VASI Posted January 16, 2013 Report Share Posted January 16, 2013 Audio Engineering Society : Announcement AES64-2012 Command, control, and connection management for integrated media This standard for networked command, control, and connection management for integrated media is an IP-based peer-to-peer network protocol, in which any device on the network may initiate or accept control, monitoring, and connection management commands. The AES64 protocol has been developed around three important concepts: structuring, joining, and indexing. Every parameter is part of a structure, and control is possible at any of the levels of the structure, allowing for control over sets of parameters. Parameters can be joined into groups, thereby enabling control over many disparate parameters from a single control source. Every parameter has an index associated with it and, once discovered, this index provides a low bandwidth alternative to parameter control.

VASI Posted January 28, 2013 Author Report Share Posted January 28, 2013 Audio Engineering Society: Announcement AES55-2012 MPEG Surround in an AES3 bitstream MPEG-D is an ISO/IEC standard describing MPEG Surround that extends mono or stereo audio towards multiple channels. The mono or stereo audio channels represent a downmix of the original multi-channel audio that is generated by the MPEG Surround encoder. In addition the MPEG Surround encoder generates spatial side information (MPEG Surround data). An MPEG Surround decoder is able to combine this information with the downmix to result in a multi-channel audio signal. In this way backward compatibility to mono and stereo systems is achieved. More recently, MPEG-D has been revised to include MPEG SAOC (Spatial Audio Object Coding) that uses the same method to convey the related side information over PCM. This standard specifies how MPEG Surround or MPEG SAOC shall be carried within an AES3 bitstream where the downmix channels remain in the linear PCM domain and the MPEG Surround or MPEG SAOC data is embedded into the least-significant bits of the PCM audio data.

VASI Posted January 30, 2013 Author Report Share Posted January 30, 2013 Audio Engineering Society: Announcement AES31-2-2012 Audio file format for interchange The Broadcast Wave Format is a file format for audio data. It can be used for the seamless exchange of audio material between (i) different broadcast environments and (ii) equipment based on different computer platforms. As well as the audio data, a BWF file (BWFF) contains the minimum information - or metadata - that is considered necessary for all broadcast applications. The Broadcast Wave Format is based on the Microsoft WAVE audio file format. This specification adds a “Broadcast Audio Extension” chunk to the basic WAVE format. This revision of AES31-2-2006 incorporates the content of Amendment 1 (2008) that specifies an optional Extended Broadcast Wave Format (BWF-E) file format, designed to be a compatible extension of the Broadcast Wave Format (BWF) for audio file sizes larger than a conventional Wave file. It extends the maximum size capabilities of the RIFF/WAVE format by increasing its address space to 64 bits where necessary. BWF-E is also designed to be mutually compatible with the EBU T3306 "RF64" extended format. This revision additionally packages a set of machine-readable loudness metadata into the BWF file. This is compatible with EBU v2 broadcast wave files. Thursday, January 24, 2013 More informations: http://bit.ly/XjvTQQ Quote Link to comment Share on other sites More sharing options...
VASI Posted February 22, 2013 Author Report Share Posted February 22, 2013 Audio Engineering Society: Announcement AES65-2012 Connector for surround microphones An increasing number of surround sound microphones are becoming available, however, there has been no common standard for the connectors between microphone and recording device. It is expected that a standard connection will create a basis for smaller and lighter recording devices. This standard specifies a connector type and contact assignment for microphones having up to six balanced analog output channels, as used in surround sound applications. It includes specifications for marking and identification for the audio channels. It includes recommendations for cable type and detailed wiring. It is expected that other applications will also use this connection.

VASI Posted March 7, 2013 Author Report Share Posted March 7, 2013 Audio Engineering Society: Announcement AES66-2012 Miniature XLR-type polarity and gender This standard is intended to apply to three- and five-pin circular connectors, commonly and generically known as miniature XLR-type, used for the balanced interconnection of all categories of sound system components for professional audio, commercial, recording, broadcast, and similar applications, regardless of function, type, or level of the signal. It specifies the application and polarity of analog signals for these connectors and is intended to avoid the inversion of absolute polarity among the items in the analog signal chain.

Eric Toline Posted March 7, 2013 Report Share Posted March 7, 2013 New users of the 3 pin mini XLR / TA3 connector should be aware that the connection points are different than the normal size XLR's. On the normal size XLR the pin connections are: 1 2 3 The TA 3 is 1 3 2 Eric Quote Link to comment Share on other sites More sharing options...
VASI Posted August 8, 2013 Author Report Share Posted August 8, 2013 51st International AES Conference to Focus on Loudspeakers and Headphones New York, NY, August 6, 2013 — Following the highly successful 50th International Conference in Murfreesboro, Tennessee, which focused on audio education, the Audio Engineering Society (AES) will hold its 51st International Conference in Helsinki, Finland, August 21-24, 2013. The conference will feature a first-ever program dedicated to Loudspeakers and Headphones and the technologies associated with their design and performance. This event will bring together top names in the industry for four days of in-depth programs, sessions and tutorials, kicking-off with the keynote address given by Genelec Founder and Chairman Ilpo Martikainen on the evolution and history of the loudspeaker as we know it today. Driven by today’s changing landscape of portable audio devices, advances in digital signal processing and improved measurement technology, both miniature transducers, as well as full range systems, are seeing the benefits of the latest research and advances in speaker design and manufacturing technology. This AES Conference, chaired by Juha Backman (Nokia Corporation), will feature presentations by key industry professionals including Sennheiser’s Axel Grell speaking on the topic “Headphones – From Alexander Graham Bell to a Mass Phenomenon,” and Linkwitz Lab’s Siegfried Linkwitz addressing his mission of “Finding the Prototype for Stereo Loudspeakers.” Additional tutorials on a wide range of related topics will be presented by Wolfgang Klippel (Klippel GmbH), Peter Larsen (LOUDSOFT), John Richards (Oxford Digital), Simon Woollard (Prism Sound), Lars Risbo (Texas Instruments), and Anthony Waldron (Audio EMC). These will cover topics ranging from loudspeaker data, design and optimization, to loudspeaker analysis and powered amplification. http://www.aes.org/press/?ID=212 Quote Link to comment Share on other sites More sharing options...
