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

VV17 turns your iPhone and iPad into a real-time vocal studio — auto-tune, harmony, and vocoder in one app. Sing or speak into your device and VV17 corrects your pitch to any key and scale as you go. Turn on harmony and it stacks up to four in-key voices under your lead, TC-Helicon style. Switch to Vocode mode and play a MIDI keyboard to drive the tuning by hand — your lead locks to the nearest held note while the others become live harmonies. FEATURES • Real-time auto-tune with adjustable correction amount and speed, from natural to hard-tuned • Automatic diatonic harmonies — stacked in-key thirds, 1 to 4 voices • Infinite mode swaps the harmony stack for a shimmering harmonic series • Vocode mode: control the tuner live from held MIDI notes • Classic vocoder / talkbox synth layer driven by your voice • Choose your key and scale, or explore just-intonation temperaments • Vocal FX: spread, humanize, sibilance, and response controls • Presets to get you started, including lush choir and modern hard-tune rigs • Works standalone or as an Audio Unit (AUv3) plugin inside GarageBand, AUM, Cubasis, and other hosts All processing happens on your device. No account, no sign-up, no data collection.
