Envelope reconstruction of speech and music highlights stronger tracking of speech at low frequencies
Fig 1
(A) 20 seconds of example dB envelopes for each stimulus type. (B) Power spectra of the dB envelopes using Welch’s method with a 16 s Hamming window and half-overlap after normalizing by the average EEG spectrum for all subjects (see Methods). Lines indicate the median across stimuli of each type, and shaded regions indicate 95% quantiles of the distribution of 1000 bootstrapped median values.
