Sirens' Chor vs SlowSolo

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

Hear a solo you want to learn, but you have no audio file to import? Hold your iPhone to the speaker, record it, and practise it slowly. - Record from a speaker with one tap - Automatic mastering evens out the sound of a phone recording and reduces hiss between notes - High-quality slow-down from 50 % to 100 % without changing the pitch - Repeat a phrase: set Start and End, drag the markers on the waveform, fine-tune by 10 ms - Speed and loop are remembered for every recording - Keeps playing with the screen locked; play/pause from the lock screen and AirPods - Share the slowed-down audio - Everything happens on your iPhone. No account, no ads, nothing is uploaded. Only record audio you have the right to use for your own practice.
