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.
VariSpeed
This app simulates a classic tape echo machine, replicating the functionality of a specific vintage hardware unit. It allows for variable delay times by altering the speed of the tape mechanism.
- Classic tape echo simulation

Please note: this is an AUv3 plugin that can be used with compatible host Apps. GSi VariSpeed is a simulation of the WEM Copicat IC-400 Belt Drive VariSpeed model, the first tape echo machine made by WEM with a DC capstan motor capable of changing speed, thus varying the delay time. GSi VariSpeed replicates the hardware instrument “as is” with all its pros and cons, without any additional feature. This can be considered as the second chapter of a tribute to the genius of Mr. Charlie Watkins that GSi began back in 2008 with the release of the freeware "WatKat", which was a simulation of the "Custom Copicat".
