Re: Masking Models PEAQ (Spreading Functions Used)


I recommend that you start out by reading "PEAQ--The ITU Standard for
Objective Measurement of Perceived Audio Quality", which appeared in the
Journal of the Audio Engineering Society, Vol. 48, No. 1/2, 2000
January/February.  Much of the modeling came from Zwicker, but there is
also a great deal of baggage in the PEAQ standard in terms of residue
from the objective measurement techniques that came before it.

If for whatever reason you cannot obtain a copy of this paper, contact
me directly.

Subject: Masking Models PEAQ (Spreading Functions Used)

Hello 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

Thanks in advance to anyone who is able to help me, please feel free to
email me if my email is a little vague.

Kind Regards,
