## What is Splitonic?

Splitonic is an AUv3 audio unit for iOS and macOS. It is a filter based on the Fourier spectrum of the input signal and can be used to split the sound in a harmonic and a percussive component. Ideal for remixing when no separate stems are available.

Features:
- AUv3 Plugin for iOS & macOS.
- Spectrogram decomposition: Splits an audio signal into controllable pitched and transient energy layers.
- Real time processing: Low-latency controllable by the user.
- Kernel dimensions: Adjustable horizontal (time) and vertical (frequency) median filter sizes.
- Separation threshold: Configurable threshold to trade off separation isolation against musical artifacts.
- Three-Way Separation: Isolates an additional "residual" or noise component to capture background hiss, vocals, or applause.
- Preset system: with factory and user presets, plus import/export.
- Demo mode available: purchase to unlock full version.
- Optimized layout: for portrait and landscape orientations.
