In this paper, we propose a multi-scale model for beat tracking based on the Wave-U-Net model. The proposed model learns multi-scale features by repeatedly resampling feature maps via a series of downsampling blocks and upsampling blocks. With the U-shape structure, we observe that global features a…
We propose a music structure analysis method that converts a path-enhanced self-similarity matrix (SSM) into a block-enhanced SSM using non-negative matrix factor 2-D deconvolution (NMF2D). With a non-negative constraint, the deconvolution intuitively corresponds to the repeated stripes in the path-…
We investigate piano acoustics and compare the theoretical temporal decay of individual partials to recordings of real-world piano notes from the RWC Music Database. We first describe the theory behind double decay and beats, known phenomena caused by the interaction between strings and soundboard.…
