iPad Screenshots


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

- Extreme pitch and tempo changes (for instance 24 semi-tones, which is quite a lot!) can lead to noise.
- Voice reduction quality depends on the input. It works best with little compressed music and assumes that voice was recorded in mono and later mixed into the stereo channels (which is the case for a lot of music recordings)

Good but with a problem

I was using this to change a song’s bpm from 98 to 147 but it imports to documents directory and you need iTunes file sharing in order to use it instead of you know SHARING IT DIRECTLY TO FILES!!!!

Works great, no instructions needed

I use this app to slow down foreign language practice material. You can keep the natural pitch of the voice while slowing the tempo up to 90%. But 50% is more than sufficient.

Very nicely thought out interface. Import your audio, select the region, and set a loop if you wish. Then you can speed things up or slow things down to your heart's content.

A well-realized app, worth the 4 bucks.

Not ready for prime time

I thought Apple screened apps before putting them in ITunes Store, but this one is not even ready for beta. The interface is nearly incomprehensible, clicking the website link for help doesn't work because the URL was mistyped. I typed in the correct URL and found a video, but it is for an iPhone version that looks different. Once I got the app to sort of work, playback quality was poor, and when I tried switching to another app, the program bugged out (so you can't reliably play your track in the background). Integration with the music on my Ipad is also clunky. You need to import tracks. All in all, a waste of money and time.
