StructureTransformer
(name='structure', sr=22050, hop_length=512)[source]¶ Structure agreement transformer.
This transformer maps a labeled, flat structural segmentation to an n*n boolean matrix indicating whether two frames belong to a similarly labeled segment or not.
Attributes: - name : str
The name of this transformer
- sr : number > 0
The audio sampling rate
- hop_length : int > 0
The number of samples between each annotation frame
