Re: Masking Models PEAQ (Spreading Functions Used)
Thanks for the many replies. There were 1 or 2 papers in particular that
I was missing that should clear up a few things. A number of you emailed
me to ask me to pass on personal replies so here is a summary of the
important information. Thanks to everyone who took the time to respond
to help me out here:
(1) PEAQ--The ITU Standard for Objective Measurement of Perceived Audio
(2) Zwicker's Work
(3) T. Thiede, W. C. Treurniet, R. Bitto, C. Schmidmer, T. Sporer, J. G.
Beerends, C. Colomes, M. Keyhl, G. Stoll, K. Brandenburg, B. Feiten,
"PEAQ - The ITU-Standard for Objective Measurement of Perceived Audio
Quality," J. Audio Eng. Soc., vol. 48, pp. 3-29 (2000 Jan/Feb).
(4) J. G. Beerends and J. A. Stemerdink, "A Perceptual Audio Quality Measure
Based on a Psychoacoustic Sound Representation," J. Audio Eng. Soc.,
vol. 40, pp. 963-978 (1992 Dec.)
(5) ITU-R BS.1387-1
(6) An Examination and Interpretation of ITU-R BS.1387, P. Kabal
(7) Perceptual Audio Quality Assessment using a Non-Linear Filter Bank,
T. Thiede (Google it) - Including DIX
Many thanks again to all.

I have a query about the PEAQ algorithm (BS.1387 ITU standard) that
someone may be able to help me with on here.
I’m trying to trace the origins of the masking models (spreading
functions that is), both frequency and time domain spreading, used in
PEAQ. Where did these masking models originate and was different
time/frequency spreading techniques tested? I’m finding it difficult
to trace papers where these spreading functions have been developed,
tested etc. Also, is it possible to obtain details on work carried out
by the ITU in the lead up to the official standardisation of PEAQ
(study groups etc)?
Thanks in advance to anyone who is able to help me, please feel free
to email me if my email is a little vague.
