Immersive Audio - How much quality is necessary?
Date:
Fri, 02/10/2023 - 10:30am - 12:00pm
Location:
CCRMA Ballroom
Event Type:
Hearing Seminar I'm every pleased that we'll be joined by three experts on immersive sound, from three different directions (no pun intended):
- JJ Johnston is chief scientist at Immersion Networks, where he is thinkling about how to create immersive audio envirnments, and how should we judge quality.
- Scot Stafford, CEO of the Pollen Music Group, who are experts on creating immersive audio environments.
- Fernando Lopez-Lezcano, Veteran Stanford 3D Audio composer
What: Immersive Audio Quality - How much is enough?
When: Friday February 10, 2023 at 10:30AM
Where: CCRMA Ballroom (middle floor of the Knoll)
We hope you’ll be at CCRMA for the full immersive audio experience, but if you can’t make it, here is a broadcast only Zoom link. Details follow the biographies attached below.
The director's comments for the movie "The Sound of Music" start with interviewer asking the director if he read the book. He answered, paraphrasing, "h*ll no. I just want to tell a good story." Do we, or should we, care more about accuracy or emotional responses, or something else? Is the answer different for games vs. music? What do you want from an immersive experience???
Come to CCRMA to talk about the next stage of immersive audio. We’ll fully immerse you in the discussion.
Dr. Johnston was the primary researcher and inventor of the MPEG-2 AAC audio coding algorithm, and a principle contributor to the "MP3" algorithm. He also represented AT&T in the ANSI accredited group X3L3.1, and X3L3.1 in the ISO-MPEG-AUDIO (MP3, AAC) arena. Dr. Johnston was awarded the IEEE James L. Flanagan Signal Processing Field Award (2006); elected Fellow, Audio Engineering Society (1997); received AT&T Technology Medal and AT&T Standards Award (1998); received a New Jersey Inventor of the Year Award (2001); elected IEEE Fellow (2002). Dr. Johnston (JJ) retired from DTS Inc. Prior to that he worked at Neural Audio. Before that, he worked for 5 years at Microsoft Corporation in the "Codecs", "Core Media Processing" and finally the video services groups as Audio Architect. Dr. Johnston retired from AT&T Labs - Research, quartered at Florham Park, NJ, Speech Processing Software and Technology Research Department. Before that, he was employed by AT&T Bell Laboratories, in the Acoustics Research Department under Dr. J. L. Flanagan, and in the Signal Processing Research Department.
Dr. Johnston’s current research interests include acoustic scene modelling, loudspeaker design, loudspeaker pattern control, cochlear modelling, masking threshold models, stereo imaging models and stereo imaging sensitivity models, methods of reproducing soundfields either literally or perceptually, microphone and soundfield capture techniques, both actively steered and time-invariant, and speech and audio coding methods in general.
James D. Johnston (Fellow of the IEEE and AES) received his BSEE and MSEE from Carnegie-Mellon University.
Scot Stafford is a sound supervisor and composer in film, animation, and immersive formats. He helped lead Google Spotlight Stories as Creative Director of Music & Sound from its founding in 2012 until it closed its doors in 2019. The Emmy-nominated VR experience SONARIA was his directorial debut. His other XR projects have garnered four MPSE awards for sound, a Peabody, and an Emmy. He co-founded his music and sound design company Pollen Music Group (San Francisco) in 2010, and Pollen Audio Group (Emeryville, CA) in 2019. PAG serves as Pollen's R&D wing dedicated to prototyping and user testing sound-driven technology and immersive experiences.
Fernando Lopez-Lezcano was given a choice of instruments when he was a kid and liked the piano best. His dad was an engineer and philosopher, his mother loved biology, music and the arts. He studied both music and engineering, and tries to keep them balanced. He has been working at CCRMA since 1993. He throws computers, software algorithms, engineering and sound into a blender and serves the result with ice in tall glasses, and over many speakers. He can hack Linux for a living, and sometimes he likes to pretend he can still play the piano. He built El Dinosaurio (an analog modular synth) from scratch 40 years ago, and it still sings its modular songs. He also loves to distill music from pure software. His modular herd, which he is still trying to tame, grew recently, and includes El Dinosaurio, a Noise Toaster, a Kastle, an ARP 2600 clone and the big Applesauce Mark V eurorack (and a fake piano!). He was the Edgard-Varèse Guest Professor at TU Berlin in 2008.
