[0045] see figure 1 , propose the first embodiment of the method of simultaneous conversation and recording of the present invention, said method comprises the following steps:
[0046] Step S101: Collecting sound signals during the call and recording
[0047] The communication terminal is talking and recording at the same time, and the calling event and recording event are events of the same priority. The communication terminal can first start the recording, and during the recording process, it suddenly receives an incoming call, and after the call is established, the recording is transferred to the background to continue; or it can first establish the call, and start the recording during the call. In short, the two are carried out simultaneously without interfering with each other.
[0048] The sound signal collected by the sound collection unit such as a microphone includes a call signal and a recording signal, wherein the call signal is the sound from the user, and the r...

[0056] see figure 2 , propose the second embodiment of the method of simultaneous conversation and recording of the present invention, said method includes the following steps:
[0057] Step S201: Collecting sound signals during calls and recordings
[0058] Step S202: Comparing the volume difference of the sound signals collected by the two sound collection units
[0059] Step S203: Separate the sound signal whose volume difference is smaller than the preset value as the recording signal
[0060] The present invention is especially applicable to the situation where the recording sound source is two meters away from the communication terminal. The volume difference of the sound emitted by the two meters away from the sound source collected by the two sound collection units is usually less than 6 decibels, so the volume difference is directly reduced to less than 6 decibels The sound signal is separated and used as a recording signal.

[0064] see image 3 , propose the third embodiment of the method of simultaneous conversation and recording of the present invention, the method includes the following steps:
[0065] Step S301: Collecting sound signals during the call and recording
[0066] Step S302: Comparing the volume difference of the sound signals collected by the two sound collection units
[0067] Step S303: Separate the sound signal whose volume difference is smaller than the preset value as the recording signal
[0068] Step S304: Separate the sound signal whose volume difference is greater than or equal to the preset value as a call signal
[0069] In this embodiment, the recording signal and the call signal are separated directly by comparing the volume difference of the sound signals collected by the two sound collection units. Wherein, the preset values described in steps S303 and S304 may be the same or different, preferably both are 6 decibels.
