Sirens' Chor vs Multiband Haas Effect

This one is quite experimental and CPU heavy app! While working on my Chord Detector app I came up with the idea to play the found harmonics with sine wave oscillators so I can hear what the algorithm is hearing :) It turns out to be an interesting output that led me to creation of this audio effect app. What happens here is that the input is analysed for main harmonics in the range of 80Hz to 1500Hz. Then a series of sine wave oscillators are set to play those harmonics with the exact frequency and volume and their output is added to create a second voice. This second voice can then be mixed with the input to create some kind of chorus or played alone. All this is CPU heavy process so it should be used with care... Also to make this effect possible I had to use limited range 80Hz to 1500Hz so it is not suitable for every instrument and you have to keep that range in mind when producing. Some very fast volume and frequency changes are applied to the oscillators. The app is AUV3

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.
