derived from <a class="el" href="classaflibAudio.html">aflibAudio</a> so that it can be put in a chain. It allows the user to display a power meter (ie signal strength) or a spectrum display. The number of elements in the spectrum display is changeable. The user can have either or both at the same time. It also provides the ability to change the number of updates that occur. It also supports more than one channel. <p><hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="aflibAudioSpectrum::aflibAudioSpectrum"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> aflibAudioSpectrum::aflibAudioSpectrum </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top"><a class="el" href="classaflibAudio.html">aflibAudio</a> & </td> <td class="mdname1" valign="top" nowrap> <em>audio</em> </td> <td class="md" valign="top">) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Constuctor with an audio parent.<p>This will setup for 4 responses per second and 16 samples with 1 channel.
