Abstract

Indications are provided to apply frequency filters to remove unwanted sounds according to frequency. This covers filters with predefined frequency transfer functions, as the preemphasis and Butterworth filters, and filters which cutoff frequencies can be defined by the user, that is, filters based on the short-time Fourier transform and finite impulse response (FIR) filters.
