<script type="text/x-red" data-help-name="AudioSynthWaveformSineHires"> <h3>Summary</h3> <div class=tooltipinfo> <p>Create a highly precise, low distortion sine wave signal. Mainly useful for codec & analog circuitry testing.</p> </div> <h3>Audio Connections</h3> <table class=doc align=center cellpadding=3> <tr class=top><th>Port</th><th>Purpose</th></tr> <tr class=odd><td align=center>Out 0</td><td>Sine Wave, upper bits</td></tr> <tr class=odd><td align=center>Out 1</td><td>Sine Wave, lower bits</td></tr> </table> <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> </script> <script type="text/x-red" data-template-name="AudioSynthWaveformSine"> <div class="form-row"> <label for="node-input-name"><i class="fa fa-tag"></i> Name</label> <input type="text" id="node-input-name" placeholder="Name"> </div> </script>
