<h2>Performance</h2>
<p>
Returns the loop segment start-time (in seconds) of stored function table number <span class="emphasis"><em>x</em></span>. This reports the duration of the direct recorded attack and decay parts of a sound sample, prior to its looped segment. Returns zero (and a warning message) if the sample does not contain loop points.
