A Journey into Music and Sound Part II: Matlab IDE and wavread

This video is part two of a series that looks at music and sound from a mathematical, science, and engineering point of view using Matlab. In this specific edition I discuss the Matlab development environment and using Matlab to extract data from a .wav file.

Introduction to Wavelets and Filter Banks

Although the history of filter banks and wavelets has been brief, they have had a large impact on signal and image processing. Filter banks, which came first, are used for a number of different audio (1D), images (2D), and video (2D frames changed 30 times every second for interlaced video) applications. Filtering is a linear …
