8D, Slowed & Reverb: Soundlith

Turn any song on your phone into something new. Slow it down, add reverb, or send it orbiting around your head — one tap and it plays.

HOW IT WORKS
1. Add a track from your files (MP3, M4A, WAV, FLAC)
2. Pick a mode
3. Press play — the sound changes instantly

No account, no sign-up, works offline.

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

REAL 8D
The sound travels a full orbit around your head, not just left to right. Best with headphones.

SLOWED + REVERB
Speed and pitch drop together, the way the classic edits do it. Reverb ranges from a small room to a cathedral.

BUILD YOUR OWN SOUND
Mix lets you shape motion, tone, space and weight yourself. Save the result and pin it to a track so it comes back every time that song plays.

SAVE AS M4A
Render exactly what you are hearing and keep the file on your phone.

SLEEP TIMER
The track slows gradually, the reverb widens, and everything fades into silence.

EVERYTHING STAYS ON YOUR PHONE
All processing happens on the device. Nothing is uploaded and there is no account to create.

PREMIUM
The free version shows ads. Premium unlocks all 18 modes, Mix, M4A export and the sleep timer, and removes ads. If you only want the ads gone, Remove Ads is a one-time purchase.

Soundlith Premium is offered weekly, monthly and every 3 months. It renews automatically and can be cancelled anytime in your Google Play account settings.
