title: Change voice/pitch while recording audio
body: <p>I am using the <a href="http://developer.android.com/reference/android/media/AudioRecord.html" rel="nofollow">AudioRecord</a> class to record an user's voice through mic. Is there anyway to change the voice or <code>pitch</code> of the user during the recording in progress. If there is no such way, how can I modulate the output audio file and alter its <code>pitch</code> and save the file back. I don't need the solution to alter the pitch while playing the audio. Thanks in advance.</p>
