Multi-layered Cepstrum for Instantaneous Frequency Estimation
We propose the multi-layered cepstrum (MLC) method to estimate multiple
fundamental frequencies (MF0) of a signal under challenging contamination such
as high-pass filter noise. Taking the operation of cepstrum (i.e., Fourier
transform, filtering, and nonlinear activation) recursively, MLC is shown as an
efficient method to enhance MF0 saliency in a step-by-step manner. Evaluation
on a real-world polyphonic music dataset under both normal and low-fidelity
conditions demonstrates the potential of MLC.Comment: In 2018 6th IEEE Global Conference on Signal and Information
