Sirens' Chor vs milliVerb

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

Carry the venue in your pocket. milliVerb turns your iPhone or iPad into a responsive, performance-ready reverb processor for musicians, vocalists, and sound explorers. Send live microphone audio through rich, fully wet algorithmic spaces that you can shape while you perform. DESIGNED TO BE PLAYED • Shape size, decay time, pre-delay, diffusion, damping, tone, and filtering in real time • Explore studio rooms, chambers, concert halls, churches, and expansive atmospheric spaces • Sculpt low-, mid-, and high-frequency decay directly over the live spectrum • Add movement using multiple modulation styles, adjustable depth and rate, tempo sync, or incoming MIDI clock • Use envelope and ducking controls to make the reverb respond dynamically to your performance • Control parameters and step through presets using MIDI CC and compatible foot controllers • Unlock custom presets, favorites, and performance sets with the full version . SEE YOUR REVERB The real-time spectral display provides an animated view of the processed reverb tail. Turn your device sideways for an expanded panoramic visualization, or use the interactive decay-band editor to shape frequency-dependent reverb behavior directly over the spectrum. BUILT FOR LIVE SOUND Keep input, output, and the live spectrum visible while you perform. Input compression helps manage incoming dynamics, while Apple Voice AEC, advanced adaptive feedback cancellation, optional dynamic protection, and venue calibration help reduce feedback in challenging acoustic environments. MADE FOR CONTINUOUS USE The full version can keep milliVerb processing during rehearsals and performances with optional background and locked-screen audio. You can also prevent the screen from automatically locking while the reverb is running. TRY IT FREE Practice with milliVerb in free 60-second audition sessions. A one-time in-app purchase unlocks uninterrupted live processing, background audio, custom presets, favorites, and performance sets.
