Re: On the use of windows



"Crockett, Brett" <BGC@xxxxxxxxx> pointed to Louis Fielder at Dolby. The Dolby E
coding system uses a number of windows of varying lengths and shapes and Louis
did extensive work on optimizing the windows for the coding system.

I would like to remind of cochlear spectral analysis. I am claiming that both
cochlea and my cosine transform based spectrogram do not at all require an
arbitrarily chosen window. In other words: To one side the border is given by
elapsed time = 0, but to other side attenuation sets a gradual horizon. Natural
optimizing happend within about one hundred millions of years.

Awkwardness of traditional technology including FFT is manmade.
