Hi everybody! There is one thing I've been thinking about regarding the psychoacoustic models used in MPEG Audio. Do the models know about the equal-loudness curves or do they assume that your ears have a flat frequency response? I have studied both models described in the standard document (ISO/IEC 11172-3) and it seems to me that the models assume (apart from the ATH) that the frequency response of the ears is flat. Am I correct? If so, could putting a stuitable filter just before the psychoacoustic models improve the sound quality? Thanks for any responses to my thoughts!
