ehDirtDelay has a number of unusual if not novel features:
Outside the feedback loop: - A pre-delay for expanded rhytmic potential. - Two syncable LFOs with per stereo channel phase settings.
In the feedback loop: - Unipolar amplitude modulation, for adding dirt, noise and glitch. - A basic reverb for diffusing the signal or "metalizing" it. - Three choices for overdrive / distortion. - Samplerate / bitdepth reduction.
Convenient signal routing options: - Stereo or mono input. - Mute left or right input. - Swap left and right input. - Feedback stereo balance. - Invert feedback phase.
