Book description

Recording Studio Design is essential reading for anyone involved in building, renovating and maintaining recording studios. Good acoustics in a recording studio is crucial to the success of a project, and the financial implications of failure means getting things right first time is essential. In straightforward language Newell covers the key basic principles of acoustics, electro-acoustics and psychoacoustics and their application to studio design. Fully updated to reflect current technology and practice additional sections include digital signal processing, design for soundtrack mixing and foley rooms, providing a complete reference offering real solutions to help improve the success rate of any studio.

*Provides great detail on the practical recording application in various acoustic environments
*Complex issues are explained and real solutions provided
*Benifit from Newell's years of experience, designing over 200 studios including Manor and Town House Studios
