Audio feature pack -- week 2
Authored teaching scenario. The features below are constructed to show how a shared property is reasoned about. Nothing here was measured from a real tape, a real deck or a real recording.

One source recording and four copies of it. You are not given the recordings:
the evidence is the feature table, and the inference runs on the table. Supplying
clips would let hearing affect the answer, and this task is not about hearing.

feature-table.csv is the evidence -- six features, and whether each appears in the
source and in each copy. features.txt lists what the features are and where they
sit. s.txt, w.txt, x.txt, y.txt and z.txt say the same thing per recording.

Nothing in these files says which features matter or where any copy came from.
Working that out is the task.

reveal/ holds the construction log. Open it after you have an answer.
