Location of Export Audio presets?

Does anybody know where the "Export Audio presets" are kept in SPlat? I had some setup with X3 that I'd like to use in SPlat, but I can't find them. Also, have I corrupted the stock presets? For instance, "Share with Soundcloud - FLAC" calls up WAV format; "Share with Soundcloud - WAV" calls WAVEX; "Share with Soundcloud - MP3" calls Soundcloud - FLAC.
