In this episode of the Immersive Audio Podcast, Oliver Kadel is joined by the academic and researcher at Imperial College – Lorenzo Picinali from London, United Kingdom.

Lorenzo Picinali is a Reader at Imperial College London, leading the Audio Experience Design team. His research focuses on spatial acoustics and immersive audio, looking at perceptual and computational matters, as well as real-life applications. In the past years Lorenzo worked on projects related to spatial hearing and rendering, hearing aids technologies, and acoustic virtual and augmented reality. He has also been active in the field of eco-acoustic monitoring, designing autonomous recorders and using audio to better understand humans’ impact on remote ecosystems.

Lorenzo talks about the breadth of research initiatives in spatial audio under his leadership of the Audio Experience Design group and we discuss the recently published SONICOM HRTF Dataset developed to improve personalised listening experience.

Episode 73 Arjen Van Der Schoot (Audio Ease)

Summary

This episode is sponsored by Spatial, the immersive audio software that gives a new dimension to sound. Spatial gives creators the tools to create interactive soundscapes using our powerful 3D authoring tool, Spatial Studio. Their software modernises traditional channel-based audio; by rethinking how we hear and feel immersive experiences, anywhere. To find more go to https://www.spatialinc.com.

In this episode of the Immersive Audio Podcast, Oliver Kadel and Monica Bolles are joined by the co-founder at Audio Ease – Arjen Van Der Schoot from Utrecht, Netherlands.

Arjen studied music technology at the Utrecht School of Arts. After which Arjen and 4 of his fellow graduates started Audio Ease in 1995. He was freelancing recording Classical music, Minoring in Classical guitar and majoring in software development for audio and music. Together they made about 10 products before their big break with Altiverb which became an industry standard. The 360pan suite came out of the fierce hope that an old affection – ambisonics, would now finally definitely make it, because somebody thought of it in the context of head-tracked VR, an application that requires headphones, in Arjen’s opinion the only medium it is perfect for.

Arjen tells a fascinating story of the creation of Audio Ease and the famous Altiverb and we explore the topic of convolution for spatial audio.

Episode 62 Nikunj Raghuvanshi & Noel Cross (Microsoft – Physics Based Virtual Acoustics)

Summary

In this episode of the Immersive Audio Podcast, Oliver Kadel, Monica Bolles and Bjørn Jacobsen are joined by a Principal Dev Leader at the Mixed Reality division at Microsft Noel Cross and Senior Principal Researcher at Microsoft Research Nikunj Raghuvanshi from Redmond, US.

Nikunj likes to invent techniques that create immersive sight and sound from computation. He is endlessly fascinated with simulating the laws of physics in real-time and finds it thrilling to search for simple algorithms that unfold into complex physical behaviour. He has over a decade of research and development experience at the intersection of computational audio, graphics, and physics, with over fifty papers and patents. His inventions have been successfully deployed in the industry, particularly Project Acoustics, which is bringing immersive sound propagation to many major AAA game franchises today. Nikunj is currently a Senior Principal Researcher at Microsoft Research. Previously, he initiated interactive sound simulation research at UNC-Chapel Hill during his PhD studies, whose codebase was acquired by Microsoft. 

Noel grew up playing games on my Commodore 64 and Amiga computers. His love for multimedia computing helped him to start working at Microsoft as an intern in 1991 in the multimedia team. This was the age of the SoundBlaster 16 ISA cards and CD-ROMs were just being introduced into PCs.  Out of the multimedia team, the DirectX team was born to accelerate the development of high-quality games for the PC. Noel worked on DirectSound and audio drivers for Windows getting a taste of the game development community attending several GDCs in the 90s. This was the first time he was introduced to 3D audio algorithms and at the time the technology didn’t impress much.  Through the 2000s, he worked on every release of Windows with the focus on improving the audio subsystem. This led to the complete overhaul of the audio infrastructure on the Windows Vista platform which has remained largely intact since introduced in 2006.  The most current stop on his Microsoft journey is working on Mixed Reality devices. He worked on the speech and audio functionality exposed from HoloLens and Windows Mixed Reality devices with a concentration on spatial audio. After having lackluster impact in the 90s with spatial audio, he’s been reinvigorated working on this technology with the introduction of high-quality HRTFs and head-tracking services to complete the experience. Spatial audio processing has also led Noel to better understand the impact of acoustics on virtual 3d worlds. His team is currently working on Project Acoustics which allows developers of 3d titles to take advantage of wave-based simulations to handle how audio propagates in the real world.

In this episode, Nikunj and Noel dive deep into the topic of physics-based virtual acoustics along with Project Triton and Project Acoustics covering fundamental theory, research, technology and case studies.
