I wish I had thought at the time that I was recording reusable sound effects, but unfortunately I was more focused on hanging out with my friends and documenting the gadgets on video. That I got anything usable at all on the sound track was more of an accident, so I was happy to upload it here. That said I'd like to go back sometime with better equipment and the intention of getting clean audio and do it properly.
Perfect as a component for the sound of a large object falling down stairs. The noise is easily masked, and I think it can be filtered in any case. And your other balloon recording (balloon.flac) is hilarious. Thanks!
