Harmonic Sound Source Separation using FIR Comb Filters.
A technique for separating harmonic sound sources using FIR comb filters is presented. First, a pre-processing task is performed by a multipitch estimator to detect the pitches that the signal is composed of. Then, a method based on the Short Time Fourier Transform (STFT) is utilized to iteratively extract the harmonics belonging to a given source by using FIR comb filters.
The presented approach improves upon existing sinusoidal model approaches in terms of the perceptual quality of the extracted signal.
