My computer and literally EVERYTHING else on it is able to open mp3 files and upload them to their “site” or “game”, except for scratch, but why? Why do I have to convert my amazing mp3 files into wav?

It probably depends on a lot of factors. The most likely is file size/internet speed. It's common logic that larger files will take longer to download/upload on slower internet connections. If you compress the file, it'll take less time at an expense of sound quality.

I have another theory, although this might be a stretch, is that .mp3 files don't really work well with the Scratch sound engine, so it converts them into .wav.

I also just realized, but I think mp3 files take up more memory than wav, which means scratch probably has a limit to it's memory, like most things on the internet.

I don't think so. Usually WAV files are uncompressed, they should take up more space than MP3 files.

I don't think so. Usually WAV files are uncompressed, they should take up more space than MP3 files.

Maybe because scratch needs to uncompress the mp3, thus taking it longer?

I don’t really experience this problem. Maybe it is simply your computer, or the size of files you are trying to upload.

I don't think .mp3s are compressed in a way similar to .zip files. They shouldn't need to be uncompressed, and I don't think it's possible to uncompress them.
