Abstract

This paper explores the history that led to modern day DSP and Audio Compression. The roots of modern digital audio sprang from Dudley's 1928 VOCODER, and the WWII era SIGSALY speech scrambler. We highlight these key inventions, detail their hardware and block diagrams, describe how they functioned, and illustrate their relationship to modern day DSP and compression algorithms.
