Periodic signal extraction with frequency-selective amplitude modulation and global time-warping for music signal decomposition
2008
2008 IEEE 10th Workshop on Multimedia Signal Processing
A key building block in music transcription and indexing operations is the decomposition of music signals into notes. We model a note signal as a periodic signal with (slow) frequency-selective amplitude modulation and global time warping. Time-varying frequency-selective amplitude modulation allows the various harmonics of the periodic signal to decay at different speeds. Time-warping allows for some limited global frequency modulation. The bandlimited variation of the frequency-selective
