16.6.16: You are Surrounded! - Surround Sound Past, Present and Future, University of York
Surround sound is a way to create immersive audio experiences through placing multiple loudspeakers around an audience, in the cinema, theatre or at home. The development of surround sound as we know it has had a rich and varied history but has largely focused on increasing the number of loudspeakers around the audience for a more immersive experience. But can this strategy realistically be employed in the home? Gavin Kearney of the University of York demonstrated how surround sound experiences have evolved from 16th Century Venetian choral performances to the large scale cinematic installations we hear today. The lecture took place at the Department of Theatre, Film and Television at the University of York as part of the York Festival of Ideas.
16.4.16: VR Capture of World Voice Day, York
The Department of Music and Dr Helena Daffern of York Audio Lab hosted a unique event for World Voice Day, showcasing ongoing collaborative research between the Universities of Leeds, Sheffield and York. Over 150 people turned out for 'Mastering Ensemble Singing – the Science and the Art' in the Sir Jack Lyons Concert Hall' on 16 April 2016. Expert vocal coaches Robert Hollingworth (Reader in Music at York and director of the acclaimed vocal ensemble I Fagiolin) and Rob Barber (internationally acclaimed specialist in barbershop performance) coached two quartets of singers: a classical ensemble of York University students and the local Barbershop Quartet, Delekaté. Researchers on the SADIE project took the opportunity to capture the performances for Virtual Reality for use in their project research. Dr. Gavin Kearney led the AudioLab researchers in capturing the performances in First and Higher Order Ambisonics, binaurally using a Neumann KU100 as well as the direct microphones on the performers. Visuals were captured using a Go-Pro OMNI rig. At the same time, the research team of the White Rose College of Arts and Humanities project 'Expressive Nonverbal Communication in Ensemble Performance' set up a range of audio and motion capture recording methods, measuring changes in the performers' individual and group sounds, their expressive body movements and their perceptions of their ensemble development through the session. The audience also provided valuable data on their own perceptions of the developing performances, using 'clickers'. The aim was to provide the public with insights into how researchers are developing both artistic and scientific understandings of how expert ensemble singing develops.
