When I bought this game, since day 1, I have wanted to replace the horrendous voice acting for the TF2 characters. I did a big of digging into the files and did figure some things out, however I did hit some roadblocks. For one, I have no idea how to repack the .pck files in the Data\sound directory. Dragon UnPACKer seems to unpack the files just fine. Additionally, the audio format eluded me. Good news is, a Sumo developer let loose the secret behind the audio encoding: So with this information, I'm curious to know if there's a (re)converter for Wwise format. Additionally, are there any packers that can repack the files? Any help would be appreciated.
