|
<p>Linear interpolating wavetable lookup oscillator with frequency and phase modulation inputs.
|
||
|
|
<p>This oscillator requires a buffer to be filled with a wavetable format signal. This preprocesses the Signal into a form which can be used efficiently by the Oscillator. The buffer size must be a power of 2.
|
||
|
|
<p>This can be achieved by creating a Buffer object and sending it one of the "b_gen" messages ( <a href="./../Classes/Buffer.html#-sine1">Buffer: -sine1</a>, <a href="./../Classes/Buffer.html#-sine2">Buffer: -sine2</a>, <a href="./../Classes/Buffer.html#-sine3">Buffer: -sine3</a> ) with the wavetable flag set to true.
|
||
|
|
<p>This can also be achieved by creating a <a href="./../Classes/Signal.html">Signal</a> object and sending it the 'asWavetable' message, thereby creating a Wavetable object in the required format. Then, the wavetable data may be transmitted to the server using the <a href="./../Classes/Buffer.html#*sendCollection">Buffer: *sendCollection</a> or <a href="./../Classes/Buffer.html#*loadCollection">Buffer: *loadCollection</a> methods.<h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
