About DEBUSSI: Slow, Reverb, Reverse
DEBUSSI turns any audio file into a slowed + reverb version - the sound of late nights, empty highways, and dimly-lit rooms. Drop in a song. Slow it down. Drown it in reverb. Reverse it. Export it. That's the whole app. — CORE FEATURES • IMPORT - Bring in any audio file from Files (MP3, M4A, WAV, AIFF, CAF, and other DRM-free formats). Two built-in demo tracks are ready to go if you just want to hear it work. • SPEED - Classic varispeed from 0.5× to 2.0×. Pitch follows speed, just like slowing down a record. Slow a song into a syrupy, chopped-and-screwed haze, or speed it up for a real nightcore edit. DEBUSSI Pro adds independent pitch/transpose control, so you can move speed and pitch separately. • REVERB - Three studio-grade presets: Room, Hall, and Cathedral. Dial in the exact amount of space you want. • REVERSE - One tap. Full track reversed. Great for intros, transitions, and finding hidden textures inside your favorite songs. • EXPORT - Bounce to AAC M4A, or lossless WAV with DEBUSSI Pro. Share to Files, Messages, AirDrop, or straight into your DAW. — BUILT FOR • Slowed + reverb creators and edit channels • Sped-up and nightcore edit makers • Phonk, chopped-and-screwed, and Memphis rap fans • Lo-fi and ambient beatmakers • DJs prepping edits and transitions • Anyone who's ever wanted their favorite song to feel a little heavier - or a little faster — DESIGN DEBUSSI is built to disappear. No sprawling menus. No genre presets pretending to be effects. Just the controls that matter, a waveform, and an export button - wrapped in an interface designed to stay out of your way at 2am. — PRIVACY Your audio never leaves your device. No cloud processing. No account required. No tracking pixels. Import a file, edit it, export it - that's it. — DEBUSSI PRO The free version exports AAC M4A up to 30 seconds, plus one full-length export to try it out. DEBUSSI Pro unlocks unlimited-length exports, lossless WAV bounces, and independent pitch/transpose control (change pitch and speed separately). One-time purchase. Not a subscription - nothing renews, nothing recurs. Buy it once and it's yours, on every device signed in to your Apple Account.
