落を招き、必ずしも有効では無い。 As is clear from the above description, in a conventional audio signal control device, after an input signal including an audio signal and a control signal is PCM encoded,
The audio signal is stored in the audio signal storage file 6. Therefore,
When such an input signal is later extracted from the voice signal storage file 6, decoded by the voice code decoding circuit 82, and then sent to the communication path 7 as an output signal, the subscriber 3 to whom the output signal is transmitted receives the voice signal. Not only the signal but also the control signal (PB signal) will be heard, which will make the subscriber 3 feel uncomfortable.
Note that when the processing device 9 receives a control signal instructing the end of accumulation from the PB receiver 81, the processing device 9 stores the audio data buffer 83 after the control signal detection time (for example, several tens of milliseconds) from the time of transmission. stops transferring the PCM encoded input signal stored in the audio signal storage file 6;
It is also contemplated to prevent the control signal from being stored in the audio signal storage file 6. However, the load on the processing device 9 increases due to the removal of such control signals, and the control signals that are mixed with the voice signals and sent out are necessary for a subscriber who is on a call to temporarily suspend the accumulation of voice signals. The above-mentioned processing is not necessarily effective in removing the audio signal because it causes audio signal loss.

FIG. 3 is a diagram showing an audio signal control device according to an embodiment of the present invention. Note that the same reference numerals indicate the same objects throughout the figures. Also in FIG. 3, the audio signal control device is composed of a plurality of communication path corresponding sections 8 corresponding to the communication path 7, a common processing device 9, and a bus 10. An input signal including a voice signal to be stored and a PB signal indicating a control signal, which is input from the voice line 7 to the voice line corresponding unit 8, is converted into a PCM code by the voice code decoding circuit 82 and then sent to the PB receiver 81. are sequentially stored in the audio data buffer 83 via a delay circuit 84 having a delay time corresponding to the time required to detect the PB signal from the input signal (for example, 40 milliseconds). At the same time, when the PB receiver 81 detects a PB signal included in the input signal, it stores it in the PB signal buffer 85 . On the other hand, the control signal register 86 stores PB signals corresponding to various control signals sent by the subscriber 3.
Comparison circuit 87 compares the PB signal stored in PB signal buffer 85 with the PB signal stored in control signal register 86, and if the former matches any of the latter, transmits a detection signal to delay circuit 84. Upon receiving the detection signal, the delay circuit 84 stops transmitting the PCM encoded input signal to the audio data buffer 83. The delay time of the delay circuit 84 is
If it is set equal to the detection time of the PB signal (control signal) by the PB receiver 81, comparison circuit 87, etc.,
The control signal detected from the input signal is removed and stored in the audio data buffer 83. Therefore, for example, when the subscriber 3 who is on a call sends out a predetermined control signal PB signal in order to temporarily suspend the accumulation of voice signals, the PB signal is detected by the above-mentioned process.
The input signals after the control signal are no longer stored in the audio data buffer 83. Also, when the subscriber 3 sends a PB signal as a control signal indicating the end of audio signal storage, storage of input signals subsequent to the control signal is blocked in a similar process.

除去は通話路対応部８により実施され、処理装置
９に負担を掛けることは無い。 As is clear from the above explanation, according to this embodiment, the control signal register 86 stores in advance the
When the PB signal is included in the input signal and is input, the communication channel correspondence section 8 detects the PB signal, removes it from the input signal, and stores it in the audio signal storage file 6. Therefore, only the audio signals to be stored are stored in the audio signal storage file 6, and the subscriber 3 who plays back and listens to the audio signal later is freed from the discomfort caused by the mixing of PB signals. However, the above-mentioned detection and removal of the PB signal is performed by the communication path handling section 8, and does not place any burden on the processing device 9.

ものに限定されぬことは言う迄も無い。 It should be noted that FIG. 3 is merely one embodiment of the present invention, and for example, the control signals to be removed from the input signal are not limited to those illustrated, and any control signal stored in advance in the control signal register 86 may be used. However, the effects of the present invention remain the same. Note that setting a control signal from the processing device 9 in the control signal register may also be considered. Furthermore, the removal of the control signal from the input signal is not limited to the one using the delay circuit 84, and many other modifications can be considered, such as controlling the address of the audio data buffer 83, for example.
In either case, the effects of the present invention remain the same. Furthermore, the audio code decoding circuit 82 is not limited to converting an audio signal (in analog format) into a PCM code, and many other modifications may be considered, but the effects of the present invention will not be affected in any case. It doesn't change. Also subscriber 3
The control signal sent from the control signal is not limited to the PB signal, and the effects of the present invention do not change even when any other multi-frequency signal within the audio band is used. Furthermore, it goes without saying that the configurations of the audio signal storage device and audio signal control device that are the subject of the present invention are not limited to those shown in the drawings.
