hello friends, this is about PERCEPTUAL WEIGHTING in g729. i know that perceptual weigting is used for manipulate the noise floor with respect to the signal. can anyobody tell me how exactly it will manipulate the noise level. kindly solve my problem you

Dear Members of the List: I have a question regarding the "perceptual weighting filter" used in the AMR-WB (also in the AMR-WB+) codec that is standardized in 3GPP and ITU. Please check the 2002 Journal article from the developers of AMR-WB, where they present the perceptual filter (pages 8-10, and Figures 3 and 4). http://www.gel.usherbrooke.ca/audio/docs/IEEE2002_Bessette.pdf#search=%22pe...

Hi all, I am working on G.729 and when going thru' the C code I came across the folowing: In perceptual weighting filter to find the value of gamma2(weighting parameter) the formula used is gamma2=1-6.0*pi*dmin whereas in the G.729 code it is given as gamma2=1-6.0*
