While it could be mistaken for an audio player, 33 RPM is more the kind of tool you'd use to adjust the speed of a song to your voice or other instruments.
This simple little application lets you play back a song and adjust speed, volume and pitch thanks to sliders. You can also set a loop by entering both an end and a start time. 33 RPM displays song information and you can quickly reach any point in your track thanks to the slider in the main window.
There's not much more you'll be able to do with 33 RPM other than transcribing audio tracks. However the application is clean, and you can close off both the info and controls windows if you want to. 33 RPM can be of great use to test out different rhythms of a song without having to open a more advanced media player.
33 RPM is a very simple application to play around with the volume, speed and pitch of a song.
