33 RPM 1.1.8 :: Control your media Download

In the past, a musician would learn a piece of music by adjusting the speed of their record player and then methodically practice along with the slower version of the song. 33 RPM brings a little back from a time of LPs and record players, just without the scratches.

33 RPM is an excellent tool to transcribe music, by leveraging the power of QuickTime to provide an easy way to slow down, speed up, and loop your media — all without changing the pitch of the music. But if you enjoy those chipmunk-like voices, 33 RPM also has you covered with independent controls to alter the pitch and speed of your audio.

Built for the Mac
