Spectral analysis cannot achieve fine time and frequency resolution simultaneously
Evidence
It is not possible to have a very fine time and frequency simultaneously: this status is incompatible. … The record length and the filter bandwidth of a STFT are inversely proportional and are not independent. — Almo Farina, Soundscape Ecology, 1970
