[android-developers] Re: Audio Playback while Recording... ------- attemp playback while recording, cheat it! ----- error
Can you just do the following?
byte []buf = new byte[1024];
int read = 0;
ar = new AudioRecord();
at = new AudioTrack();
do {
//Read from mic
read = ar.read(buf);
//Send to speaker
at.write(buf,0,read);
} while(...);

Thanks Roman,
But my scenario is quiet different from what is discussed in that
blog. I am trying to capture audio from mic directly in pcm format
using AudioRecord interface and also at the same time trying to play
the pcm samples (from different source) to the speaker using the
AudioTrack interface. That is when I am getting this error ---
attemp playback while recording, cheat it! - .
Please let me know if you find any other thread?
Thanks,
Vishal Gaonkar

Hello,
I have a Java application where in I am trying to read Audio samples
from the mic into a buffer and then write the samples back to speaker
from a buffer for playing.
I have used AudioRecord and AudioTrack interfaces. Below are my
configurations for the Record and Track object creation. AudioTrack(0,
8000, 2, 2, playBufSize, 1); AudioRecord(1, 8000, 2, 2, recBufSize);
Using AudioRecord interface I am able to read the samples from mic
continiously (8000 sampling rate and 640 samples per read). In the
similar way I am also able to write some pcm samples to the speaker
from a buffer and play it continuously using the AudioTrack interface
(without record).
But when I try to do both record and play simultaneously I am able to
only record audio from mic but I am not able to play any samples to
speaker. I am getting this error --- attemp playback while
recording, cheat it! - in the log cat.
I have given the following permissions
android.permission.RECORD_AUDIO and
android.permission.MODIFY_AUDIO_SETTINGS in the Manifest file. I
didn't find any special permission to play the audio.
Is there anything else that I need to enable?
Thanks in advance,
Vishal
