When a band or orchestra sounds off, the director has to stop rehearsal and hunt for the problem by ear: which section, which passage, sharp or flat? EnsembleAI answers that from a single recording. Upload a short clip and list the sections; it isolates each section with Meta SAM Audio, measures every held note in cents against the ensemble's own tuning (not a fixed A440), and shows a timeline of who is out of tune and when, plays the worst passage, and gives rehearsal notes from Muse Spark. Directors can also ask questions in plain English ("Is the euphonium sharp on the third note?"). We tested it on Mozart's Clarinet Quintet with the clarinet made 25 cents sharp (detected about +22 cents, in-tune cello correctly left alone) and on a real duet where it found the known sharp third note (+33 cents). It is honest when a section can't be isolated instead of guessing. Live demo: https://huggingface.co/spaces/armaanmehta/EnsembleAI
