Discover 33 RPM

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 leverages 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.


QuickTime logo

Built off of QuickTime technology, 33 RPM can play the same audio and video formats that your QuickTime Player can. If you have optional plug-ins installed, such as Perian or WMV Player, you get the bonus of being able to play Windows Media and Flash files, as well.

33 RPM is all about controlling your media. Changing the speed on a record player would also change the pitch, but not with this program. Independent controls allow you to change either the speed or the pitch without affecting the other settings.

Mac Integration

Universal Binary logo

Mac users expect more out of their programs, so even a clunky inteface can force a person to look for a more Mac-like solution. Since 33 RPM was designed for the Mac, it looks, feels, and acts like a Macintosh application, and not like a program that was ported over from Windows. 33 RPM embraces current Macintosh standards and technologies: QuickTime-compatible playback, automatic updates, ease of use, and a streamlined interface.
