About this app

Music Speed Changer changes audio tempo (speed) and pitch in realtime quick and easy. Just select an audio file, mark the region you want to play (and loop/repeat) and change tempo and pitch on the fly.
It is also possible to export the changed audio file for playback in other players.
Use cases of Music Speed Changer are for instance: practicing guitar and other music instruments, transcriptions, change the speed of audiobooks, language learning...

Features:
- Change pitch and tempo (speed, time-stretch) independently.
- Support for arbitrary pitch (even deviating from semi-tones)
- Loop region
- Select region
- Filtering
- Import various formats including mp3, wav, m4a, ogg, aac, ...
- Export to wav and mp3
- Volume amplification
- Play left/right channels separately (e.g. for duet training)
- Voice/Vocals reduction: reduce vocals so that only music is audible (does not work with all audio recordings!)

Note: Extreme pitch and tempo changes (for instance 24 semi-tones, which is quite a lot!) can lead to noise.

I have loved this app for several years, but it suddenly stopped working. I did get a response from customer service, but I've emailed twice since my last response because I haven't heard back and I need to use it, and no reply. It just suddenly stopped loading files, even though it's been working great for literally years. So, it would have gotten a five except is on the blink. Hopefully it'll be back soon!

A decent app that does as professed. I have three pro versions: iPod, Kindle, Galaxy. Mostly I use the speed adjustment to slow down riffs. I also accelerate rhythm tracks when I nail the riff. Pitch is helpful to play in a different scale. A zoom feature would be nice, but for lack of that, a portion of the song can be saved, then opened. This app is as good as it gets, although I haven't researched alternatives.

This app was the best out there and i had it since 2014 and now this year this month when I started using it on my Samsung Galaxy s10 the music will play and then shut off on lock screen. I never experienced this before, I thought it was my settings on my phone. But if it could be updated to where it was working on and off screen again I will definitely give it a 5 star rating.
