Projects assigned to this group but not mentioned here had no action requested or required - see www.aes.org/standards/meetings/project-status.cfm for details.
AES3-4-R: Review of AES3-4-2009 (r2014), AES standard for digital audio - Digital input-output interfacing - Serial transmission format for two-channel linearly represented digital audio data - Part 4: Physical and electrical
J Paul was unable to find time to produce revised drafts and has now left the Working Group. There is still a need to update this standard and AES-2id, to reflect current practice and to correctly distribute normative and informative text between the two documents; P Treleaven has posted a summary of the previous discussions to the reflector; S Scott offered to contribute but does not have time to lead the work.
AES5-R: Review of AES5-2008 (r2013): AES recommended practice for professional digital audio - Preferred sampling frequencies for applications employing pulse-code modulation
The revised text is out for public comment; there have been no comments so far. R Hess has offered to draft an Information Document covering the issues that have previously been discussed, Secretariat to follow up; B Harris offered to contribute.
AES10-R: Review of AES10-2008: AES Recommended Practice for Digital Audio Engineering - Serial Multichannel Audio Digital Interface (MADI)
The various proposals that have been made over the past few years are not now expected to result in any revision.
AES53-R, Review of AES53-2006 (r2011), AES Standard for digital audio - Digital input-output interfacing - Sample-accurate timing in AES47
There were no issues raised during the public comment period on the revised text; now ready for publication.
No formal liaison was sent to SMPTE regarding the AES5 revision, but K Gross had several informal conversations with SMPTE members.
No new projects were proposed.
