Music Speed Changer Pro
Change music pitch and tempo
Free · In‑App Purchases
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.
