title: Converting PCM to AMR-WB using AmrInputStream
body: <p>My Android application needs to convert recorded audio in WAV to AMR-NB and AMR-WB.
  And i am done with converting to <strong>AMR-NB</strong> using <strong>AmrInputStream</strong>.</p>
  
  <p>In AmrInputStream, the value for SAMPLES_PER_FRAME is hard coded to <strong>8000 * 20 / 1000</strong>  and the audio has no changes even after changing SAMPLES_PER_FRAME to <strong>(16000*20/1000)</strong>.</p>
  
  <p>Is it possible to convert PCM to <strong>AMR-WB (16 khz)</strong> using AmrInputStream ?</p>
