The Algorithms of Digital Audio: Audio Processing

Abstract

You’ll look at a number of the primary audio editing and “sweetening” effects in the Audacity 2.1 Effect menu. Some of them visualize the concepts that you learned about in the first few chapters of the book. This offers reinforcement of the principles. You will learn how to utilize algorithms that allow you to amplify waveforms, shift the pitch, change the playback speed, equalize the frequency response, and apply audio effects such as reverb and echo (delay). You also learn how to selectively filter frequencies out of your sample waveform by using audio filters such as High Pass, Low Pass, and Notch Filters.
