|
|
|
||
|
|
Bounces sound between two outputs… Like a ping-pong ball. PingPong is
|
||
|
|
actually a compound built upon link::Classes/RecordBuf:: and
|
||
|
|
link::Classes/PlayBuf:: .

@section{argument}
|
||
|
|
bufnum
|
||
|
|
First index of a multi channel buffer.
|
||
|
|
|
||
|
|
@section{argument}
|
||
|
|
inputs
|
||
|
|
An array of audio inputs, the same size as your buffer.
|
||
|
|
|
||
|
|
@section{argument}
|
||
|
|
delayTime
|
||
|
|
Delay time in seconds.
|
||
|
|
|
||
|
|
@section{argument}
|
||
|
|
feedback
|
||
|
|
Feedback coefficient.
|
||
|
|
|
||
|
|
@section{argument}
|
||
|
|
rotate
|
||
|
|
|
||
|
|
Which rotates the inputArray by one step. (left → right, right →
|
||
|
|
left). Rotation of 0 (or 2) would result in no rotation to the
|
||
|
|
inputArray.
