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)'''
- Value Params
- 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 asfadePeriods = dur * SampleRate.ir / frameSize. ''(init-time only)''- 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
frameSizeis 16384. ''(init-time only)''- 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.
