Cut to a length

Ask for 7, 15 or 45 seconds and get the same track at the nearest musical length: its own opening, whole bars joined where both sides sound alike, and its real ending. Never stretched, never faded mid phrase.

Along The River, 2:35 in full, cut to 20.44 seconds with its opening and its real ending

Good to know

kind: "length" returns the nearest musical length (a 5-second request may come back at 6 to 8 seconds); video returns exactly seconds; loop returns a seamless loop of whole bars close to seconds. hit_at places the cue's climax on that second.
Listening (listen_url) needs nothing. download_url opens ainsof.io, which asks the person to sign in (Google or email) before the zip downloads. Edits are kept for 7 days.
An identical request within 15 minutes returns the same edit. Each caller (key, or address when anonymous) can have two edits in progress.
