Music Speed Changer Pro

About this app

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. ``` ### What's New [4000] (v1.0) ``` First release of Music Speed Changer. • Independent tempo and pitch control • A/B looping with smooth crossfade • Synced video playback • Per-song markers, playlists and library • Record-along, metronome, 3-band EQ and vocal reduction • Import from your device and Music library; export to WAV/MP3/M4A/FLAC Thanks for trying MSC — tell us what you'd like to see next at audiospeedchanger.com. ##### Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.audiospeedchanger.com/privacy
