Hello Nieldeokar,
Can you tell me how to calculate amplitude from your code ? I have added this code , I am getting Amplitude but not more than 55 in any case
private boolean handleCodecInput(AudioRecord audioRecord,
MediaCodec mediaCodec, ByteBuffer[] codecInputBuffers,
boolean running) throws IOException {
byte[] audioRecordData = new byte[bufferSize];
int length = audioRecord.read(audioRecordData, 0, audioRecordData.length);
computedbAmp(audioRecordData); ///this is amplitude code
if (length == AudioRecord.ERROR_BAD_VALUE ||
length == AudioRecord.ERROR_INVALID_OPERATION ||
length != bufferSize) {

        if (length != bufferSize) {
            if (onRecorderFailedListener != null) {
                Log.d(TAG, "length != BufferSize calling onRecordFailed");
                onRecorderFailedListener.onRecorderFailed();
            }
            return false;
        }
    }

//code
//compute here
public double computedbAmp(byte[] audioData) {
//System.out.println("::::: audioData :::::"+audioData);
double amplitude = 0;
double sum=0;
for (int i = 0; i < audioData.length/2; i++) {
double y = (audioData[i2] | audioData[i2+1] << 8);
sum += yy;
}
double rms = sum / audioData.length/2;
amplitude = 20.0Math.log10(rms/32768.0);

    return amplitude;

}

I would like to integrate the library in my application with a minSdkVersion 16, some tips or recommendations ?
