Speech and Audio Signal Processing: Processing and Perception of Speech and Music, Second Edition

PART VIII

OTHER APPLICATIONS

The Universe is full of magical things patiently waiting for our wits to grow sharper.

–Bertrand Russell

PARTS VI and VII focused on speech recognition, synthesis, and coding as the primary applications of the engineering methods introduced in this book. These tasks have been the object of study for decades, and they can also be seen as archetypes for a wide range of potential applications. However, there are certainly many more ways to use the technologies discussed here. Part VIII provides introductory information about a few other applications to give a sense of the possibilities.

Digital representations of music audio have become increasingly important in the past decade; Chapter 36 looks at some ways computers can be used to create music signals, then Chapter 37 looks at problems of recognizing individual musical events in audio recordings, and Chapter 38 looks at broader problems of organizing and searching music audio collections.

Music, as with other real-world sound scenes, often consists of multiple acoustic sources, and Chapter 39 looks at some techniques for separating and isolating those sources. Methods developed for the analysis and synthesis of speech and other sounds can be adapted to provide a range of transformations, as described ...
