Bespoke loudspeaker array for spatial audio research
- 50-channel Ambisonic loudspeaker system in a Lebadev grid configuration
- Augmented with 2 additional speakers to produce an embedded 7.1.4 playback system
- Laser system for precise subject alignment
- Vicon motion tracking system allowing for full body tracking
- Acoustically treated to provide short reverberation time (<100ms)
- Software provision includes tools for ambisonic/object-based mixing
Genelec System
Fitted with 52 Genelec 8331 loudspeakers
Constructed using a bespoke mounting system in a 50-point Lebadev grid configuration.
Custom Decoding
In-house developed decoders
Decoding and equalisation has been designed and implemented specifically for this system by members of our lab.
Realtime Rendering
Custom-built PC
The computational power required to render 7OA in realtime, allowing for the composition of immersive spatial mixes.
Embedded Screens
HD monitors
Mix audiovisual media from the sweet spot of the loudspeaker array.
Binaural Decoding
Load in in custom HRTF sets
Decoding to headphones facilitates the testing of different HRTF sets.
Head-Tracking
Vicon Motion Capture System
Enables head-tracked audio to be played back to a listener wearing headphones from within the loudspeaker array.
AB Testing
Loudspeakers vs Binaural
Switch back and forth between the loudspeakers and different HRTF sets for critical evaluation.
HOA Workflows
Reaper and Pro Tools
Established workflows using both Reaper and Pro Tools to produce 7OA materials.
Motion Capture
The rig is fitted with a full motion capture system including 10 Vicon Vero v2.2 Cameras and Shogun Live Software.
