<h3>Summary</h3> |
|
|
|
<p>Create a highly precise, low distortion sine wave signal. |
|
|
|
Mainly useful for codec & analog circuitry testing.</p> |

<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 frequency, from 0 to 22000. Very low values may |
|
|
|
be used to create a LFO (Low Frequency Oscillator) for objects |
|
|
|
with modulation signal inputs. |
|
|
|
</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. |
|
|
|
</p> |
|
|
|
<h3>Notes</h3> |
|
|
|
<p>An 11th order Taylor series approximation is used to generate |
|
|
|
a very accurate sine wave. At least the upper 25 bits are believe |
|
|
|
to be perfect. This is mainly intended for testing 24 bit codec chips!</p> |
