Hi,
For my app, I need to record audio from MIC on an Android phone, and send it over TCP to the other android phone, where it needs to be played.
I am using AudioRecord and AudioTrack class. This works great with a file - write audio to the file using DataOutputStream, and read from it using DataInputStream.
However, if I obtain the same stream from a socket instead of a File, and try writing to it, I get an exception.
I am at a loss to understand what could possibly be going wrong. Any help would be greatly appreciated.
EDIT: The problem is same even if I try with larger buffer sizes (65535 bytes, 160000 bytes).
This is the code:
Recorder:
int bufferSize = AudioRecord.getMinBufferSize(11025, , AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);
AudioRecord recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC, 11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufferSize);
byte[] tempBuffer = new byte[bufferSize];
recordInstance.startRecording();
while (/*isRecording*/) {
bufferRead = recordInstance.read(tempBuffer, 0, bufferSize);
dataOutputStreamInstance.write(tempBuffer);
}
The DataOutputStream above is obtained as:
BufferedOutputStream buff = new BufferedOutputStream(out1); //out1 is the socket's outputStream
DataOutputStream dataOutputStreamInstance = new DataOutputStream (buff);
Could you please have a look, and let me know what is it that I could be doing wrong here?
Thanks,
