need help converting audio file .opus (Taiko no tatsujin Nintendo Switch)

Post by fgh_761 »

Hi guys, I need some help...
The audio file container in that game is nus3bank ,which have a nus3bank header and an opus audio (cbr encoded) . Can use vgmstream for foobar2000 to play them.
But when I want to convert a wav file to opus and replace the audio in nus3bank, something goes wrong.
The opus file I converted, using opusenc.exe or LameXP etc, has some like...dummy data? And there's no same data in the game file. After I replaced it into nus3bank, it cannot be played by foobar2000 or the game
files.zip

The "dummy datas" have massive quantity, both them length is 7F
