We propose a new musical audio search method based on audio signal matching that can cope with key and tempo variations. The method employs the self-similarity matrix of an audio signal to represent a key-invariant structure of musical audio. And, we use dynamic programming (DP) matching of self-similarity matrices to deal with time variations. However, conventional DP-based sequence matching methods cannot be directly applied for self-similarity matrices because they cannot treat gaps… CONTINUE READING
