<p>vlinseg —
Vectorial envelope generator
</p>
</div>
<div class="refsect1">
<a id="idm281472872413160"></a>
<h2>Description</h2>
<p>
Generate linear vectorial segments
</p>
</div>
<div class="refsect1">
<a id="idm281472872411912"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>vlinseg</strong></span> ifnout, ielements, ifn1, idur1, ifn2 [, idur2, ifn3 [...]]</pre>
</div>
<div class="refsect1">
<a id="idm281472872351240"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ifnout</em></span> - number of table hosting output vectorial signal
</p>
<p>
<span class="emphasis"><em>ifn1</em></span> - starting vector
</p>
<p>
<span class="emphasis"><em>ifn2,ifn3,etc.</em></span> - vector after <span class="emphasis"><em>idurx</em></span> seconds
</p>
<p>
<span class="emphasis"><em>idur1</em></span> - duration in seconds of first segment.
</p>
<p>
<span class="emphasis"><em>idur2, idur3, etc. </em></span> - duration in seconds of subsequent segments.
</p>
<p>
<span class="emphasis"><em>ielements</em></span> - number of elements of vectors.
</p>
</div>
<div class="refsect1">
<a id="idm281472872344872"></a>
<h2>Performance</h2>
<p>
These opcodes are similar to <span class="emphasis"><em>linseg</em></span> and <span class="emphasis"><em>expseg</em></span>, but operate with vectorial signals instead of with scalar signals.
</p>
<p>
Output is a vectorial control signal hosted by <span class="emphasis"><em>ifnout</em></span> (that must be previously allocated), while each break-point of the envelope is actually a vector of values. All break-points must contain the same number of elements (<span class="emphasis"><em>ielements</em></span>).
</p>
<p>
All these operators are designed to be used together with other opcodes that operate with vectorial signals such as <span class="emphasis"><em>vcella</em></span>, <span class="emphasis"><em>adsynt</em></span>, <span class="emphasis"><em>adsynt2</em></span>, etc.
</p>

<h2>Example</h2>
<p>
Here is an example of the vlinseg opcode. It uses the files <a class="ulink" href="examples/vlinseg.csd" target="_top"><em class="citetitle">vlinseg.csd</em></a>.
