DOWNLOAD EBOOKThe application of digital signal processing (DSP) to problems in audio has been an area of growing importance since the pioneering DSP work of the 1960s and 70s. In the 1980s, DSP micro-chips became sufficiently powerful to handle the complex processing operations required for sound restoration in real-time, or close to real-time. This led to the first commer cially available restoration systems, with companies such as CEDAR Audio Ltd. in the UK and Sonic Solutions in the US selling dedicated systems world-wide to recording studios, broadcasting companies, media archives and film studios. Vast amounts of important audio material, ranging from historic recordings of the last century to relatively recent recordings on analogue or even digital tape media, were noise-reduced and re-released on CD for the increasingly quality-conscious music enthusiast. Indeed, the first restorations were a revelation in that clicks, crackles and hiss could for the first time be almost completely eliminated from recordings which might otherwise be un-releasable in CD format. Until recently, however, digital audio processing has required high-powered computational engines which were only available to large institutions who could afford to use the sophisticated digital remastering technology. With the advent of compact disc and other digital audio formats, followed by the increased accessibility of home computing, digital audio processing is now available to anyone who owns a PC with sound card, and will be of increasing importance, in association with digital video, as the multimedia revolution continues into the next millennium.

DOWNLOAD EBOOKKarlheinz Brandenburg and Mark Kahrs With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth limited speech processing. Today, the main appli cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research. The topics covered here coincide with the topics covered in the biannual work shop on “Applications of Signal Processing to Audio and Acoustics”. This event is sponsored by the IEEE Signal Processing Society (Technical Committee on Audio and Electroacoustics) and takes place at Mohonk Mountain House in New Paltz, New York. A short overview of each chapter will illustrate the wide variety of technical material presented in the chapters of this book. John Beerends: Perceptual Measurement Techniques. The advent of perceptual measurement techniques is a byproduct of the advent of digital coding for both speech and high quality audio signals. Traditional measurement schemes are bad estimates for the subjective quality after digital coding/decoding. Listening tests are subject to sta tistical uncertainties and the basic question of repeatability in a different environment.

DOWNLOAD EBOOKBringing sampling to a new generation of audio engineers and composers Audio Sampling explains how to record and create sampled instruments in a software setting. There are many things that go into creating a sampled instrument and many things that can go wrong, this book is a step by step guide through the process, from introducing sampling, where it begins to recording editing and using samples, providing much sought after detailed information on the actual process of sampling, creating sampled instruments as well as the different ways they can be used. The software used is the NN-XT a sampler that is a part of the Reason studio software and ProTools LE, however the material discussed is applicable and can be used with any sampler. The companion website has exclusive material including a comprehensive comparison of the different hardware software available, as well as audio examples and video clips from each stage of the process

DOWNLOAD EBOOKThis book is concerned with the processing of signals that have been sam pled and digitized. The fundamental theory behind Digital Signal Process ing has been in existence for decades and has extensive applications to the fields of speech and data communications, biomedical engineering, acous tics, sonar, radar, seismology, oil exploration, instrumentation and audio signal processing to name but a few [87]. The term "Digital Signal Processing", in its broadest sense, could apply to any operation carried out on a finite set of measurements for whatever purpose. A book on signal processing would usually contain detailed de scriptions of the standard mathematical machinery often used to describe signals. It would also motivate an approach to real world problems based on concepts and results developed in linear systems theory, that make use of some rather interesting properties of the time and frequency domain representations of signals. While this book assumes some familiarity with traditional methods the emphasis is altogether quite different. The aim is to describe general methods for carrying out optimal signal processing.
