I've been looking at the Noise Alert code http://bit.ly/aHdbTO to see
how to monitor the amplitude of sound recorded by MediaRecorder.
Noise Alert uses mRecorder.getMaxAmplitude() to determine the maximum
amplitude seen since the last method call.
public double getAmplitude() {
if (mRecorder != null)
return (mRecorder.getMaxAmplitude()/2700.0);
else
return 0;
}
Can someone tell me why the getAmplitude function returns
maxAmplitude()/2700.0? Why does it divide by 2700 specifically?
Thanks!
