Audio-Rate Math
|
|
<br>
|
|
<br>
|
|
One of the most powerful features of Tone.js is the ability to
|
|
perform math and logic on audio-rate signal. Signals
|
|
can be ramped and scheduled to control Audio Parameters and
|
|
other Signals making it simple to create elaborate,
|
|
interconnected automations. Additionally, Signals and Signal maths use no
|
|
ScriptProcessorNodes which make them very efficient.
