Recording using XDJ RX

Hi guys, quick question.

When recording onto the USB 2 port I find that the files are created in a WAV format.

Is there anyway to change this to MP3 instead?

I regularly upload my mixes to soundcloud or mixcloud but these do not allow WAV format uploads and it's starting to get a bit tedious reformatting the files.

A swift response would be really appreciated.

Thanks

Danny
