Re: human versus spectral resolution

This is just for the first part of your email, on time-frequency resolution.

A useful reference would be the book Time-Frequency Analysis by Leon Cohen (1995; Prentice Hall PTR). The entirety of Chapter 3 focuses on the Uncertainty Principle. The book is concerned with most issues related to time-frequency distributions, though it does not include anything on wavelets.

Could anyone please direct me to any literature on what are the comparative limits of : 1) Time/frequency resolution for digital signal spectral analysis , as (sort of) governed by Heisenberg's uncertainty principle with relation to the duration, sampling rate, frequency content and bandwidth of the sound. and 2) The limits of the ability of the human ear to distinquish between frequency/pitch and the exact time location of sounds, more or less the same task as above. Essentially,can a human ear outperform digital ( or even theoretical analysis ) of sounds. Especially, in areas such as pitch discrimination and temporal localisiation of events and not signal separation or some higher level analysis of the sound. Any suggestions will be greatly appreciated. Thanks in advance.
