Unlike Serato or Virtual DJ, which often sound thin when pitching tracks up or down drastically, OtsAV employs an advanced form of granular synthesis for its tempo stretching. In version 1.90, the Ots Stereo Isolation (OSI) algorithm was mature. This algorithm attempts to separate the stereo image into "center" (Vocals/Kick) and "sides" (Hi-hats/Pads).
In Serato, when you load a track, it seeks to the cue point. In OtsAV 1.90, by the time you move the crossfader, the NOC deck has already scanned the track, verified the bitrate, and is looped at the intro. This allows for zero-latency hard cuts. For radio jingles or fast-paced club mixing, this feels like cheating—in a good way.
