Network Setup

Phipp’s Hall, University of Huddersfield, and the AudioLab, University of York, were connected over the internet using the existing academic internet access at each endpoint (JANET). JackTrip was used to stream audio between endpoints, and JACK was used to route audio between JackTrip and hardware capture/playback buffers. A full system throughput latency of approximately 16ms was achieved. Local Mic capture and JackTrip receive channels were recorded at each endpoint.

Spatial Audio Production Workflow

Based on the time-aligned stems from the performance, two selected pieces were mixed in 7th-order Ambisonics. The virtual singer postions were uniformly distributed in front of the listener in a perfect half-circle.

Virtual Acoustics

Early reflections and late reverberation were added based on a simulation of BBC Maida Vale Studio 2 room.

The binaural files were rendered using MagLS filters calculated from SADIE II KU100 HRTFs.
