<p class="p1">This behaves similar to <a href="SC://Poll"><span class="s2">Poll</span></a> but displays its output as a textual "VU meter" visualisation (ranging from -60 to 0 dB). The class also automatically inserts an <a href="SC://Amplitude"><span class="s2">Amplitude</span></a> analysis into the chain (you can modify this by supplying a function to the <b>ana</b> argument). Also, internally it ONLY RUNS AT CONTROL RATE, although it can analyse ar or kr inputs (and passes them back out again).</p>
<p class="p3"><br></p>
<p class="p1">Parameters not found in Poll:</p>
<p class="p1"><span class="Apple-tab-span"> </span><b>width</b><span class="Apple-tab-span"> </span>Number of characters used to display the meter. Cannot be modulated.</p>
