Music Speed Changer - Slouly

Slow it down. Speed it up. Make it yours.

Slow it down. Speed it up. Make it yours.

Slouly changes the tempo, pitch and sound of any song on your iPhone. Slow a track right down and it still sounds like music, because the pitch stays where it was.

WHAT YOU CAN DO:

• Slow a song down to learn a part, or speed it up to practise at tempo
• Shift the pitch to match your voice or your instrument
• Add room reverb for depth and space
• Boost the bass, and choose the frequency it works on: 60, 80, 120 or 200 Hz
• Turn on Pan Speed for an 8D effect that moves the sound around you
• Export as Apple Lossless, ready to share anywhere

HOW YOUR MUSIC GETS IN:

1. Share a song or a video to Slouly from any app, including Photos.
2. Or import from Files, or pull the audio out of a video you already have.
3. Slouly keeps the title, artist and artwork, so your library stays tidy.

PRESETS:

Save a combination of tempo, pitch, reverb, bass and pan as a preset, then bring it back with a tap. Rename, reorder and delete them as your setup changes, so the settings you use every day are always one tap away.

EXPORTS THAT STAY ORGANISED:

Every export keeps the original song's tags, with Slouly credited. The filename carries the values you used, and an export that would overwrite an earlier one is numbered instead. Synced lyrics are rescaled to the new tempo and the BPM tag is scaled to match, so the file still lines up wherever you play it.

BUILT FOR:

• Musicians learning a part at a slower tempo
• Singers matching a track to their range
• Dancers and DJs setting the speed they need
• Anyone who wants a song to sound the way they like
