# Utilities for `FeatureExtractors` |
|
|
|
This page lists all the utility functions that can be used by the audio [`FeatureExtractor`] in order to compute special features from a raw audio using common algorithms such as *Short Time Fourier Transform* or *Mel log spectrogram*. |
|
|
|
|
|
Most of those are only useful if you are studying the code of the image processors in the library. |
