Sirens' Chor vs SimplComp

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

Introduction SimpleComp is very simple general purpose compressor that’s easy to use and very light on CPU. Sometimes you just need some basic dynamics processing that doesn’t add “character”, or that relies on sophisticated techniques or performance expensive DSP. SimplComp was designed for those times! SimpleComp is an AUv3 effects plugin that can run standalone, or in any AUv3 compatible host such as Logic Pro, GarageBand or AUM. SimpleComp currently runs on iPadOS / iOS (iPad & iPhone) and macOS (Intel & Silicon) and is available as a Universal Purchase from the Apple App Store. If you’re planning on using SimpleComp on Mac / desktop, please ensure that your favourite DAW / host supports AUv3 (not just AU). Parameters ACTIVE - toggles the effect on or off. IN - sets the level of the incoming signal. Typically you would leave this as 0dB, i.e unity gain. The meters to the left of the panel show the level of the incoming signal. COMP - sets the compression threshold. Note that unlike many compressor plugins, the threshold is reduced as you turn up the control, so as you turn it up, you get more compression effect. The bar meter below this control will give an indication of how much over the threshold the input signal is. RATIO - sets the compression ratio. A higher ratio results in a more noticeable “squashing” effect on the signal. OUT - sets the level of the output signal. You may need to adjust this is you wish to manually make up the gain lost by the compression effect, e.g. when AUTO is off (see below). ATK - sets the attack time of the compressor. REL - sets the release time of the compressor. AUTO - toggles automatic makes gain. When switched on, SimplComp will automatically adjust the gain to compensate for the gain reduction that occurs when compression is applied. This is calculated using the compression threshold and ratio. MIX - sets the balance between the compressed and original / dry signal. This allows SimplComp to be used for parallel compression. Factory Presets There are a few factory presets included to get you going. The overall compression will be dependent on the level of the input signal so you will need to select an appropriate factory preset as a starting point, then adjust the COMP parameter up or down for more or less compression indicated by the bar meter below the control.
