You can remove the vocal of a song, make a song faster or slower, and change the key of a song with this app. The app is good for performers who cannot find the right music for their key, want a faster or slower version of the music, or cannot find the music of a song with no vocals. And for others, it is just HILARIOUS to hear your favorite song in a different tempo or key. Two simple steps in the app: 1. Select a song from your iTunes library 2. After the song is processed, you can then turn on and off vocals with the switch, change the speed and the pitch of the song with the sliders. Dirac Time Stretch/Pitch Shift technology is licensed from the DSP Dimension / Stephan M. Bernsee. This is a free version of Music Factory - Change key, change tempo and remove vocal.
