This is really a surprise! You really don't need to think of conches when you play it. It is indeed somewhat meditative, reminds of a recorder / flute / soft reed instrument, and the conches were blown by a musician, who collected them. There is a free version (which I tried here) and a full version, which I probably will buy later. You have lots of otions for tweaking, too. And two .nkis, mono + polyphonic.
