A frequency-domain convolution UGen using a fixed kernel which can be updated
by a trigger signal. The delay caused by the convolution when the kernel is a
dirac impulse is equal to frameSize - controlBlockSize , so for a frameSize
of 2048 and a control-block size of 64, this is 1984 sample frames.
- Value Params
- 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
- kernel
buffer identifier for the fixed kernel, which may be modulated in combination with the trigger. Even a trigger input of zero is used, upon UGen initialization the kernel must point to a valid buffer, otherwise the UGen aborts.
- trig
updates the kernel on a change from non-positive to positive (<= 0 to >0)
