MuSA_RT applies music analysis algorithms rooted in Elaine Chew’s Spiral Array model of tonality, which also provides the 3D geometry for the visualization space. The app analyzes the audio signal received from a microphone to determine pitch names, maintain short term and longterm tonal context trackers, each a Center of Effect (CE), and compute the closest triads (3-note chords) and keys as the music unfolds in performance. The 3D view presents a graphical representations of these tonal entities in context, smoothly rotating the virtual camera to provide an unobstructed view of the current information. These graphics can also be visualized in an experimental Augmented Reality mode on compatible devices.

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.
