Feature Extractor
-----------------------------------------------------------------------------------------------------------------------

A feature extractor is in charge of preparing read-in audio files for a speech model. This includes feature extraction,
such as processing audio files to, *e.g.*, Log-Mel Spectrogram features, but also padding, normalization, and
conversion to Numpy, PyTorch, and TensorFlow tensors.
