Module report 

The outputs of a stem: layers.json, spectrogram.png and the final notes.mid from analyze, and the first notes.mid from notes.

analyze decodes the stem, refines its tempo, reads the note list if one is given or else runs the notes step, reads the pitch layer, runs the stem estimators and the descriptors, maps the pitch, voices and envelope groups to the synth’s suggested edits, rewrites the note list with the layers into the final notes, and writes the three files into the output folder. notes refines the tempo, transcribes the stem and writes its notes into the same folder. The schema of layers.json is committed as schemas/layers.schema.json.

Functions

analyze

Analyses a stem and writes layers.json, spectrogram.png and, when the stem has notes, the final notes.mid into the output folder, creating it.

analyze_with

analyze with a given mapper for the suggested edits, such as a test mapper. Without one, or for a synth without a registry, every suggested_edits and unrepresentable list is empty.

layers_json

Renders the report of a stem as pretty-printed JSON with a final newline. The same stem always gives the same bytes.

notes

Transcribes a stem and writes notes.mid into the output folder, creating it.
