Neon Engine

Experience your music in high-fidelity neon. Studio-grade slowed and reverb effects, on-device privacy, and a reactive visualizer for the ultimate late-night aesthetic

Transform your audio into a late-night atmosphere. Neon Engine is a precision audio utility designed specifically for the slowed and reverb community.

Whether you’re into City Pop, Synthwave, or Lo-fi, Neon Engine gives you the tools to reshape your local music library into a deep, immersive experience. No cloud processing, no data tracking—just pure, on-device audio engineering.

-- KEY FEATURES --

Precision Slowed Engine: Professional-grade time-stretching that keeps your audio crystal clear, even at ultra-low speeds.

Atmospheric Reverb: A high-fidelity reverb algorithm tuned for "Cathedral" and "Studio" space simulations.

Reactive Neon Visualizer: Watch your music breathe. The UI pulses and tints in real-time based on your track’s frequency data.

Local-First Privacy: We don't want your data. All audio processing is handled entirely on your device’s hardware.

Files Integration: Easily import your own tracks directly from the iOS Files app.

-- WHY NEON ENGINE? --

Most "slowed" tools distort the sound or upload your files to a server. Neon Engine uses the power of your iPhone’s silicon to provide smooth, artifact-free processing locally. It’s a dedicated space for those who appreciate the aesthetic side of music.

Note: Neon Engine is designed for local audio files you own. We respect the artist and the craft—all processing is for personal, creative use.
