All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
In order to solve the problem that the playing time of audio cannot be shortened under the condition that the audio quality cannot be guaranteed in the prior art, so that the efficiency of a user for reviewing audio content is low, the invention provides an audio processing method, and an execution main body of the method can be but is not limited to a mobile phone, a tablet computer, a wearable device and the like, and can be configured to execute at least one of the user terminals of the method provided by the embodiment of the invention, or the execution main body of the method can also be a client self capable of executing the method.
For convenience of description, the following description will be made on embodiments of the method, taking an execution subject of the method as an example of an electronic device capable of executing the method. It is to be understood that the implementation of the method as an electronic device is merely an exemplary illustration and should not be construed as a limitation of the method.
Specifically, the audio processing method provided by the invention comprises the following steps: detecting a target time period in the first audio; under the condition that the first audio has the target time period, deleting the target time period in the first audio to obtain a second audio; generating a target audio according to the target time period and the second audio; the target time period is a time period in which the voltage amplitude of the electric signal in the first audio is smaller than or equal to a preset amplitude threshold value and the time length is larger than a first preset duration threshold value.
The target time period in the audio can be detected, and the target audio with the target time period deleted can be generated, so that the playing time of the audio can be shortened under the condition of ensuring the audio quality, the time of a user can be saved, and the efficiency of the user in learning or working based on the audio can be improved.
The following describes in detail an implementation process of the audio processing method shown in fig. 1 with reference to an implementation flow diagram of the audio processing method, including:
the first audio may include an audio that is completely recorded and an audio that is not completely recorded.
It should be understood that in practical applications, users often have a long pause or a target time period of multi-person discussion in the audio recorded at a conference site, a training site or a lecture site, and the presence of the audio may take a lot of waiting time for the users when the users review the recorded audio. In order to shorten the playing time of the audio and further save the time of a user under the condition of ensuring the audio quality, the embodiment of the invention can receive the preset operation of the first audio and delete the target time period in the audio in response to the preset operation of the first audio.
Optionally, the user may perform a preset operation on the first audio when importing, playing, saving, or recording the first audio, so as to delete the target time period in the first audio. Specifically, in the method provided by the embodiment of the present invention, the preset operation on the first audio includes at least one of:
importing a first audio;
playing the first audio;
a save operation for the first audio;
and recording the first audio.
When the first audio is the audio which is recorded completely, the user can accept the import operation or the play operation of the first audio to play the first audio, and at this time, the target time period in the first audio can be deleted in response to the import operation or the play operation; when the first audio is the audio which is recorded but not stored, accepting the storage operation of the user on the first audio to store the first audio, and at this time, deleting the target time period in the first audio in response to the storage operation; when the first audio is the audio being recorded, the recording operation of the first audio by the user may be accepted to record the first audio, and at this time, the target time period in the first audio may be deleted in response to the recording operation.
102, deleting a target time period in the first audio to obtain a second audio under the condition that the target time period exists in the first audio;
it should be understood that, in the method provided by the embodiment of the present invention, the target time period is a time period in which the voltage amplitude of the audio electrical signal in the first audio is less than or equal to the preset amplitude threshold value and the time length is greater than the first preset time length threshold value.
Specifically, as shown in fig. 2, for a schematic diagram of a target time period in audio provided by an embodiment of the present invention, a position 201, a position 203, and a position 204 in fig. 2 may be defined as the target time period. The target time period may be a time period in which the human ear cannot hear or cannot hear sound, i.e., a time period in which the voltage amplitude of the electrical audio signal in the first audio frequency is less than or equal to-60 dB.
Moreover, in order to avoid the excessive processing of the first audio, which may result in the increase of the workload and the power consumption of the electronic device, the first preset duration threshold may be empirically set as a critical point of the waiting duration acceptable to the user, for example, the first preset duration threshold may be set to 5 seconds. Therefore, the time period within 5 seconds in which the human ears cannot hear or cannot hear the sound can be deleted, and the user is prevented from wasting time to wait for the audio playing in the time period. Or, in another embodiment, the user may further set the first preset duration threshold according to a preference, so that the audio processing method provided by the embodiment of the present invention is more personalized.
Specifically, when a preset operation of the user on the first audio is received, an audio recognition algorithm built in the audio application may be started, a target time period in the first audio is recognized, and the target time period is deleted.
Optionally, when the user is recording the first audio, in order to delete the target time period in the first audio in real time, the embodiment of the present invention may detect the target time period and delete the target time period during recording. Specifically, when the preset operation on the first audio includes a recording operation on the first audio, and in a case that the first audio has a target time period, deleting the target time period in the first audio to obtain a second audio, including:
under the condition that the first audio has the target time period, stopping recording the first audio, and deleting the target time period in the first audio;
after the recording of the first audio is suspended, if the voltage amplitude of the audio electrical signal is detected to be larger than a preset amplitude threshold value, the recording of the first audio is continued, and a second audio is obtained.
Specifically, in the process of recording the first audio, the target time period may be deleted by skipping the recording of the target time period, that is, in the case where the target time period is detected, the recording of the first audio is suspended and the detected target time period is deleted, and the second audio is generated.
And 103, generating a target audio according to the target time period and the second audio.
Specifically, in order to immediately process the first audio after receiving a preset operation of the user on the first audio, so as to provide the user with a target audio with a reasonable time interval of the audio electrical signal in time, the embodiment of the present invention provides a method and an apparatus for processing a first audio. Optionally, in the method provided in this embodiment of the present invention, generating the target audio piece according to the target time period and the second audio includes:
obtaining a position to be inserted in a second audio frequency based on the position of the target time period in the first audio frequency;
inserting audio electrical signals of interval time periods at a position to be inserted in the second audio to generate target audio;
the voltage amplitude of the audio electrical signal of the interval time period is smaller than or equal to a preset amplitude threshold value, and the time length of the interval time period is smaller than or equal to a second preset duration threshold value; the first preset duration threshold is greater than the second preset duration threshold.
It should be understood that, when the preset operation on the first audio includes one of an import operation, a play operation, or a save operation, in order to avoid that the audio before and after the target time period is too close to each other to make the human ear indistinguishable, the position of the target time period may be marked when the target time period is deleted, and then the interval time period may be inserted into the marked position, so that a time interval that the human ear can distinguish between the audio before and after the target time period can be provided.
Optionally, the interval time period is an audio that can not be heard by the human ear inserted with the second audio, as long as the audio functions before and after the interval, so the time length of the interval time period is not too long, and the second preset time threshold may be smaller than the first preset time threshold, for example, the second preset time threshold may be 1 second.
Further, in order to enable the user to select the audio that the user wants to play, after deleting the target time period or/and inserting the interval time period according to the above method, the embodiment of the present invention can additionally generate the target audio that corresponds to the first audio and has deleted the target time period, and present the first audio and the target audio together in the interface for the user to select.
Optionally, in order to enable the user to distinguish the first audio from the target audio and to link the first audio and the corresponding target audio, a suffix such as "[ abbreviated form ]" may be added to the name of the first audio as the name of the target audio for the user to distinguish.
The following describes embodiments of the present invention in detail by way of a flow diagram.

601, a user starts to record a first audio;

After the user opens the audio playing interface, a 'normal playing mode' button and an 'intelligent time-saving playing mode' button can be displayed on the playing interface, so that the user can switch the playing mode when playing the audio. Wherein the "normal play mode" button corresponds to the first audio and the "smart time saving play mode" button corresponds to the target audio. In addition, "remind" can be shown below "the intelligent playback mode that saves time": a play time saving of 23%, i.e. 45 seconds, can be achieved. The word of' is used for prompting the user how much time the target audio frequency can save the user and the percentage of the saved time in the total time, so that the user can conveniently select the playing mode according to the playing requirement.
The audio processing method provided by the embodiment of the invention can detect the target time period in the first audio; under the condition that the first audio has the target time period, deleting the target time period in the first audio to obtain a second audio; generating a target audio according to the target time period and the second audio; the target time period is a time period in which the voltage amplitude of the electric signal in the first audio is smaller than or equal to a preset amplitude threshold value and the time length is larger than a first preset duration threshold value.
