N2 - In mixtures of musical sounds, the problem of overlapped harmonics poses a significant challenge to source separation. Common Amplitude Modulation (CAM) is one of the most effective methods to resolve this problem. It, however, relies on non-overlapped harmonics from the same note being available. We propose an alternate technique for harmonic envelope estimation, based on Harmonic Temporal Envelope Similarity (HTES). We learn a harmonic envelope model for each instrument from the non-overlapped harmonics of notes of the same instrument, wherever they occur in the recording. This model is used to reconstruct the harmonic envelopes for overlapped harmonics. This allows reconstruction of completely overlapped notes. Experiments show our algorithm performs better than an existing system based on CAM when the harmonics of pitched instruments are strongly overlapped.
