BLACKSBURG, Va. – An audio engineering technology lab at Virginia Tech has installed two Attero Tech unD32 32-Channel Dante break out boxes to conduct research on immersive audio.
The ASPIRE (Acoustics, Signal Processing, and Immersive Reality) Lab teaches engineering students the fundamental principles used in audio engineering, including microphone and loudspeaker design, digital signal acquisition and processing, filtering, room acoustics, human hearing and high-density loudspeaker array surround sound. The lab is outfitted with 10 PC workstations with Reaper digital audio programs installed. Each PC is connected to a Presonus Studiolive 16.0.2 16-Channel digital mixer.
For immersive audio research, two Attero Tech unD32 32-Channel Dante break out boxes drive 57 JBL LSR305/LSR308 powered loudspeakers. For studying principles related to the audio chain, several signal processing units from Warm Audio are installed. The collection consists of two WA-12 microphone preamps, two WA-76 1176 style compressor amplifiers and two EPQ-WA, pultec-style tube equalizers.
There are future plans to connect the ASPIRE lab to the school’s CUBE theatre through a high-bandwidth connection to distribute immersive audio for both performance and engineering studies purposes.
