MultitaperTfr applies the multitaper PSD estimator (MultitaperPsd) to consecutive overlapping windows of a signal, producing a time-frequency matrix whose columns share the bias–variance properties of Thomson's classical multitaper spectrum. Compared with the complex-Morlet TFR (MorletTfr) the frequency resolution is fixed to the time-half-bandwidth product NW of the window rather than scaling with frequency, which makes the multitaper TFR the preferred choice when broadband line-noise leakage or non-stationary high- frequency activity (e.g. high-gamma) has to be resolved without over-smoothing in time.

The number and concentration of tapers, window length, step size and frequency grid are all user-controlled; defaults mirror those of mne.time_frequency.tfr_array_multitaper.
