title: Library for samplerate conversion of audio data?
body: <p>What is a good Delphi library for samplerate conversion of audio data? I don't mind paying for something. </p>
  
  <p>I need to upsample and download sample audio in realtime. I understand the theory but don't want to write my own routines. </p>
  
  <p>EDIT: Bonus points for something with Mac support. </p>
