About

Wavefolder

This app applies wavefolding, a technique used in modular synthesis and experimental music to add unique character and texture to sound. It differs from simple clipping by preserving amplitude information through a folding process.

Highlights
  • Wavefolding synthesis technique
  • Adds character and aggression to sound
  • Preserves amplitude information
  • Experimental music production tool
  • Modular synthesis application

Wavefolding is widely used in modular synthesis and experimental music production to add character, aggression, or shimmer to sound sources. Unlike simple hard clipping, which crushes transients, wavefolding preserves amplitude information by folding back on itself.

About

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.

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
Read full description

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
