The song is a borderline result sent for review. Scores are uncalibrated model evidence; a low score does not certify an instrumental. Slight decoder/backend differences can move a score near the threshold between review and voice-likely.
All 217 URLs were attempted. 203 recordings were analyzed; 14 audio URLs remained unreachable after a retry. Failed downloads have no confidence score. Each successful recording was sampled for up to 30 seconds. The first pass and retry took 512 seconds of batch execution.
This is a dated snapshot, exported 2026-09-17T12:26:17.364Z. Scores are screening evidence, not listener-confirmed vocals or measured detection accuracy.

The controls exercise a sung recording, spoken narration, and two Musefi excerpts. This is a functional smoke test, not a labelled catalogue benchmark. The two Musefi excerpts have not been independently labelled by a listener. The requester’s four listener-confirmed problem tracks were not supplied.
Open the four-track demo and click Run demo scan. The first run downloads the model; processing time depends on your device. Keep the tab open. Use the included command-line scanner for larger queues.
