Dermot, 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.

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.
