Galaxy Brain is a frequency shifter and delay combo ready to take any sound into outer space. With easy stereo controls, three modulation sources, and optional hardware clipping, things can go intergalactic very quickly. From thick chorus effects to choppy AM textures to space-laser SFX, it's all packed inside. Frequency Shifter - Range settings from 5 Hz to 5 kHz, each with its own character - Direction mixer enables tremolo and ring modulation effects - Modulate shift amount with LFO, envelope follower, and sequencer - Freely mixable modulation sources Stereo Delay - Free or tempo-synced delay time - Continuous ping-pong and LR delay time skew - Tone-shaping filters in the feedback path - Wet signal ducking - Adjustable glide time between delay values, up to 10 seconds Modulation - Stereo LFO with nine waveforms, warp, and swing - Envelope follower with optional sidechain input - Eight-step sequencer - Repeatable Random engine for consistent bounces Optional Hardware Clipping - Add drive and saturation at the output stage - Internal gain compensation for louder output at high settings Core Features - Morph Settings for smooth transitions between two complete configurations - Auto Bypass saves CPU when input is silent - AB settings comparison - HQ mode with 4x oversampling and ADAA - One-click loudness matching - All parameters automatable with precise playback - Light and dark interface modes - Internal undo/redo - Standalone app includes support, manual links and in-app purchase options for license purchase Two-week trial included, one-time purchase for full unlock.

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.
