This is a software demo. This Mac software allows you to play a song or music or audio track and reduce its speed without affecting the pitch. Select a guitar riff or chord sequence, loop it, and speed up or slow down that loop so it runs faster or slower, without changing the pitch. The program has some sound editing functionality, like EQ, but is mainly a tool for changing a recording's speed. Import a track from iTunes, or directly from a CD, adjust the speed, apply the optional equalizer tool, change the track's musical key, and then save and export to a variety of formats.
