<h2>Description</h2>
<p>
Creates an ftable with values of the sone function for equal power.

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>f</strong></span> # time size "sone" start end equalpoint rescale</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="id3750434"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>size</em></span> -- number of points in the table. Must
be a power of 2 or power-of-2 plus 1 (see <a class="link" href="f.html" title="f Statement (or Function Table Statement)"><em class="citetitle">f statement</em></a>).
</p>
<p>
<span class="emphasis"><em>start, end</em></span> -- first and last value to be stored. The points stored are uniformly spaced between these to the table size.
</p>
<p>
<span class="emphasis"><em>equalpoint</em></span> -- the point on the curve when the input and output values are equal.
</p>
<p>
<span class="emphasis"><em>rescale</em></span> -- if not zero the table is not rescaled
</p>
<p>
The table is filled with the function x*POWER(x/eqlp,
FL(33.0)/FL(78.0)) for x between the start and end points. This
is the Sone loudness curve.
</p>

<div class="refsect1" title="Examples">
<a id="id3751370"></a>
<h2>Examples</h2>
<p>
Here is a simple example of the <span class="emphasis"><em>GENsone</em></span> routine. It uses the
file <a class="ulink" href="examples/gensone.csd" target="_top"><em class="citetitle">gensone.csd</em></a>.
It will generate a simple sone shaped output wave.
