## What is Neon Engine?

Transform your music into a sound that feels uniquely yours.
Neon Engine is an on-device audio workshop for reshaping local music with immersive effects. Import a track, preview different styles, fine-tune the result, and save it to your personal library—all directly on your iPhone.

-- AUDIO MODES --
Bass Enhance: Add more weight and depth to your music with a stronger low-end sound.
Slowed + Reverb: Adjust the tempo, tone, and reverb to create a deeper, more atmospheric mix.
City Pop: Give your track a bright, nostalgic character inspired by retro nighttime soundscapes.
Fast Tempo: Speed up your music with adjustable tempo controls, from a subtle lift to a high-energy remix.
Original: Save and manage the original track alongside your converted versions.

-- BUILT FOR YOUR MUSIC --
Live Preview: Hear each effect before saving and fine-tune supported modes in real time.
Personal Library: Organize converted tracks, rename them, filter by effect, and mark favorites for quick access.
Bulk Actions: Select multiple tracks to update favorites or delete them together.
Files Integration: Import compatible audio files directly from the iOS Files app.
Background Playback: Continue listening to tracks from your Neon Engine library outside the app.

-- PRIVATE BY DESIGN --
Your music stays on your device. Audio processing is performed locally without uploading your files to a remote server.
Neon Engine is designed for local audio files you own and for personal, creative use.
