title: AudioQueue trimming and buffer size
body: <p>Even though the application works as expected, I am getting a message in the console that I'd like to understand in more detail.</p>
  
  <p>The setup is as follows. An AVAudioPlayer is created and an .m4a file (03:22 in length and 618 KB in size) is loaded. The file has a bit rate of 23 kbps. I realize that the bit rate is very low, but this is acceptable for the application.</p>
  
  <p>Whenever, I adjust the audio player's currentTime property, I get the following message logged to the console.</p>
  
  <blockquote>
    <p>AudioQueue: request to trim 2112 + 0 = 2112 frames from buffer
    containing 1024 frames</p>
  </blockquote>
  
  <p>The result of setting the currentTime property is as expected, but I wonder what this message means exactly and what I can do to prevent it from showing up.</p>
