Название: An Introduction to Digital Audio
Автор: Watkinson J.
Аннотация: Master the basics from first principles: the physics of sound, principles of hearing etc, then progress onward to fundamental digital principles, conversion, compression and coding and then onto transmission, digital audio workstations, DAT and optical disks. Get up to speed with how digital audio is used within DVD, Digital Audio Broadcasting, networked audio and MPEG transport streams.
All of the key technologies are here: compression, DAT, DAB, DVD, SACD, oversampling, noise shaping and error correction theories are treated in a simple yet accurate form.
Thoroughly researched, totally up-to-date and technically accurate this is the only book you need on the subject.
* Expand your knowledge with this thorough treatment of digital audio for a wide range of disciplines
* Clearly explainations require a minimum of math to allow for easy understanding
* Get up to speed with how digital audio is used within DVD, Digital Audio Broadcasting, networked audio and MPEG transport streams
