"""Batch side-by-side inspector/editor for audio + two/three RTTM annotations.
Scans an experiment directory whose sub-directories each contain items of
the form <id>.wav + <id>.rttm + <id>_3D.rttm [+ <id>_GT.rttm], and serves
a compare/edit page with prev/next navigation across all items. Panels:
GT = <id>_GT.rttm (parquet annotation, optional), A = <id>.rttm (DiariZen),
B = <id>_3D.rttm (3D-Speaker).
Speakers of every panel are auto-matched (by maximal overlap) against the
anchor annotation (GT when present, else A) so matched speakers share a
color, and a "diff" strip highlights every region where a selectable pair
of annotations disagree (speech only in one, or attributed to different
speakers). All annotations are editable (move/resize/reassign/split/
delete/create, undo/redo); each RTTM saves to "<original-stem>_new.rttm"
next to the original file.
Usage:
python batch_double_rttm_viewer.py /workspace/comparison [--port 8766]
open: http://127.0.0.1:8766
