A digital degradation effect that combines two classic forms of lo-fi distortion: bit depth reduction (quantization) and sample rate reduction (decimation). Together they emulate the character of early digital samplers, 8-bit consoles, and vintage hardware with limited converter resolution. The signal is first quantized to a reduced number of bits, introducing the harsh harmonic distortion known as quantization noise. It is then resampled at a lower effective rate using a sample-and-hold stage, producing aliasing artifacts above the new Nyquist frequency.

SL DREAD blends incoming audio with 30 evolving horror scenes. Process melodies, drum loops, vocals, synths and field recordings to build disturbing atmospheres for music, film and game sound design. Fusion makes the atmosphere respond to the source. Shape its character with Age, Decay, Motion, Voice, Event, Space and Mix, and control drone, breath, whisper and metallic layers independently. Transport Link follows playback in a compatible host. The weathered medical-monitor interface includes an audio-reactive CRT display, scene selection, user presets and input/output controls. On iPhone, compact portrait pages separate Controls, Layers and I/O. Use the full interface in landscape or on iPad. Includes a standalone app and an AUv3 audio effect. To process a track from another music app, insert SL DREAD in a compatible AUv3 host. Standalone input monitoring starts muted to avoid speaker feedback; use headphones when enabling microphone monitoring. No account or in-app purchase is required. Audio processing stays on your device.
