<h2>Performance</h2>
<p>
Returns the sampling-rate of a <a class="link" href="GEN01.html" title="GEN01"><em class="citetitle">GEN01</em></a> generated table. The sampling-rate is determined from the header of the original file. If the original file has no header or the table was not created by these GEN01, <span class="emphasis"><em>ftsr</em></span> returns 0. New in Csound version 3.49.
