# pymultitaper

`pymultitaper` is a fast and easy-to-use small package for multitaper spectrogram/spectrum calculation, as well as oridnary (single-taper) spectrogram calculation.

# Installation

Install via pip:

```

pip install pymultitaper

```

# Usage

```python

>>> from pymultitaper import multitaper_spectrogram, plot_spectrogram

>>> from scipy.io import wavfile

>>> fs, data = wavfile.read('test.wav')

>>> freqs,times,psd = multitaper_spectrogram(

...     data, fs,time_step=0.001,window_length=0.005,NW=4

... )

>>> fig,ax = plot_spectrogram(times,freqs,psd,cmap="viridis")

```
