The rapid development in various fields of Digital Audio Effects, or DAFX, has led to new algorithms and this second edition of the popular book, DAFX: Digital Audio Effects has been updated throughout to reflect progress in the field. It maintains a unique approach to DAFX with a lecture-style introduction into the basics of effect processing. Each effect description begins with the presentation of the physical and acoustical phenomena, an explanation of the signal processing techniques to achieve the effect, followed by a discussion of musical applications and the control of effect parameters. Topics covered include: filters and delays, modulators and demodulators, nonlinear processing, spatial effects, time-segment processing, time-frequency processing, source-filter processing, spectral processing, time and frequency warping musical signals. Updates to the second edition include: Three completely new chapters devoted to the major research areas of: Virtual Analog Effects, Automatic Mixing and Sound Source Separation, authored by leading researchers in the field .Improved presentation of the basic concepts and explanation of the related technology.Extended coverage of the MATLABTM scripts which demonstrate the implementation of the basic concepts into software programs.Companion website (http://www.dafx.de/) which serves as the download source for MATLABTM scripts, will be updated to reflect the new material in the book.Discussing DAFX from both an introductory and advanced level, the book systematically introduces the reader to digital signal processing concepts, how they can be applied to sound and their use in musical effects. This makes the book suitable for a range of professionals including those working in audio engineering, as well as researchers and engineers involved in the area of digital signal processing along with students on multimedia related courses.

Digital Audio Signal Processing The fully revised new edition of the popular textbook, featuring additional MATLAB exercises and new algorithms for processing digital audio signals Digital Audio Signal Processing (DASP) techniques are used in a variety of applications, ranging from audio streaming and computer-generated music to real-time signal processing and virtual sound processing. Digital Audio Signal Processing provides clear and accessible coverage of the fundamental principles and practical applications of digital audio processing and coding. Throughout the book, the authors explain a wide range of basic audio processing techniques and highlight new directions for automatic tuning of different algorithms and discuss state- of-the-art DASP approaches. Now in its third edition, this popular guide is fully updated with the latest signal processing algorithms for audio processing. Entirely new chapters cover nonlinear processing, Machine Learning (ML) for audio applications, distortion, soft/hard clipping, overdrive, equalizers and delay effects, sampling and reconstruction, and more. Covers the fundamentals of quantization, filters, dynamic range control, room simulation, sampling rate conversion, and audio codingDescribes DASP techniques, their theoretical foundations, and their practical applicationsDiscusses modern studio technology, digital transmission systems, storage media, and home entertainment audio componentsFeatures a new introductory chapter and extensively revised content throughoutProvides updated application examples and computer-based activities supported with MATLAB exercises and interactive JavaScript applets via an author-hosted companion websiteBalancing essential concepts and technological topics, Digital Audio Signal Processing, Third Edition remains the ideal textbook for advanced music technology and engineering students in audio signal processing courses. It is also an invaluable reference for audio engineers, hardware and software developers, and researchers in both academia and industry.

Die digitale Audiosignalverarbeitung wird zur Aufnahme und Speicherung von Musik­ und Sprachsignalen, zur Tonmischung und Produktion digitaler Tonträger, zur digi­ talen Übertragung zum Rundfunkempfänger und in Consumergeräten wie CD, DAT und PC eingesetzt. Hierbei befindet sich das Audiosignal direkt nach dem Mikrofon bis hin zur Lautsprecherbox in digitaler Form, so dass eine Echtzeit-Verarbeitung mit schnellen digitalen Signalprozessoren durchgeführt werden kann. Das vorliegende Buch ist Grundlage einer Vorlesung Digitale Audiosignalverarbei­ tung, die ich seit 1992 an der Technischen Universität Hamburg-Harburg für höhere Se­ mester halte. Es wendet sich an Studenten der Ingenieurwissenschaften, Informatik und Physik, aber auch an den Praktiker in der Industrie, der sich mit Aufgaben der Audio­ signalverarbeitung in den Bereichen Studiotechnik, Consumer-Elektronik und Multi­ media beschäftigt. Es werden die mathematischen und systemtheoretischen Grundlagen der digitalen Audiosignalverarbeitung behandelt und die typischen Anwendungen im Hinblick auf Realisierungsaspekte diskutiert. Vorausgesetzt werden Kenntnisse in der Systemtheorie, der digitalen Signalverarbeitung und der Multiraten-Signalverarbeitung.
