— AES Best Papers Awards highlight top research and advancements in the field of audio engineering —

The winners of the Best Peer-Reviewed Paper and Best Student Paper presented during the recent AES New York 2019 Convention were announced in the Convention’s Opening Ceremonies on October 16 by Journal of the Audio Engineering Society Editor Bozena Kostek and 147^th AES International Pro Audio Convention Papers Co-chairs Areti Andreopoulou and Braxton Boren. The awards highlight outstanding contributions from among the submissions of 100 authors from around the world covering the latest research on topics including Loudspeakers, Audio Quality, Applications, Spatial Audio, Processing, Perception, Audio Education and more.

This year’s Best Peer-Reviewed Paper Award goes to Ulrike Sloma, Florian Klein, Stephan Werner, and Tyson Pappachan Kannookadan for their paper “Synthesis of Binaural Room Impulse Responses for Different Listening Positions Considering the Source Directivity.”

Abstract:
A popular goal in research on virtual and augmented acoustic realities is the implementation of realistic room acoustics and sound source characteristics. Additionally, listeners want to move around, explore the virtual or augmented environments. One way to realize position-dynamic synthesis is the use of binaural technologies on the basis of real measurements. While this approach allows the successful reproduction of the real acoustic environment, many listening positions need to be measured. To reduce time and effort, new methods have been invented to calculate binaural room impulse responses from few positions. The presented work enhances existing synthesis methods by including predefined sound source directivities into calculation of binaural room impulse responses. The results are analyzed in a physical and in a perceptive way.

The Best Student Paper Award goes to Robert Hupke and co-authors Lukas Beyer, Marcel Nophut, Stephan Preihs and Jürgen Peissig for their paper “Effect of a Global Metronome on Ensemble Accuracy in Networked Music Performance.”

Abstract:
Several rhythmic experiments with pairs drawn from a group of 23 subjects were performed to investigate the effect of a global metronome on the ensemble accuracy in Networked Music Performance (NMP). Artificial delays up to 91ms were inserted into the audio transmission between the subjects. To investigate the dependencies between delay times, ensemble accuracy and the highly synchronized global metronome, the experiments were evaluated in terms of tempo acceleration, imprecision and subjective judgment of the ensemble play. The results show that the global metronome leads to a stabilization of the tempo acceleration caused by the delay. The imprecision stays constant to a threshold of about 28ms and 36ms, depending on the delay compensating strategy the subjects used.
