Music Speed Changer allows you to change the speed of audio files on your device in real time without affecting the pitch (time stretch) or change the pitch without changing the speed (pitch shift). Alternatively, both tempo and pitch may be adjusted together with a single control. The player is a music looper as well - you can slow down song speed and loop sections of the music for easy practice.
The simple to use audio editor is integrated into a music player with playlists, playing queue, preamp, blance, equalizer, and effects. You can use Music Speed Changer to create new tracks or use it as a real time audio manipulation tool, on-the-go correction tool, and as a music learning aide. It is a musician's and music lovers' complete all in one pocket tool and music player.
As a learning tool, the app helps you slow down and loop difficult parts and raise or lower the pitch of any music to suit your range. Alterations can be saved to a new audio track. The editor features A/B repeat looping, key and BPM detection, and the ability to bookmark parts of tracks by setting markers. These learning tools make the app useful for students and teachers of music, dance, language, and academic subjects.
The app's real-time editor is fully integrated into the music player with the ability to affect its playlists and queue. This means you can play your entire music collection with an upbeat tempo for working out and running or slow down and reverb a selection of your music collection for relaxing. The included audio effects help you create new and interesting soundscapes for taking nightcore and slowed + reverb to the next level.
The Pro version of the app comes with automatic formant shift for natural voice tone correction and independent formant shift controls for creating audio effects.

Perfect for what it does, a subtle big though, while song is playing if you change repeat mode from single track to repeat all or play through playlist, whatever, the playing song will be interrupted for a split second which is perceptible and it gets annoying very fast. If this is ironed out it is already perfect.
Fantastic app, but desperately needs layout space optimization!

Music Speed Changer is hands-down one of the best tools available—getting a high-quality 5-stem track splitter for free is amazing. However, the current "Custom Editor Mode" suffers from heavy vertical scrolling on mobile screens. When you expand the Track Splitter to adjust individual stems, it pushes everything out of view.My suggestion to the developer: Please replace permanently or let us replace the traditional seek bar with the waveform permanently at the bottom of the player. Swiping the waveform is a much faster and more precise way to navigate a track than using the tiny seek bar slider anyway! Combining them would save a massive amount of vertical space. If the vertical padding of the control cards could also be shrunk slightly, we could easily fit Tempo, Pitch, A-B Loop, and Track Isolation all on one screen without annoying scrolling. Please optimize the UI real estate! A Detailed email was also sent. Please consider this request.
I love this app but I would love it more if you'll add sleep timer into it.

I'm always a fan of this app, but I would like tell the developers one major thing that is missing and its the sleep timer mode, please add it soon.
Latest update bug
Visshva R
This latest update has a bug where I cannot get back to main menu after opening a song to edit. Pls add swipe gestures to back to main menu just like other apps. It’s annoying to click on the line multiple times where it does not go back to main menu.
Bug fixes and performance improvements.
