Redo audio formats for songs

[PikaDude]

Some songs, such as the ACNL music is stored at a crazy 499kbps, despite the fact that the original soundtrack from the games files only exists at 299kbps. This is substantially larger than required and is also insane for any audio format. Songs need to be reduced to 320kbps maximum to reduce file size. Some songs for other games are also of lower quality than what's available and also contain audible artefacts of their lower quality.

Giving public visibility to the issue from the original project.

Opus actually makes the file sizes larger. The reason why they were much smaller is because no bitrate was specified, and ffmpeg decreased the bitrate to most likely 128kb/s. The ACNL soundtrack is stored at 499kb/s which is insane, and I'm pretty sure that the original soundtrack was only 299kb/s meaning that the bitrate was unnecessarily increased too. So I'm in the process of reducing them to 160kb/s vorbis files. You honestly won't be able to tell the difference.
