Soundlith: Slowed + Reverb

Add a song from your files, tap a mode, press play. Slowed + reverb, true 8D, bass boost — and you can save the result as an MP3.

A song you already own, turned into something else. Slow it down, flood it with reverb, send it spinning around your head — one tap, and music you have heard a hundred times sounds new.

HOW IT WORKS

1. Add a track from your files — MP3, M4A, WAV or FLAC
2. Pick a mode
3. Press play. The sound changes instantly.

No account. No sign-up. Works offline.

TRUE 8D — BINAURAL HRTF Binaural HRTF processing sends the sound along a real orbit around your head. Not a left-right pan — a space that flows from ear to ear. Headphones recommended.

SLOWED + REVERB, DONE RIGHT The original technique behind the classic edits: pure resampling drops the pitch together with the tempo, naturally, with zero time-stretch artifacts. Reverb ranges from an intimate room to a cathedral.

17 MODES, ONE TAP EACH • Slowed + Reverb, Deep Slowed, Vaporwave • 8D, Deep Orbit, Void • Bass Boost, Heavy Lifting, Phonk • Sped Up, Nightcore • Dreamy, Lo-Fi, Midnight, Concert, Next Room • Original — the untouched track, always one swipe away

MODE FORGE — BUILD YOUR OWN SOUND Four gestures shape motion, tone, space and weight. Save the result as your own signature and pin it to a track, so it comes back every time that song plays.

SAVE IT AS AN MP3 Render exactly what you are hearing and keep the file on your phone.

SLEEP RITUAL The song slows imperceptibly, the reverb widens, rain rises, and it ends in silence. Set it and put the phone down.
