I was just wondering whether it is essential to put a compressor on the master output when exporting a project to mp3 ready to play out and send to other dj's just for pure loudness to stand up to the volume of other tracks. I normally just put an Oxford limiter on my master out as well as an EQ and Multimeter, is it essential to put a compressor on too? And why? I know there should be nothing put on the master output when sent for mastering but i purely want to know for a pre master, club/ radio play export if you should compress the file before limiting it. Many Thanks, Myles.
