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.

I use this app to play music for a dance class as it allows me to instantly slow down or speed up the music to a useful tempo. The app has access to all the tracks in the Music app, but not to the playlists. The specialty music I use is from CDs so I own it and it all shows up in the lists as ‘unlocked’. Music that is streamed is locked and has some use restrictions. Other features I use regularly are making playlists, controlling the volume through the app, and setting markers in the music. I really love the fact that you can completely configure the interface to display only the functions you want in the order you want and even the color you want. This allows me to set up an uncluttered interface to display side by side with the dance instructions (in landscape mode). My wishlist for the developer is to import playlists from Music, as I plan my classes on my laptop and download them on the iPad - as it is now I have to find all the tracks again to rebuild the playlist. It would also be nice for the waveform zoom to have a setting to show the whole track - this way one glance would tell you where you are (more easily than the playback slider which looks like the volume and tempo sliders).
