<p>ATSbufread — reads data from and ATS data file and stores it in an internal data table of frequency, amplitude pairs.

<div class="refsect1" title="Description">
<a id="idp13905976"></a>
<h2>Description</h2>
<p>
<span class="emphasis"><em>ATSbufread</em></span> reads data from and ATS data file and stores it in an internal data table of frequency, amplitude pairs.
</p>
</div>
<div class="refsect1" title="Syntax">
<a id="idp13906896"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>ATSbufread</strong></span> ktimepnt, kfmod, iatsfile, ipartials[, ipartialoffset, \
ipartialincr]</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp13910232"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>iatsfile</em></span> – the ATS number (n in ats.n) or the name in quotes of the analysis file made using <a class="ulink" href="http://www-ccrma.stanford.edu/~juan/ATS.html" target="_top"><em class="citetitle">ATS</em></a>.
</p>
<p><span class="emphasis"><em>ipartials</em></span> – number of partials that will be used in the resynthesis (the noise has a maximum of 25 bands)
</p>
<p><span class="emphasis"><em>ipartialoffset</em></span> (optional) – is the first partial used (defaults to 0).
</p>
<p><span class="emphasis"><em>ipartialincr</em></span> (optional) – sets an increment by which these synthesis opcodes counts up from <span class="emphasis"><em>ipartialoffset</em></span> for ibins components in the re-synthesis (defaults to 1).
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp13913504"></a>
<h2>Performance</h2>
<p><span class="emphasis"><em>ktimepnt</em></span> – The time pointer in seconds used to index the ATS file. Used for <span class="emphasis"><em>ATSbufread</em></span> exactly the same as for <a class="link" href="pvoc.html" title="pvoc"><em class="citetitle">pvoc</em></a>.</p>
<p>
<span class="emphasis"><em>kfmod</em></span> – an input for performing pitch transposition or frequency modulation on all of the synthesized partials, if no fm or pitch change is desired then use a 1 for this value.
</p>
<p><span class="emphasis"><em>ATSbufread</em></span> is based on pvbufread by Richard Karpen. <a class="link" href="ATScross.html" title="ATScross"><em class="citetitle">ATScross</em></a>, <a class="link" href="ATSinterpread.html" title="ATSinterpread"><em class="citetitle">ATSinterpread</em></a> and <a class="link" href="ATSpartialtap.html" title="ATSpartialtap"><em class="citetitle">ATSpartialtap</em></a> are all dependent on <span class="emphasis"><em>ATSbufread</em></span> just as <a class="link" href="pvcross.html" title="pvcross"><em class="citetitle">pvcross</em></a> and <a class="link" href="pvinterp.html" title="pvinterp"><em class="citetitle">pvinterp</em></a> are on <a class="link" href="pvbufread.html" title="pvbufread"><em class="citetitle">pvbufread</em></a>. <span class="emphasis"><em>ATSbufread</em></span> reads data from and ATS data file and stores it in an internal data table of frequency, amplitude pairs. The data stored by an <span class="emphasis"><em>ATSbufread</em></span> can only be accessed by other unit generators, and therefore, due to the architecture of Csound, an <span class="emphasis"><em>ATSbufread</em></span> must come before (but not necessarily directly) any dependent unit generator. Besides the fact that <span class="emphasis"><em>ATSbufread</em></span> doesn't output any data directly, it works almost exactly as <a class="link" href="ATSadd.html" title="ATSadd"><em class="citetitle">ATSadd</em></a>. The ugen uses a time pointer (<span class="emphasis"><em>ktimepnt</em></span>) to index the data in time, <span class="emphasis"><em>ipartials</em></span>, <span class="emphasis"><em>ipartialoffset</em></span> and <span class="emphasis"><em>ipartialincr</em></span> to select which partials to store in the table and <span class="emphasis"><em>kfmod</em></span> to scale partials in frequency.
