The bumblebee is gone. I can make as many segments of this as you need and they will all be different. You probably need quite a few because you can't use MP3 for looping, or that was the case a few years ago. What audio formats can you use? This one is a fairly low file size for a 30-second clip.
The formats are ogg and/or wav. I can convert either of those to the others.
I *think* looping is supported. At least I've heard music/ambient sounds in ages that had no recognizable end. So make a clip a minute or two long. Also, please take the owl out of it. Just the birds and the bugs you have, please.
I'll remove the owl and create .ogg files. the .wav files that these MP3's were made from were very large, 1-2 MB in size. Its MP3's that won't loop because of the data info at the beginning of each file.
If you want more files just let me know. They are randomly created so are all slightly different. I can add water sounds (water lapping and rain) and wind if you have need of those.
