SlowDancer: Slow Practice

Hear it slower. Learn it right.

SlowDancer is a high-quality speed player for practicing music, instruments, and languages. Slow a track down without wrecking its pitch, so even fast phrases and tricky pronunciation become clear enough to follow.

· 7-band EQ — boost or cut a specific instrument or vocal
· Pro metronome — beats, subdivisions and trainers
· Mic recording — record yourself playing/singing over the track
· 11 visualizers — see the sound
