In this comprehensive guide Eddy Bøgh Brixen will take you through the complex and confusing concept of audio metering, giving you the knowledge and skills you need to utilize optional signal levels and produce high quality audio.
Covering all areas of this essential topic, Audio Metering begins with the basics- audio definitions and digital techniques, and works up to hearing and psychoacoustics. Levels in audio are defined, and the metering standards and practices are discussed, covering the existing standards abs VU and PPM, as well as the new loudness metering standards, making this the reference guide to audio metering.
This new edition includes
* Current information on loudness metering, covering existing and new standards, defining terms like LU, RLB, and LKFS
