Upload your track. The engine marks the passages that are loud and recur as exact sequences — that's what a chorus is — and hands you the three best windows with instant playback.
WAV, MP3, FLAC, AIFF, M4A or OGG up to 30 MB. Your file is analyzed and deleted — we keep numbers, not audio.
You also get tempo, key with Camelot code, and five measured character words — useful for tags and pitch copy.
