Audioclip
Easily load and play (over and over again if you like) all or part of short(ish) audio files in the browser.
Uses the Web Audio API when available (which supports precise play length and multiple instances of the same sound playing at once), otherwise falls back to HTML5 <audio> tags. If those aren't available either (Internet Explorer 8 and below, basically), a graceful degradation to silence occurs.
API
var clip = url; // Load the clip clip; // Play entire clip clip; // Play clip from start time to end clip; // Play clip from start time to start time + duration
