[Sursound] Nowt new under t'sun
Folks, There is truly nothing new under the sun. (translation by Goggles). I just came across the following patent http://www.google.com/patents/US2173219 for what is essentially a native B Format microphone using ribbon microphones. The filing date? May 29th, 1937! (Actually, I was trying to pinpoint the date when figure of eight microphones were first available - anyone know?)

Re: [Sursound] Nowt new under t'sun
And this http://www.google.com/patents/US1892646 from May 29 (again!) 1931 would be (minus the thermocouples, etc) a full 3D native B format mic!

I think I've answered my own question - here's Harry F. Olson's patent for the ribbon mic http://www.google.com/patents/US1885001 from March 31st 1931. Boy, were those guys on a roll in 1931!

Was there also a patent for a ribbon mic in the UK, perhaps even earlier? (Blumlein?) David At 05:29 21/12/2011, dave.mal...@york.ac.uk wrote: I think I've answered my own question - here's Harry F.

I remember reading that early (1930's?, German?) radio mixing desks had a 360 degree panpot for M/S stereo, or Blumlein pairs. But I don't remember where I read that. Can anyone confirm? Maybe it's just wishful thinking. best wishes, Justin.

-to-noise ratios reastic, which is a weakness of many studies. To date, studies have not shown significant improvement with binaural CIs over a single CI when speech stimuli are presented in noise. It is my belief that spreading the noise about (i.e. periphony) will make the tests more valid, regardless of outcome. Many thanks to anybody who can provide insight or links to articles regarding any of the questions (by the way, as an AES member, I can download articles from the AES library--I just need title/author in order to access articles).

[Sursound] Fwd: Santa LACus (your Xmas Linux Audio Conference 2012 reminder)
Hi all, Just a friendly reminder that JANUARY 11 is the deadline for all submissions to the Linux Audio Conference (LAC 2012), which will take place at CCRMA (Stanford, California) in April 2012!http://lac.linuxaudio.org/2012/ Santa LACus wishes a great paper-and-music-submitting holiday to all! Ho, ho. Bruno - - - - - - - - - LAC 2012: the Linux Audio Conference - Call for Participation April 12-15, 2012 @ CCRMA, Stanford University http://lac.linuxaudio.org/2012/ [Apologies for cross-postings] [Please distribute] Online submission of papers, music, installations and workshops is now open! On the website you will find up-to-date instructions, as well as important information about deadlines, travel, lodging, and so on. Read on for more details! We invite submissions of papers addressing all areas of audio processing based on Linux and open source software. Papers can focus on technical, artistic or scientific issues and can target developers or users. We are also looking for music that has been produced or composed entirely or mostly using Linux and other Open Source music software. The Deadline for all submissions is January 11th, 2012 The Linux Audio Conference (LAC) is an international conference that brings together musicians, sound artists, software developers and researchers, working with Linux as an open, stable, professional platform for audio and media research and music production. LAC includes paper sessions, workshops, and a diverse program of electronic music. The upcoming 2012 conference will be hosted at CCRMA, Stanford University, on April 12-15. The Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University is a multi-disciplinary facility where composers and researchers work together using computer-based technology both as an artistic medium and as a research tool. CCRMA has been using and developing Linux as an audio platform since 1997. http://ccrma.stanford.edu Stanford University is located in the heart of Silicon Valley, about one hour south of San Francisco, California. This is the first time LAC will take place in the United States. http://www.stanford.edu We look forward to seeing you at Stanford in April!
