Inherits cinder::audio::GenNode.
Noise generator.
- Note
- The frequency parameter is ignored.
Used to specifiy how the corresponding channels are to be resolved between two connected Node's, based on either a Node's input (the default), it's output, or specified by user.
Enumerator |
---|
SPECIFIED |
Number of channels has been specified by user or is non-settable.
|
MATCHES_INPUT |
This Node matches it's channels with it's input.
|
MATCHES_OUTPUT |
This Node matches it's channels with it's output.
