Speech Audio Signal Processing

When Speech and Audio Signal Processing published in 1999, it stood out from its competition in its breadth of coverage andits accessible, intutiont-based style. This book was aimed atindividual students and engineers excited about the broad span ofaudio processing and curious to understand the availabletechniques. Since then, with the advent of the iPod in 2001, the field of digital audio and music has exploded, leading to amuch greater interest in the technical aspects of audioprocessing.

This Second Edition will update and revise the originalbook to augment it with new material describing both the enablingtechnologies of digital music distribution (most significantly theMP3) and a range of exciting new research areas in automatic musiccontent processing (such as automatic transcription, musicsimilarity, etc.) that have emerged in the past five years, drivenby the digital music revolution.

New chapter topics include:

• Psychoacoustic Audio Coding, describing MP3 and relatedaudio coding schemes based on psychoacoustic masking ofquantization noise
• Music Transcription, including automatically derivingnotes, beats, and chords from music signals.
• Music Information Retrieval, primarily focusing onaudio-based genre classification, artist/style identification, andsimilarity estimation.
• Audio Source Separation, including multi-microphonebeamforming, blind source separation, and the perception-inspiredtechniques usually referred to as Computational Auditory SceneAnalysis (CASA).
