<p>pvs2tab —
Copies spectral data to t-variables.
</p>
</div>
<div class="refsect1" title="Description">
<a id="idp39440424"></a>
<h2>Description</h2>
<p>
Copies a pvs frame to a t-variable. Currently only AMP+FREQ and AMP+PHASE formats allowed. This opcode requires the t-type to be defined, which means it only works in the new bison/flex-based parser.

<h2>Syntax</h2>
<pre class="synopsis">kframe <span class="command"><strong>pvs2tab</strong></span> tvar, fsig</pre>
</div>
<div class="refsect1" title="Performance">
<a id="idp39451648"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>kframe</em></span> -- current copied frame number. It can be used to detect when a new frame has been copied.
</p>
<p>
<span class="emphasis"><em>tvar</em></span> -- t-variable containing the output. It is produced at every k-period, but may not contain a new frame, pvs frames are produced at their own frame rate that is independent of kr. Generally, this vector needs to be big enough to contain the frame samples, i.e. N+2 (N is the dft size). If smaller, only a portion of the frame will be copied; if bigger, unused points will exist at higher indexes.
</p>
<p>
<span class="emphasis"><em>fsig</em></span> -- input fsig to be copied.
</p>
<p>
<span class="emphasis"><em>iwinsize</em></span> -- size of the analysis window, defaults to <span class="emphasis"><em>isize</em></span>.
