Haas effect is a micro-delay applied to either the left or right channel of audio (but not both). This simple effect creates a realistic and natural-sounding increase in the width of the stereo field that still sounds good when mixed back to mono. It is the most simple and effective way to take a mono input and make it sound like stereo. But Haas effect has some problems. First, it can create phase cancellation problems in the bass frequencies, causing them to loose volume. Second, it can sound a bit artificial at high frequencies. This multi-band Haas effect plugin is a simple way to get the stereo width you need in the midrange frequencies without loosing the impact of the bass or making the treble sound phasey. You select any number from one to four bands, each with its own separate Haas delay setting and adjustable crossover frequencies. This makes mono audio sound wide and spacious while preserving the original tone and spectrum transparently.

TfxReverb is a reverb effect AudioUnit Extension plugin. It uses algorithm to generate digital reverb sound. TfxReverb is designed for simple and easy operation. When auto size mode is enabled, number of parameters can be controlled by a single dial to adjust size of the reverb sound, which can be synced to tempo. It features delay lines which are inspired by BBD (bucket brigade device). 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 unit. Features AudioUnit Extension - Input lowpass filter: From 1KHz to 20KHz - Input high-pass filter: From 20Hz to 500Hz - LFO Frequency: From 0.01Hz to 10Hz - LFO Intensity: From 0.0 to 1.0 - Pre Delay: From 1ms to 100ms - Size: From 0% to 100% - Auto size mode: On / Off - Decay: From 0% to 100% - Damp: From 0% to 100% - Output Lowpass Filter: From 1KHz to 20KHz - Early/Late Mix: From 0% to 100% - Dry/Wet Mix: From 0% to 100% - Tempo Sync: On / Off - Tempo (manual) : From 1bpm to 999bpm - Effect Switch: On / Off Host Application Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.
