pymultitaper is a fast and easy-to-use small package for multitaper spectrogram/spectrum calculation, as well as oridnary (single-taper) spectrogram calculation.
Install via pip:
pip install pymultitaper
>>> from pymultitaper import multitaper_spectrogram, plot_spectrogram
>>> from scipy.io import wavfile
>>> fs, data = wavfile.read('test.wav')
>>> times,freqs,psd = multitaper_spectrogram(
... data, fs,time_step=0.001,window_length=0.005,NW=4
... )
>>> fig,ax = plot_spectrogram(times,freqs,psd,cmap="viridis")Refer to pymultitaper documentation for more details.
