A/B Practice Loop Points

Music Speed Changer has AB repeat functionality which allows setting the start point (A) and end point (B) for a section of an audio track to be played back repeatedly. This loop function, commonly called AB, A+B, A-B, or A/B repeat, allows for a track or portion of a track to be continuously looped or repeated. The A/B Repeat is used by musicians, singers, dancers, and other students studying their craft or field of interest by ear or to audio. The AB segment can be slowed to a comfortable speed and slowly increased as the students improve their skills and master the contents of the segment. The A/B can also used to create beats from loops and rhythmic practise backdrops for music practice.
