i have written a code which records voice using audiorecord and at the same times it plays that recorded sound using AudioTrack. the main portion of the code is following - AudioRecord audioRecord = new AudioRecord( MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, 16 * 1024); audioRecord.startRecording(); AudioTrack audioPlayer = new AudioTrack(AudioManager.STREAM_VOICE_CALL, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, 16 * 1024, AudioTrack.MODE_STREAM); audioPlayer.play(); for (int i = 0; i < 500; i++) { int n = audioRecord.read(recordBuffer, 0, 160); audioPlayer.write(recordBuffer, 0, n); } ........... This code works perfectly in other device . but in galaxy y , its creating problem. in galaxy y its showing obtainbuffer timed out in audiotrack. i run this code successfully in other devices. and i also checkhed that if i write the recorded sou

I'm struggling to get things right using AudioRecord. Basically what I'm trying to do is seldomly record from the audio on my Android device. I don't have to get a continuous stream of bytes from the audio source, but I have to feed a buffer every 5 minutes or so. The problem is that the memory used by my program increases everytime I'm recording (I used the DDMS to investigate my memory issue). I reduced my code to the following lines to better understand the issue. buffersizebytes = AudioRecord.getMinBufferSize(SAMPPERSEC, channelConfiguration, audioEncoding); tabbAudioBuffer = new byte[buffersizebytes]; setContentView(R.layout.main); audioRecord = new AudioRecord( android.media.MediaRecorder.AudioSource.MIC, SAMPPERSEC, channelConfiguration, audioEncoding, buffersizebytes); int i=1000; while(i-->0) { audioRecord.startRecording(); audioRecord.stop(); } audioRecord.release();
