At this year’s IEEE International Symposium on the Internet of Sounds (IS2), the conversation around 3D audio for live music took a meaningful step forward. The new paper and demo, Beyond Marketing: A Holistic Analysis of 3D Audio Workflows for Live Music Production, compared multiple spatial workflows including our now free and open Mach1 Spatial System and public Mach1 Spatial SDK. Using Mach1 tools, the team demonstrated flexible, customizable live-streaming pipelines that deliver higher fidelity than previously achievable.
For the second year in a row, these researchers prioritized real sonic performance over product claims, rigorously testing microphone configurations, panning strategies, and playback setups to understand what truly improves live 3D audio. The group: Claudia Rinaldi, Mauro Galbiati, Stefano Giacomelli, Tiziano Salvi, Nicola Gualandris, and Luca Belotti expanded on their prior IS2 work by developing a distributed live audio/video system linking a concert hall and AV control room via VPN. They evaluated three ambient recording techniques (compact array, distributed array, and second-order analog Ambisonics), two panning algorithms, and a homogeneous 14-loudspeaker playback system. A blind questionnaire captured listener impressions to ensure conclusions were grounded in sonic performance rather than marketing narratives. Looking forward to hearing the final results.
