Multi Channel Sound

In the Digital Bauhaus Lab (DBL) you would be able to work with a multi channel sound system, the work station uses an audio interface "Fireface 800" and Totalmix FX software for mixing and recording.

The following tutorial will explain you how the hardware is setup and a quick introduction to the software and possible ways that you could expand the capacity of the multi channel sound-card and system.

Types of Multi Channel Audio

There are three different types of speakers arrangements: first the most common one the stereophonic sound or two channel audio, surround sound or more than two channels and ambisonics or full sphere surround sound.

In this tutorial we only are going to cover briefly the surround sound arrangement.

Surround Sound

"Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (center, [front] left, and [front] right) originating only from the listener's forward arc.

Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and presents a fixed or forward perspective of the sound field to the listener at this location. The technique enhances the perception of sound spatialization by exploiting sound localization; a listener's ability to identify the location or origin of a detected sound in direction and distance. Typically this is achieved by using multiple discrete audio channels routed to an array of loudspeakers." taken from wikipedia.

If you want a deeper understanding of Multi channel sound systems, give it a look to the following link Multi-Channel Music & Cinema Systems Theory and Design

Speakers Arrangement

The DBL has a setup of 8 speakers that you will see at the following images:
