title: Circular Audio Recording
body: <p>I was wondering if you guys have an solution for this:
  I want to record and hold a Audio buffer of 10 seconds (dosent has to be 10), but only The 10 last recorded seconds!
  Ex. I record for ten seconds, then The first recorded seconds is overwritten and a new One is added to the end!
  My first thougth was a circular buffer where The start pointer just moves along!
  My problem is not The circular buffer, The problem lies With how to handle Audio samples into an buffer! Its a bit tricky for Me to understand! And thougths, or you need further explonation?</p>
  
  <p>(might be bad english, stupid auto correct)</p>
  
  <p>Pre thank you! </p>
