Repacking sounds

[Mistera91]

Is it possible, using this tool (or another one) to repack the audio files after modification, to change the sounds of a game ? I found « Fmod Bank Tools » but it didn’t work really well for me (could unpack well, but when repacked, the file was totally changed, and the game did not accept it).

If any of you has any information on modifying these files, it will be really appreciated !
(I don’t even know if I have the right file, it starts with 5249 4646 d8c0 b600 4645 5620 464d 5420 RIFF....FEV FMT , but at offset 000076e0, there is : 4653 4235 0100 0000 0d00 0000 1c0e 0000 FSB5............ stop me if I’m off-topic).

(sorry to ask for this on the issue page, there is no discussion page).
