How do you read a mel spectrogram?

A mel spectrogram logarithmically renders frequencies above a certain threshold (the corner frequency). For example, in the linearly scaled spectrogram, the vertical space between 1,000 and 2,000Hz is half of the vertical space between 2,000Hz and 4,000Hz.

How do you save a spectrogram in Python?

To save the created spectrogram, first convert it to an image. It will no longer be an OpenSoundscape Spectrogram object, but instead a Python Image Library (PIL) Image object. Save the PIL Image using its save() method, supplying the filename at which you want to save the image.
