Preface

What is dynamic range e and how loud is it? These are the eternal questions that concern everyone who works with the practical aspects of sound.

This book was written to give everybody with an interest in audio an explanation of the conditions that determine the answers to these questions.

Fundamental acoustics, electronics and psycho-acoustic concepts are described here. A number of topics related to digital technology are also covered and information can also be obtained here on the majority of the tools that are used in describing the magnitude of sound.

This is the second edition of Audio Metering. The update is particularly concerned with loudness measures and metering. However, the basic chapters in the beginning of the book have been expanded and a complete new chapter on room acoustics has been added.

HOW SHOULD THIS BOOK BE READ?

Audio Metering can be used as a reference book. The beginning contains a table of contents and the end of the book provides a glossary and an index.

Reading the book from cover to cover is highly recommended. The subject matter of the book has been organized so that the most basic material is placed at the beginning, while the more generally descriptive material is found towards the end of the book.

Enjoy
