Technobabble: Synchronous polyphasic temporal compression for the coherent transsubstantiation of the phase-modulated frequency spectrum into a cross-dimensional, entropy-resistant acoustic singularity... to put it in simple terms: a baryonic resonance oscillation with fractal phase inversion that deconstructs the continuous time vector within the Hilbert space, freezing it inside an infinite, dimensionless audio event horizon. JAX Kryostatic is an AudioUnit (AUv3). AudioUnits require an audio host application. We produce audio tools exclusively for Apple platforms. The audio effect processor freezes your audio stream in real time. At the heart of its visualization lies an energy correlometer, alongside a dual stereo FFT waterfall display with adjustable flow speed. Using a "Touch and Slide" interface, you can intuitively freeze and shift the live stream's spectrum, visibly - even into extreme ranges. The freezing effect itself is automatic or freely adjustable, ranging from "Soft Iced" to "Hard Iced." So JAX Kryostatic serves equally well as a creative tool for sound design or simply as a musical analysis utility. This AudioUnit is highly optimized for real-time audio processing and very low CPU usage, as its entire graphical visualization is de-coupled and calculated / rendered directly on the GPU. Our new concept involves releasing some of our fully produced songs alongside our FRONTIER SERIES Audio Units. In doing so, we aim to illustrate our new guiding principle: providing musical tools rather than chasing obscure trends of noise production.

BitDecay
This creative audio effect simulates the character of aging hardware, unstable digital systems, and worn media. It introduces dynamic instability and evolving imperfections to transform pristine audio into lo-fi textures, degraded samplers, or entirely new sound design landscapes.
- Creative digital degradation processor
- Bit crushing and sample rate reduction
- Dynamic instability and clock imperfections
- Musical tone shaping
- Progressive signal erosion controls
- AUv3 support
- Single-page interface

Some digital processors sound broken. Bit Decay sounds like they're breaking. Bit Decay is a creative degradation effect that recreates the character of aging hardware, unstable clocks, failing digital systems, worn media, and collapsing fidelity. Instead of simply reducing bit depth and sample rate, Bit Decay introduces movement, instability, and evolving imperfections that bring static digital destruction to life. Shape classic lo-fi textures, degraded samplers, damaged tape transfers, corrupted audio artifacts, and entirely new sound design landscapes. From subtle vintage coloration to complete digital collapse, Bit Decay gives you precise control over how pristine audio slowly falls apart. Whether you're producing electronic music, processing drums, designing cinematic textures, mangling synths, or adding character to vocals, Bit Decay delivers degradation with personality. Features • Creative digital degradation processor • Bit crushing and sample rate reduction • Dynamic instability and clock-style imperfections • Musical tone shaping • Progressive signal erosion controls • AUv3 support for iPad and Mac hosts • Fast workflow with a simple single-page interface
