python - Resample a numpy array - Stack Overflow
https://stackoverflow.com/questions/29085268/resample-a-numpy-array
Since you mention this being data from an audio .WAV file, you might look at scipy.signal.resample.. Resample x to num samples using Fourier method along the given axis.. The resampled signal starts at the same value as x but is sampled with a spacing of len(x) / num * (spacing of x).Because a Fourier method is used, the signal is assumed to be periodic.

NumPy
NumPy is an essential component in the burgeoning Python visualization landscape, which includes Matplotlib, Seaborn, Plotly, Altair, Bokeh, Holoviz, Vispy, Napari, and PyVista, to name a few. NumPy’s accelerated processing of large arrays allows researchers to visualize datasets far larger than native Python could handle.
