Music Speed Changer Pro

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.

LEARN BY EAR • Change tempo and pitch independently, in fine 2-decimal steps • A/B loop any section and repeat it hands-free • Smooth-loop crossfade so repeats don't click or jump • Choose from three studio-grade stretch engines to match your ear and your device

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, COME BACK TO IT • Drop color-coded markers on the intro, verse, chorus or solo • Jump straight to any marker — your loops and markers are saved per song

PRACTISE OUT LOUD • Record yourself playing or singing along • Built-in metronome to keep time at any tempo

SHAPE THE SOUND • 3-band EQ • Vocal reduction to pull the lead vocal back and hear the backing

YOUR LIBRARY • Import audio and video from your device — or straight from your Music library • Organise everything into playlists, with shuffle and reordering • Export your edits to WAV, MP3, M4A or FLAC • Keeps playing in the background and on the lock screen

Whether you're transcribing a solo, drilling a chord change, learning choreography or slowing down a podcast in a foreign language, MSC gives you full control over speed and pitch.

Free to use with ads. Upgrade to MSC Pro for precise 2-decimal control, unlimited markers, recording, export, EQ, vocal reduction, advanced playlists and an ad-free experience — available as a monthly subscription or a one-time lifetime purchase.
