title: sound record tickling / ticks / noises / spikes
body: <p>I successfully record sound on an Android 2.3.4 device (full settings are: <code>AudioSource.MIC</code> + <code>44100Hz</code> + <code>AudioFormat.CHANNEL_IN_MONO</code> + <code>AudioFormat.ENCODING_PCM_16BIT</code>).</p>
  
  <p>I also properly write the PCM data to a WAV file.</p>
  
  <p>The problem is that there are those noises which makes the recording terrible.</p>
  
  <p>The <strong><a href="http://www.sendspace.com/file/dp4niw" rel="nofollow">attached file</a> shows exactly what I mean</strong>. Notice the obvious spikes.</p>
  
  <p><strong>I have tested the same</strong> recording (the music in the attached file) <strong>with some sound recording apps on the market, and they record in a perfect way</strong>, without noises at all - how is it done? Is it a setting I should set (I use <code>AudioRecord</code>)? Should I manually filter those noises with some algorithm? What should I be looking for?</p>
  
  <p>If the attached file is not downloading for some reason or link is simply broken just let me know with a comment.</p>
  
  <p>Thanks!</p>
