Wavelet packets as a tool for sound processing
Ronald R. Coifman · The Journal of the Acoustical Society of America · 1995
Wavelet packet analysis of sound corresponds to an optimized musical transcription in which the sound is organized in different structures (orchestration), each of which is described by a ‘‘musical score.’’ This representation is a superposition of wavelet packets (notes) of different duration, pitch, location in time, and amplitude. Fast algorithms permit real-time transcriptions with a minimal number of notes. In this talk we will give a precise definition of these statements as well as applications to audio compression, denoising, recognition, and modeling.
