TfxMod is a chorus / flanger effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). The delay line is identical to the delay line of the TfxEcho except its buffer length. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based chorus / flanger unit.
