final case class StereoConvolution2L(rate: Rate, in: GE, kernelL: GE, kernelR: GE, trig: GE = 1, frameSize: GE, fadePeriods: GE = 1) extends MultiOut with IsIndividual with Product with Serializable

A frequency domain stereo convolution UGen, capable of performing linear cross-fades between kernel updates. When receiving a trigger, there is a linear cross-fade between the old kernel the new buffer contents. It operates similar to Convolution2L , however uses two buffers and outputs a stereo signal, resulting in better CPU usage than two discrete instances of Convolution2L as this way one FFT transformation per period is saved.

Warning: This UGen seems currently broken (SC 3.6.3)

in

the realtime input to be convolved

kernelL

buffer identifier for the left channel's fixed kernel, which may be modulated in combination with the trigger

kernelR

buffer identifier for the right channel's fixed kernel, which may be modulated in combination with the trigger

trig

updates the kernel on a change from non-positive to positive (<= 0 to >0), and starts a new cross-fade from the previous kernel to the new one over the given amount of periods.

frameSize

size of the kernel. this must be a power of two. the FFT calculated internally by the UGen has a size of twice this value. The maximum allowed frameSize is 16384. (init-time only)

fadePeriods

fade duration expressed as number of convolved blocks. If the desired duration in seconds is dur , then the number of periods can be calculated as fadePeriods = dur * SampleRate.ir / frameSize . (init-time only)
