Music Speed Changer (MSC) slows music down — or speeds it up — without changing the pitch, and shifts pitch without changing the speed. It’s the practice tool for musicians learning songs by ear and for language learners working through fast speech.
Load a track or a video, set an A/B loop over the tricky part, slow it to a tempo you can actually follow, and play it round and round until it sticks.

Features
Learn by ear
Change tempo and pitch independently in fine 2-decimal steps. A/B loop any section hands-free, with a smooth crossfade so repeats never click.
Video, not just audio
Open video files and slow them down with the picture kept perfectly in sync — ideal for guitar lessons, dance, transcription and tutorials.
Mark it up
Drop colour-coded markers on the intro, verse, chorus or solo and jump straight to any of them. Loops and markers are saved per song.
Practise out loud
Record yourself playing or singing along, and keep time with the built-in metronome at any tempo.
Shape the sound
A 3-band EQ plus vocal reduction to pull the lead vocal back and hear the backing more clearly.
Your library
Import audio and video from your device or Music library, organise everything into playlists, and export to WAV, MP3, M4A or FLAC.
Pro unlocks
Precise 2-decimal tempo and pitch control, unlimited markers, recording, export, EQ, vocal reduction, advanced playlists and an ad-free experience.
