Far shore is a real field recording of the sea heard from a distance, at Puerto Escondido on the Pacific coast of Oaxaca, Mexico. Leonardo Santiago made it and released it under CC0 into the public domain. Its source gives no date, so greensound shows none rather than guess one.
Where is Puerto Escondido?
Puerto Escondido is a town on the Pacific coast of the Mexican state of Oaxaca. This recording is of its sea, heard from far enough away that individual waves blur into one steady wash rather than distinct events you could count. Its source names the town and nothing more specific — no beach, no landmark — so that's as precise as this page gets too.
Who is Leonardo Santiago?
His Freesound profile describes him, in his own words, as a Mexican phonographer — a field recordist. He released this recording under CC0, a public domain dedication that lets anyone use it for anything without asking, and greensound credits him by name anyway, the same way it credits every recordist a source names. His profile states nothing more about how or when he made this particular recording, so greensound adds nothing more either.
Near waves or far waves?
Beach waves, also on greensound, was recorded close to the shore at Punta Allen, on Mexico's Caribbean coast, so individual waves rise and fall as distinct events, one after another. Far shore is the same kind of subject, the sea, heard from much further away, on the Pacific side, so it reads as a single low, even wash rather than waves you could count. The original recording runs five minutes and fifty-seven seconds; what plays here is cut to a 20-to-40-second window, with a 2-second equal-power crossfade baked into the loop so the seam can't click. Played quietly, it sits near the edge of hearing, more a background presence than a foreground sound.
