AES-12id-R: Review of AES-12id-2006: AES information document for digital audio measurements - Jitter performance specifications

Project scope: This information document reviews various ways of characterizing and quantifying jitter, and refines several of them for audio purposes. It also attempts to present a common, unambiguous terminology. Its focus includes wideband jitter, baseband jitter, jitter spectra, period jitter, long-term jitter and jitter signatures. Comments are made on jitter transfer through phase-locked loops and on the jitter susceptibility of audio converters.
Assigned to: SC-02-01 , Status: New printing issued with editorial correction to figure 10, 2007-05-08, and add editorial pointers to AES3 and AES-2id for interface jitter.
Intent: Review , Initiated: 2006 , Target: 2011
Current goal: new printing , Goal date: 2008-06

AES17-R: Review of AES17-1998 (r2004): AES standard method for digital audio equipment - Measurement of digital audio equipment

Project scope: to provide methods for specifying and verifying the performance of digital audio equipment, and specifically to describe the testing of medium- and high-performance digital audio equipment.
Assigned to: SC-02-01 , Status: Revision ongoing to include (eg) multitone testing. Next draft by mid 2008
Intent: Revision , Initiated: 2004 , Target: 2009
