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.

Nailed Electric Mistress

I am loving this app so far…I was trying to find an Electric Mistress type of sound and this app nailed it with a little tweaking. It also has the ability to do most other flange type sounds well with Flange 1-3. The only thing I would like to see if the ability to save presets. I don’t see a way to save them and I bumped one of the factory presets in Camelot Pro and erased all my work.
