Recording PCM audio data to an audio device from native code

Can I write PCM samples to an Android audio device directly from my own code? I was able to play PCM samples by sending data to a socket and playing with AudioTrack. Is it possible to avoid all this path to an audio device by contacting your own code directly? Thank!

Yes, you can try using your audio devices directly. Access works through the nodes of the Linux virtual device hosted in / dev /.

On my HTC Desire it will be

/dev/msm_pcm_out

, . , node . , , .

, "cat"

su


cat /dev/urandom > /dev/msm_pcm_out

. cat C, .
