Presumably there's a WAV file (or several) somewhere with the DJ voices. What if one were to locate this file and replace with an empty WAV file, similar to the silent startup files? Or, to be more exact, where might one find these files?
I PM'd Treeag with this question over at MTS2 yesterday since she's an excellent modder and has done one with sounds. She doesn't have time to do this mod, but she said:
Yes there's a sound file for that DJ of course, maybe somewhere in sfx.package or misc.package. The thing is, those packages are pretty much a big mess. There's no label whatsoever so to find it you might have to extract all of them and listen to each of them to determine which is which. Once you find it though, you'll just have to take note of the instance number and then make a new blank mp3 file and import it into a package. Hope that helps.
Perhaps it will; thanks again Treeag if you visit here.
I found the sfx files under Program Files/EA Games/The Sims 2/TSData/Sounds, and randomly extracted one and tried to listen to it. My Windows Media, however, said it didn't support that type of MP3 file and it might have been compressed. If anyone has an EA friend or an old programmer tech handbook that an EA/Maxis would have, it should have the instance number. From that point making a Shut Up The DJ hack would be a breeze for a sound person (unfortuately I'm not).
