Highlights
  • 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
