The timestamp makes it possible to accurately know how much time passed between two recordings made consecutively on the same physical recording device. [[Korg]] portable recorders [[Korg MR-1|MR-1]], [[Korg MR-2|MR-2]], [[Korg MR-1000|MR-1000]] and [[Korg MR-2000s|MR-2000s]] support WSD alongside other DSD based formats.<ref>{{Citation
