If you can't attend the session, why don't you use our secure online mastering service. It's as easy as that:
Upload your tracks here. (Preferably WAV or AIFF files at 24bit - or higher - and whichever sample rate you're working at)
Order and pay for your mastering..
Once we have received your payment, you'll receive a link to download your masters (PMCD masters and other physical format will be send by post at an additional cost).
