I could record and post a lot of birdsongs, but frequently there are too many at once or there is a background noise such as a passing truck or car. That, and i can't identify most. Iphone, external mike, audacity.
A belch (or burp if you prefer) recorded in my home studio. Diet coke does wonders for creating these awesome sounds! perfect tie into to any file that needs a nice loud belch, or tone it down for the background!.
