        <h2>Performance</h2>
        <p>
      Returns the number of samples loaded into stored function table number <span class="emphasis"><em>x</em></span> by GEN01. This is useful when a sample is shorter than the power-of-two function table that holds it. New in Csound version 3.49.
    </p>
        <p>
      As of Csound version 5.02, <span class="emphasis"><em>nsamp</em></span> works with deferred-length function tables (see
      <a class="link" href="GEN01.html" title="GEN01"><em class="citetitle">GEN01</em></a>).
    </p>
        <p>
      <span class="emphasis"><em>nsamp</em></span> differs from <span class="emphasis"><em>ftlen</em></span> in that <span class="emphasis"><em>nsamp</em></span> gives the number of sample frames loaded, while <span class="emphasis"><em>ftlen</em></span> gives the total number of samples. For example, with a stereo sound file of 10000 samples, ftlen() would return 19999 (i.e. a total of 20000 mono samples, not including a guard point), but nsamp() returns 10000.
