About this app

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 speed and pitch may be adjusted together with a single control. The app is a music looper as well - you can slow down song speed and loop sections of the music for easy practice.

You can also save the adjusted audio to an MP3 or WAV audio file for sharing with friends or listening in another player.

Music Speed Changer is great for musicians practicing an instrument needing to slow down the tempo or practice in a different tuning, speeding up audio books for faster listening, making nightcore or just rocking out to your favorite song at 130%.

Ratings and reviews

Amazing app. Had to change my rating. Setting for bit rate would revert back to 192k even though I changed it to 320k output. After some tweaks, the setting seems to stick for now. There are a lot of features in the settings menu. Not sure why the bit rate kept reverting but as long as the issue doesn't come back, this app is a solid 5 stars. Couple the fact that it can be used as a general audio player along with all the editing features, it's extremely versatile for the file size. Well done!!

I've been using this app for years now! And I can't get enough with it. Although, is it okay if you add an option to turn your new "custom time stretching algorithm" off in the settings? I personally liked the old pitch raising and the new one just sounds jarring to me. Especially after you crank it all the way up to pitch 24. Seriously, it sounds like I'm using the Audacity pitch feature and it kinda bugs me. Can you please make it optional? Thanks :)

First of all, huge props on everything this software does. It's amazing! Every musician I know I tell about this app. Its a staple as far as I'm concerned. Incredible Job! I do have a couple suggestions to improve it though. Actually additions that I think would prove helpful to a lot of users. Particularly musicians. The first would be a 4 or 8 beat count in click that matches the Bpm of the audio file. Just to give you that quick bit of time to get ready after pressing play before the track starts. Second would be an auto advance of the play cursor that automatically detects and cues up to the beginning of the wave form of an audio file. This would be great for those files that have a second or 2 of silence before the track starts. Then working with the count in click you can always start on the first beat of the track when playing along. I don't know if any of these have been suggested before but I really think they'd be handy additions. Thank you!
