final case class GrainBuf(numChannels: Int = 1, trig: GE, dur: GE = 1.0f, buf: GE, speed: GE = 1.0f, pos: GE = 0.0f, interp: GE = 2, pan: GE = 0.0f, envBuf: GE = -1, maxGrains: GE = 512) extends MultiOut with AudioRated with IsIndividual with Product with Serializable
A granular synthesis UGen taking sound stored in a buffer. Another buffer can be used to provide an amplitude envelope. The input sound buffer must be monophonic, but output may be multi-channel, using a panorama control.
All arguments except numChannels and maxGrain are polled at grain creation
(trigger) time.
- numChannels
the number of channels to output. If
1, a monophonic signal is returned and thepanargument is ignored.- trig
a control- or audio-rate trigger to start a new grain. For audio-rate, timing is sample frame accurate.
- dur
grain duration in seconds
- buf
buffer holding a mono audio signal portions of which are read as grains
- speed
playback speed of the grain, where
1.0is original rate,0.5is half speed etc.- pos
grain start position, where
0is beginning and1is the end of the input buffer- interp
interpolation type when using pitch-shifting via
speed.1for no interpolation (nearest sample),2for linear interpolation, and4for cubic interpolation.- pan
panning position when
numChannelsis greater than one. Equivalent to the pan position ofPan2(for stereo output) orPanAz(for more than two channels)- envBuf
identifier of a buffer containing a signal to use for the grain envelope. The default value of
-1means that a built-in Hann envelope is used.- maxGrains
maximum number of overlapping grains that can be used at a given time. This value is set at the UGens init time and cannot be modified later. Lower value mean that less memory is used.
