Bose Car Audio

Presented by Jeff Vautin and Joe McCabe of Bose Automative Systems

On Monday, January 21st, Jeff Vautin (PAT Graduate) and Joe McCabe from Bose’s Automotive Systems division visited the University of Michigan chapter of AES to give a presentation about designing acoustic system for vehicles. A car is one of the harshest acoustic environments for an audio system; it has simultaneously very reflective and very dry material, and the small space introduces harmful standing waves. Mr. Vautin and Mr. McCabe talked about the techniques Bose uses to get around these challenges to produce the best audio quality possible, ranging from optimal speaker placement to the different digital signal processing methods used for different speakers throughout the car.


Digital Signal Processing: Daniela Marquez

Daniela will give an overview of audio signal processing on the SigmaDSP IC chip from Analog Devices. The talk will focus on effects processing and how the IC is programmed. Demonstrations will be included in this discussion.

Daniela Marquez graduated from the University of Michigan in 2006 with a double major in Electrical Engineering and Sound Engineering (PAT-D). Currently she works at Analog Devices Inc. as a Software Systems Engineer in the Digital Audio Group. Daniela has been working on algorithm development for the audio processing IC: SigmaDSP. Her current projects include Automatic Room Equalization and Effects Processing.
