<h3>Summary</h3>
|
|
<div class=tooltipinfo>
|
|
<p>Create a modulated sine wave, using any audio signal to continuously
|
|
modulate the sine wave frequency.</p>
|
|
</div>

<h3>Functions</h3>
|
|
<p class=func><span class=keyword>amplitude</span>(level);</p>
|
|
<p class=desc>Set the amplitude, from 0 to 1.0.
|
|
</p>
|
|
<p class=func><span class=keyword>frequency</span>(freq);</p>
|
|
<p class=desc>Set the center frequency, from 0 to 11000. The output will
|
|
be this center frequency when the input modulation signal is zero.
|
|
Modulation input 1.0 causes the frequency to double, and input -1.0
|
|
causes zero Hz (DC) output. For less modulation, attenuate the input
|
|
signal (perhaps with a mixer object) before it arrives here.
|
|
</p>
|
|
<p class=func><span class=keyword>phase</span>(angle);</p>
|
|
<p class=desc>
|
|
Cause the generated waveform to jump to a specific point within
|
|
its cycle. Angle is from 0 to 360 degrees. When multiple objects
|
|
are configured,
|
|
<a href="http://www.pjrc.com/teensy/td_libs_AudioProcessorUsage.html" target="_blank">AudioNoInterrupts()</a>
|
|
should be used to guarantee all new settings take effect together.
