Title: Can Audio be further Compressed by Replacing FFT Magnitude Spectrum with Excitation Pattern
Dear Experts and Lists,
I would be most grateful if you could give any comment, advice and further information about the idea: further audio compression with excitation pattern replacing the FFT magnitude spectrum used in calculating masked threshold and the related bit allocation in current audio codecs such as AC3 and AAC. . The motivation for this thought is on the basis of the fact that excitation patterns are much flatter than the magnitude spectrum.
Thank you for your kind attention.
I am looking forward to hearing your Reponses.
