Eardrums writing scores: time-frequency analysis, the handbook of absolute pitches
nell'ambito della serie: SEMINARI BAD
analisi matematica
A score contains all the information needed to reproduce a music signal in time: the octaves representing different frequency intervals. Time-frequency analysis is a branch of harmonic analysis that studies the relations between tempered distributions and their Fourier transforms that, in this context, precisely represent the amplitude of a signal in time and the amplitude of its frequencies. This seminar aims to provide a brief introduction on several aspects of time-frequency analysis: from uncertainty principles, mathematical results providing hindrances to the exact localization of signals, to pseudodifferential operators, whose study fits surprisingly and naturally into a time-frequency analysis setting.
