For educational purposes I'm trying to understand how audio is routed from/to the radio during a voice call. By running strace on my N1 I was able to see this:
- Audio is played back to the AudioFlinger (i see write() to /dev/msm_pcm_out)
- Recording is not done using msm_pcm_in - maybe DMA directly to the modem?
- Most of the work is done in the propriety libhtc_ril.so
Couldn't find anywhere in the source code where an AudioTrack is created for the voice call.
If anyone could shed some light on this I'd be grateful.
Thanks.

Is there any way to know which speech/voice codec (HR, FR, EFR, AMR...) is used during a phone call?
Also, is there any way to control which codec is used? I remember my old nokia enabled me to toggle between HR and FR.

Hello,
I am trying to programatically play an audio file (WAV) on an Android phone and inject that audio into a phone call so that remote party on the other end of the call can hear that audio. Is there a way to inject audio into a voice all? Likewise, I also need to record downlink voice call audio on the Android phone. This is for an internal project and not for commercial/consumer use.
I read in blogs that some modifications to the kernel would allow such audio inject & record and in another blog, I found commands such as aplay, arec and amix could help. Anyone knows how to do this?
I am open to pay up to $10K for a working solution on Samsung S3.
Thanks.

Have you had any success? I found your posting after googling a similar query and hoping you've had better luck than I.
