title: Android API for analyzing PCM data?
body: <p>Is there an Android-native API which would help me analyzing raw PCM data?  </p>
  
  <p>(Just basic things: frequency, volume of a data piece.)</p>
  
  <p>If not, are there good (non-Android-specific) references to reading PCM?</p>
  
  <p>Thank you!</p>
