Hi Prajkti,
Have a look at this link.

int audioSource = MediaRecorder.AudioSource.VOICE_DOWNLINK;
        int sampleRateInHz = 8000;
        int channelConfig = AudioFormat.CHANNEL_CONFIGURATION_MONO;
        int audioFormat = AudioFormat.ENCODING_PCM_16BIT;
        bufferSize = AudioRecord.getMinBufferSize(sampleRateInHz,
                channelConfig, audioFormat);
        AudioRecord recordInstance = new AudioRecord(audioSource,
                sampleRateInHz, channelConfig, audioFormat, bufferSize);
        recordInstance.startRecording();

And then read the buffer in real time to analyze and play with the data.
Something like:

byte buf[] = new byte[bufferSize];
int bytesRead = 0;

bytesRead = recordInstance.read(buf, 0, bufferSize)

Hi Pratik,
I thought it was working but actually, in spite of mentioning the Audio_source as "MediaRecorder.AudioSource.VOICE_DOWNLINK" , it records the MIC data
Have you ever tried this??

Thanks,
