This is a AUv3 compatible overdrive/distortion which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels. The effect offers the user an incredible variety of control over the sound due to the number of different types of emulation modes and a range of optional filtering and tone controls. We provide an optional a built in compressor to enable you to limit the sound prior to wave shaping. We provide 9 different sounding distortion emulation algorithms, each with unique characteristics and sound. The signal can then be passed through low and high pass filtering to remove harsh or unwanted frequencies such as DC offset or mains hum. We also provide a choice of either pure tone controls or a 3 band +/- 12dB parametric equaliser to have the ultimate control over mid-tones. This effect was designed to give those nice slightly overdriven or crunch sounds but there are some pure all out distortion models too. This is one of a suite of AUv3 compatible plugins which will also soon be available from 4Pockets.
Sirens' Chor
This experimental audio effect app analyzes input audio to generate a secondary harmonic voice using sine wave oscillators. The generated voice can be mixed with the original or played solo, creating a chorus effect. It's CPU intensive and operates within a specific frequency range.
- Harmonic analysis of input audio
- Sine wave oscillator synthesis
- Adjustable chorus effect
- Second voice generation
- AUV3 plugin support

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
