The Joysound Karaoke app for the Switch pulls in music from unencrypted HTTP CDN... and this file format is a perfect example of the kind of failure sadly common in Japanese software development.

Of course, there are already a zillion container formats available that will do this for you. But Japanese developers love to reinvent the wheel, so they did. Unfortunately, someone clearly knew *about* multiplexing but didn't *understand* it.

I'm guessing someone was told to write some multiplexing tool. Unfortunately, the tool multiplexed the files in identically sized blocks. The files have a variable bitrate. this makes the multiplexing pointless, because the data is not synchronized *in time*.

Now, if this happened, I'd expect the people responsible for writing the playback tool to complain (if they knew what to expect). Unfortunately, that would never happen in a Japanese company, because you don't want to make the other person lose face.

So whoever wrote the playback tool just worked around it, completely negating the point of multiplexing. And what could've been a file format written in the right order, with audio at the end, that can be played and streamed linearly, now no longer can.

Incidentally, the file format also mixes big-endian and little-endian sections. The audio section header is big-endian, but the mux frame headers are little-endian. So yeah, clearly multiple uncoordinated people involved.
