Report from the 127th AES Convention in New York, October 10, 2009 =========================================================================== Attendees ========= Steven Harris (BridgeCo) Umberto Zanghieri (ZP Engineering) Kevin Gross (AVA Networks) Robby Gurdan (UMAN) Richard Foss (Rhodes Universal Media Access Networks) Nathan Brock (UCSD) Thomas Sporer (Fraunhofer IDMT) Jeremy Cooperstock (McGill U.) Rick Kreifeldt (Harman) Bradford Benn (Harman) Elizabeth Cohen (UCLA) Al Walker (KlarkTeknik) Jérémie Weber (Auvitran) Bob Economaki (Cisco) Richard Foss (UMAN) Peter Alyea (Library of Congress) Mark Gilbert (Shure) Nathan Brock (UC San Diego) Larry Bryan (Tennessee Performing Arts Center) Tim Shuttleworth (Renkus-Heinz) Kevin Heber (Harman) Zeb Wall (Harman) It was asked if there were any objections to adding new attendees' emails to the TC-NAS mailing list; none objected. =========================================================================== 1. It has been mentioned that the convention calendar offered several entries related to audio networking: * Paper Session P17 "Audio Networks" * Broadcast Sessions B4 "Digital Audio Networks in the Studio" and B5 "IP Audio - out of the studio: connecting anywhere" * Workshop W11 "Redundancy in Audio Networks" * Live Sound Seminar L10 "Networking Digital Audio in Live Sound" 2. Emerging trends report The documents needs an update. Kevin will post to TC-NAS reflector the following: - current emerging trends report - AVB update for emerging trends report Others are encouraged to post emerging trend topics to the reflector and provide corrections or updates to posted materials. Thomas Sporer will continue to serve as editor for the report 3. Whitepaper corrections Some minor edits are needed: - correct some LiveWire entries on matrix comparison. - add Steve Harris to list of authors - add Elizabeth Cohen to list of authors The amended document will be put on the TC-NAS web page for future reference. Corrections will also be communicated to William Wade for potential JAES correction notice. 4. Event suggestions - Elizabeth Cohen suggested “Sustainable digital preservation” workshop in conjunction with TC-ARDL. - Umberto Zanghieri suggested repeating “Redundancy in digital audio networks” in London - Robert Economaki, Kevin Gross and Bradford Benn suggested a tutorial on networking for San Francisco. Kevin will submit an application at AES.org on this. - Jeremy Cooperstock, Robby Gurdan and Elizabeth Cohen suggested a paper or tutorial on “Long distance audio”. - Richard Foss suggested a workshop on sound control. Richard will submit an application at AES.org on this. 5. Standards suggestions Control protocols and discovery were discussed. These are currently being discussed in IEEE 1722.1. TC-NAS members are welcome to join the work in progress there. AES involvement is not seen as being beneficial to the effort. The URL for the IEEE 1722 effort is - http://grouper.ieee.org/groups/1722/. The 1722.1 group is in the process of organizing itself. The chair is Matt Mora from Apple. Kevin Gross suggested a potential standards initiative for creating interoperability of uncompressed audio over IP. Interoperability exists for compressed formats in broadcast applications but at least three formats exist for sound-reinforcement applications. 6. Other business Nathan Brock briefed TC-NAS on plans for a 3-1/2 day Networked audio conference in San Diego in November 2011. Richard Foss suggested starting a journal on networked audio. Richard will contact William Wade to see if the Journal would consider publishing a special topics issue on networked audio.
