Math
Basic utilities for performing mathematical operations over various input signals.
el.in
Identity function, f(x) = x.
Can also be used for accepting an input signal from the audio driver, whereupon
the channel prop will be used to decide which incoming signal channel will be passed forward.
This same feature can also be used for selecting one of N children, for example:
el.in({channel: 2}, w, x, y, z); // Equivalent to `y`Props
| Name | Default | Type | Description |
|---|---|---|---|
| channel | 0 | Number | Selects which input channel to forward |
