Audio Recording in Stereo giving same data in Left and Right channels

Question

I am trying to record and process audio data based on differences in what gets recorded in the left and right channel. For this I am using Audio Record class, with MIC as in

Answer 1

Using this configuration:

private int audioSource = MediaRecorder.AudioSource.MIC;  
private static int sampleRateInHz = 48000;  
private static int channelConfig = AudioFormat.CHANNEL_IN_STEREO;  
private static int audioFormat = AudioFormat.ENCODING_PCM_16BIT;  

The data in the audio data is as follows.

leftChannel data: [0,1],[4,5]...
rightChannel data: [2,3],[6,7]...

So you need to seperate the data.

readSize = audioRecord.read(audioShortData, 0, bufferSizeInBytes);
for(int i = 0; i < readSize/2; i = i + 2)
{
       leftChannelAudioData[i] = audiodata[2*i];
       leftChannelAudioData[i+1] = audiodata[2*i+1]; 
       rightChannelAudioData[i] =  audiodata[2*i+2];
       rightChannelAudioData[i+1] = audiodata[2*i+3];
}

Hope this helpful.
