W28 - Practical Techniques for Recording Ambience in Surround

Helmut Wittek, SCHOEPS GmbH - Karlsruhe, Germany
Michael Williams, Sounds of Scotland - Le Perreux sur Marne, France

In this workshop microphone recording techniques for ambience in 5.1 Surround are presented and discussed in theory and practice. Various simultaneous recordings were done in preparation of the workshop.
Theses audio samples from 6 different techniques in 5 different venues are perfectly suitable for demonstrating the principal differences between the techniques and the perceptual consequences on immersion, localization, sound color, stability, etc. The differences are not only valid for ambience and for 5.1 Surround as they show the basic differences between level/time difference stereophony and as they confirm theories on correlation between channels and their consequence for the perceived spatial image.

During the workshop, the audio samples are compared in an A/B manner and differences are discussed. The audio samples as well as the full documentation can be downloaded for free use on They are particularly useful in education but also for sound engineers which have to choose an ambience setup in practice.
