I had a blast with Avery Bruni at the AES San Francisco Studio Crawl. Starting at Embarcadero visiting Outpost Studio SF and One Union Recording Studios, we walked down to the Hyde Street Studios for beers, pizza, and more studio action. I feel so lucky to have all this and a lot more on my doorstep.
This is the coolest thing I have been involved with for quite some time. Which U87 is the best? We did a shootout of two modern U87Ai, vintage U87, Pelosi P87, Dachman D87, a Eric O.‘s home-brew, and a Slate ML-1 modeling mic. Capturing female vocals, male vocals, acoustic guitar, and a variety of percussion instruments, we have a good data corpus for some blind subjective tests. I’ll report back once we’ve taken a listen with fresh ears. Thanks to Karen Stackpole – CTS, CTFL, John Loose, Samuel Goldburg, Eric O., and Audrey Howard for a fun afternoon!
I will be hosting a tour of some of the audio labs at Dolby headquarters at 1275 Market, San Francisco, on Thu 22nd for members of the Bay Area Chapter of the Acoustical Society of America. The guest list is full but we have a waitlist. Looking forward to a fun evening with fellow audio enthusiasts!
I’m pleased to announce that Dolby Laboratories is a proud sponsor of WASPAA 2023! I have been lucky enough to attend every WASPAA since 2007 and hope for many more to come.
Locked down, not going to conferences, not travelling, working on sensitive stuff I can’t talk about.
Like it says. I’m considering putting together a YouTube miniseries on spatial soundfield capture. Until then, this is all I have…
Check out this animation of optimization for a near-uniform distribution of nodes on the surface of a sphere. Nodes are modeled as charged particles constrained to the surface of a sphere that mutually repel one another. Each frame is an iteration of the optimization process that minimizes the total potential energy in the system. Iterations are stopped after convergence or 200 iterations.
This is an implementation of the solution in M. R. P. Thomas, “Fast Computation of Cubature Formulae for the Sphere,” in proc. Hands-Free Speech Comm. and Microphone Arrays (HSCMA), San Francisco, USA, Mar. 2017.
I just returned from visiting the 2017 WASPAA workshop and 143rd AES Convention in New York. Two very different vibes: the former is a small workshop focused deeply on the theory on topics including source localization, source separation, acoustic scene analysis, spatial audio, dereverberation and de-noising. AES is a huge gathering of audio professionals from music producers to mixers to hardware manufacturers to researchers like me. I’m back at the office with renewed enthusiasm for my profession!
I am often asked for implementations of Maximum-Length Sequences (MLS) and Yet Another GCI Algorithm (YAGA). I created a Downloads Page that I will add to in due course.
