So I was kind of excited when I saw "AI" and "Mastering" in the same sentence. For me (as I suspect for a lot of musicians) mastering is the hardest part of post-production work. So I was really eager to try out LANDR, I figured this "artificial intelligence" will probably know how to master my songs better than I do.
Well the first red flag went up went I realized it had to upload the song to the LANDR site. With my Internet connection, with my son hogging the bandwidth with his video games, uploading a 4 minute wav file took way too long (over 7 minutes). The second red flag is finding out that you have to pay the highest subscription plan, just to get a decent choice of options.
I already shelled out a bunch of money recently upgrading to Izotope's Ozone 7 Advanced. And I get by with the dozens of presets it offers (usually tweaking them a bit to get the sound I want). But even if I didn't own Ozone, Sonar Platinum offers many off-line mastering tools that are available within the program itself...immediately ready to use.
But the most important reason I won't be using LANDR, is ironically because I realized I do NOT want to use the AI to master my songs. Even though Ozone comes with presets, you still have to tweak the various modules to get the sound just right for each individual song. And working hands-on with compressors, exciters, EQ's, and all the other mastering tools, you are actually LEARNING how to master. I have learned a lot from using not only Ozone, but with all the other tools within Sonar. And I think mastering is an important part of the music production experience, and from what I've seen with LANDR, you are missing out on "getting your hands dirty" and learning how to do it on your own. But I guess some folks just want to write their songs, and press the "Doesn't Suck" magic button, to make their songs sound better. In which case, if you don't mind waiting for the upload, and don't mind paying extra money for tools you already have, then LANDR is probably something you'd want to invest in.
I think a lot of people were surprised at the added expense, and ultimately disappointed that this new feature is not free. Maybe to ease the sticker shock, Cakewalk should add a little footnote on the Updates page, stating that LANDR costs additional money to use.
(I haven't read all the previous posts in this thread, so I apologize if I'm repeating something that was already said)
