A Journey into Music and Sound Part III: Playing Music in Reverse and Increasing Volume

This video is part three 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 vectors, playing music in reverse, and increasing the music volume.

A Journey Into Music and Sound Part IV: Speeding Up and Slowing Down Music

This video is part four of a series that looks at music and sound from a mathematical, science, and engineering point of view using Matlab. In this specific I speed up the music (Remember Alvin and the Chipmunks?)  and slowed the music down (“Screw” music).

Sound-level Indicator

In this video, I show the circuit for a simple sound-level indicator and demonstrates how it works. Circuit may be found at http://clydelettsome.com/blog/product/sound-level-indicator-schematics-and-parts-list/

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 …
