Bleass Reverb (ESD); reverb plugin; algorithmic reverb with adjustable room size and decay time; low-pass filter in the effect path for reducing high frequencies; pre-delay for delaying the onset of the reverb; LFO for modulating reverb reflections with variable rate and depth; freeze function for holding the current reflections; transform function with frequency shifter for real-time sound morphing along X and Y axes; integrated ducker with adjustable threshold, attack and release; multi-mode input filter with high-pass or low-shelving; graphical display for filter, modulation and ducker; efficient DSP engine with low CPU load
