hi guys
when i want to export a mp3 file from project in adobe audition OK button grey out and a warning( The currently selected filter cannot save all files in the needed format (mp3)!) beside OK button will appear, what shall i do? but for other formats i don't have such problem. and i want export mp3 file from project directly and don't want first export a .wav file and then convert it to mp3.
thank you
