Unifying Local and Global Methods for Harmonic-Percussive Source Separation

James Brown and the Famous Flames - I Got You (I Feel Good)
This excerpt is taken from a 1964 recording of this well-known song and has a duration of 7 seconds. The instrumental break section happens from 00:41 to 00:48 and features a repeated alto saxophone lick played by Maceo Parker over a four-bar drum beat played by his brother Melvin Parker.
Our proposed method delivers better separation than the comparison methods but has problems to capture the ride cymbal. Better preservation of the ride cymbal is only possible in the oracle case, when score-informed hard constraints are applied to the NMF activations.
