Command Description
!AVAUDIO Play/record audio file (.wav format)
Play an audio file (locally or for both sides of a voice call), or record to an audio file (from the
microphone only, or both sides of a voice call).
Each <operation> type is started and stopped independently. For example, to simultaneously
play a file for both ends of a voice call and record that call to another file:
1.
Start recording to a file and start playing an existing audio file for both ends of the call:
AT!AVAUDIO=4,1,/usr/recording1.wav
AT!AVAUDIO=3,1,/data/outgoing1.wav
2.
When ready to stop playing the outgoing file and recording the call:
AT!AVAUDIO=3,0
AT!AVAUDIO=4,0
Note: Only .wav format audio files are supported.
