How to extract the audio strength/magnitude?
<p>In an android app I have text data which is spoken using android's built in Text to speech engine.
On my activity Now I am putting a little indicator whose colour intensity should change to indicate voice being spoken.</p>

<p>For this simple visualization I want to extract audio magnitude/amplitude as per spoken data and transform it to color intensity of the indicator to indicate voice being spoken by the app.</p>

<p>Can someone please advise me on this ?</p>

<p>Thanks</p>
