Finds every hit, decides for itself whether the attack is fast or slow,
trims to a zero crossing so nothing clicks, normalises, names everything
and hands you a zip. The only job left is deleting the boring ones.

How it decides. For each hit it measures the time from onset to
peak. Under 15 ms it treats it as percussive and barely fades at all,
because the click is the sound. Over 600 ms it treats it as a swell and
uses a longer fade, losing a little front tail to guarantee a silent
start — usually the right trade.
