A friendly hello and thanks for your time and reply! I’ve obviously searched my mail accounts, not the LANDR one, shame on me :-)! Concerning the service offered and a “dunno” as a reply, while offering an online service available for thousands of users needing some mastering, meaning that: a) are not familiar with such complex process or b) don’t have the expensive devices in many cases, in a context of newcomers, hobbyists etc… those “unprofessional” programs should be well familiarized with, and if not, find out; how do we feel when on our inquiry as customers we get an “ehm, ehm, whoopss…”? The credibility is gone, my mixed set too, not to be found in mastering history at LANDR, not in wetransfer or cloud of sorts; finally I have a particular satisfaction in creating a credible track or mix with a silly cell or software ( not referring to MM, which led me to FL12, Acid, Audacity, Spreaker and LMMS ) reaching better results in listens than certain nu jazz producers, me as a perfect professional ( meaning I was and am paid for my sessions ) nobody. So if the approach to customers is not competent, welcoming, helpful, advising to load heavier WAV files and not considering the eventual intricacies related – BTW, the couple of mastered tracks they sent to me, vanished from my inbox as well – I have to call it curtains, since the time wasted won’t be paid which ain’t amusing at all, isn’t it? Best regards and success, Sir 😉
