Record the voice call packets in a file
<p>I want to make an app to record voice call. I have read many relevant articles about it. I am aware that latest Galaxy comes with this feature. But wanted to know a few things:</p>

<ol>
<li>When we use the native AudioRecord::start(), where is the recorded data stored in the File System?</li>
<li>What is the format of the recorded data?</li>
<li>how to access that data to manipulate it?</li>
</ol>

<p>Thanks in advance.</p>
