I downloaded Radio Friendly's Flag sounds...

[Xection]

Do i convert the .wav files into mp2 files then replace them as one of the flag sounds?

Keep it in the file format that the sound files are currently, which are .mp2 for the flag sounds in live/legions/data/sound/game/CTF, so yes, convert them to mp2s and make sure that they have the same names as the current files (FlagCap, FlagReturn, etc) It is because when the sounds are needed it calls the directory for the sound, for example in live/client/scripts/audio:

new SFXProfile(CtfFlagReturnedSound)
{
  filename = "legions/data/sound/game/ctf/FlagReturn" @ $profileAudioExt;
  description = AudioGameEvent;
  preload = true;
};

" @ $profileAudioExt" I'm pretty sure this deals with the .wav or the .mp2 and figures out what to do with it. So, as a general rule of thumb, always convert files into the original format just to be safe.

You don't need to make a new thread for every question you have. This should be in the modifications section anyways.

It goes in your mod folder.
live/mods/autoexec
^Place it in there and you should be good to go.
*Some people may not have the autoexec folder so just create one.
