AES New York 2009 Starts Friday!

Phil Ramone

AES New York starts this Friday and is jam-packed with technical sessions and every type of audio gear you can imagine. We're also pleased to announce that Sunday night our Heyser lecture will be given by the legendary Phil Ramone. This event is open to all badge colors so make sure to arrive early and get a good seat.

You should also browse through the rest of our extensive technical program calendar and then register for your badge with the advance registration discount before we close registration later today. (If you read this message too late then you can still pay on-site.)

Best Practices in Network Audio (White Paper)

White Paper

Analog audio needs a separate physical circuit for each channel. Each microphone in a studio or on a stage, for example, must have its own circuit back to the mixer. Routing of the signals is inflexible. Digital audio is frequently wired in a similar way to analog. Although several channels can share a single physical circuit (e.g., up to 64 with AES10), thus reducing the number of cores needed in a cable. Routing of signals is still inflexible and any change to the equipment in a location is liable to require new cabling.

Networks allow much more flexibility. Any piece of equipment plugged into the network is able to communicate with any other. However, installers of audio networks need to be aware of a number of issues that affect audio signals but are not important for data networks and are not addressed by current IT networking technologies such as IP. This white paper examines these issues and provides guidance to installers and users that can help them build successful networked systems.

New Tutorial on Large Room Acoustics


The latest in our series of online tutorials continues with 'Large Room Acoustics', given by our forthcoming president, Diemer de Vries. In this detailed educational offering, containing numerous animated illustrations, the physical principles of room acoustics are explained. De Vries shows how by measuring or calculating impulse responses along arrays of receiver positions, the temporal and spatial properties of a sound field can be analyzed and understood, as well as how these properties are related to perceptual quality cues. Several models to calculate impulse responses are discussed. Architectural as well as electro-acoustical measures to correct for acoustical shortcomings are proposed. These aspects are illustrated with examples from practice.

These tutorials are currently only available for viewing by members online and cannot be downloaded for offline viewing.
