部１１が再生する既存音楽データ２０及び開始位置検出データ２１に合わせて録音音楽データ３０及び開始位置検出データ３１を記録することで実現される技術的効果について、図７を参照して説明する。ここに、図７は、再生部１１が再生する既存音楽データ２０及び開始位置検出データ２１に合わせて録音音楽データ３０及び開始位置検出データ３１を記録することで実現される技術的効果を説明する模式図である。 As described above, with reference to FIG. 7, the technical effect realized by recording the recorded music data 30 and the start position detection data 31 in accordance with the existing music data 20 and the start position detection data 21 to be played back by the playback unit 11 will be described. To explain. FIG. 7 illustrates a technical effect realized by recording the recorded music data 30 and the start position detection data 31 in accordance with the existing music data 20 and the start position detection data 21 reproduced by the playback unit 11. It is a schematic diagram.
　図７（ａ）に示すように、開始位置検出データ２１が既存音楽データ２０に付加されなければ、ユーザは、例えば操作ボタン等を操作することで、録音音楽データ３０（つまり、演奏データ）の記録を開始する旨を指示する必要がある。しかしながら、操作ボタンの操作の精度やタイミング等によっては、記録バッファ１５内で録音音楽データ３０が記録される位置が、録音の都度異なったものとなってしまいかねない。例えば、図７（ａ）は、既存音楽データ２０の再生に合わせて、マイク１４を介して入力される演奏データの記録（つまり、ユーザの演奏の録音）が３回行われた例を示している。つまり、図７（ａ）は、１回目の録音で記録された録音音楽データ３０の開始部分と、２回目の録音で記録された録音音楽データ３０の開始部分と、３回目の録音で記録された録音データ３０の開始部分とが時間的に又は記録バッファ１５内での位置的にずれてしまう例を示している。 As shown in FIG. 7A, if the start position detection data 21 is not added to the existing music data 20, the user operates the operation button or the like, for example, to record the recorded music data 30 (that is, performance data). It is necessary to instruct to start recording. However, the position where the recorded music data 30 is recorded in the recording buffer 15 may be different for each recording depending on the accuracy and timing of the operation of the operation buttons. For example, FIG. 7A shows an example in which performance data input through the microphone 14 (that is, recording of the user's performance) is performed three times in accordance with the reproduction of the existing music data 20. Yes. That is, FIG. 7A shows the start portion of the recorded music data 30 recorded in the first recording, the start portion of the recorded music data 30 recorded in the second recording, and the third recording. In this example, the recorded data 30 is shifted from the start of the recording data 30 in time or in position in the recording buffer 15.
　しかるに、本実施例では、図７（ｂ）に示すように、既存音楽データ２０に付加されている開始位置検出データ２１の再生タイミングに応じて録音音楽データ３０及び開始位置検出データ３１が記録されるため、記録バッファ１５内で録音音楽データ３０が記録される位置が揃う又は揃いやすくなる。或いは、仮に記録バッファ１５内で録音音楽データ３０が記録される位置が録音の都度異なったものとなってしまったとしても、記録装置１は、録音音楽データ３０に付加されている開始位置検出データ３１を参照すれば、録音音楽データ３０の開始部分を容易に且つ迅速に特定することができる。従って、仮に記録バッファ１５内で録音音楽データ３０が記録される位置が録音の都度異なったものとなってしまった場合であっても、記録装置１は、録音音楽データ３０の開始部分から適切に再生を開始することができる。或いは、仮に記録バッファ１５内で録音音楽データ３０が記録される位置が録音の都度異なったものとなってしまった場合であっても、記録装置１は、録音音楽データ３０の開始部分を的確に特定しながら当該録音音楽データ３０に対して任意のデータ処理（例えば、ファイル化処理等）を行うことができる。 However, in this embodiment, as shown in FIG. 7B, the recorded music data 30 and the start position detection data 31 are recorded in accordance with the reproduction timing of the start position detection data 21 added to the existing music data 20. Therefore, the positions where the recorded music data 30 are recorded in the recording buffer 15 are aligned or easily aligned. Alternatively, even if the position where the recorded music data 30 is recorded in the recording buffer 15 is different every time recording is performed, the recording apparatus 1 can detect the start position detection data added to the recorded music data 30. If 31 is referred, the start part of the recording music data 30 can be specified easily and rapidly. Therefore, even if the position where the recorded music data 30 is recorded in the recording buffer 15 is different every time recording is performed, the recording apparatus 1 can appropriately start from the beginning of the recorded music data 30. Playback can be started. Alternatively, even if the recording music data 30 is recorded in the recording buffer 15 at a position where the recording music data 30 is different every time recording is performed, the recording apparatus 1 accurately determines the start portion of the recording music data 30. Arbitrary data processing (for example, file processing or the like) can be performed on the recorded music data 30 while specifying.
