The MVSep Guitar model is based on the MDX23C, Mel Roformer and BSRoformer architectures. The model produces high-quality separation of music into a guitar part (including acoustic and electronic) and everything else. The model was compared with the Demucs4HT model (6 stems) on a guitar validation set. The metric used is SDR: the higher the better.
