Left Hand & Right Hand Separation

In the following, we present the a subset (12 of 81) of decomposed and reconstructed right hand (RH) and left hand (LH) parts of the separated piano recordings using Open-Unmix (UMX), Spleeter (SPL), Demucs (DMC), Hybrid Demucs (HDMC), and AudioShake. Additionally, we include the decomposed ground-truth piano recordings from the Piano Concerto Dataset (PCD).

As illustrated in the figure, this subset comprises the top five best-separated examples (PCD IDs: 045, 042, 024, 026, 059), the top five worst-separated examples (PCD IDs: 079, 000, 076, 065, 005), and two averagely separated examples (PCD IDs: 022, 040) by HDMC and AudioShake, based on the resulting SDR scores.
