Masking Models PEAQ (Spreading Functions Used)

[Dermot Campbell <dermot.campbell@xxxxxxxxxxxx>]

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 
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.

Kind Regards,
