The sound recording of the environmental sounds certainly makes me appreciate having a better sound card. I listened to the recording a year or so ago and was not very impressed, to be honest. But now...wow!
Wonderful recording quality, the steps limit the use somewhat for people looking for "white noise from nature". It's nice to listen too, because it's like a audio poem, someone who can't talk taking you on a hike:-))
One thing I wish I had was the info on which device people record their stuff. It would be a nice feature on the site as well I think.
