Splitonic

Spectral Remix Filter (AUv3)

Free · In-App Purchases

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.
