Music mood card (BGM · jingle · video sound track)

Turns a music file or a video's sound track (5 s to 5 min) into an easy-to-read mood card — tempo in BPM, energy and brightness, the estimated key, an energy flow with quiet, medium and loud sections, the most intense, calmest and biggest build-up moments, two mood axes (calm–intense, dark–bright) and one or two mood words marked as an estimate. Made for people choosing background music for ads, shorts and events, not for genre, quality or copyright judgement.
