You can have your reference track on one channel and your track to be mastered on another channel. The best mastering process will be on your iPad no doubt, but you can fake it on the iPhone with FL Studio Mobile 3 (no matter if you mixed down your track in FL Studio Mobile 3 or elsewhere). I finally got my SIM card yesterday and have had some time to experiment with the apps I have. Very keen to know what you think of those options? From the product page looks like BM3 will have compressor, limiter, and a six-band (parametric) SV filter (not sure if that's the same thing as EQ) in the box.Ĭaustic, FL Studio, MultiTrack DAW, Music Studio, and NanoStudio also all come with some mastering features in the box. On iPhone, for AU hosts we have AB3, AUM, and GB, until BM3 is released. As far as I understand AUs like Blamsoft, Flora, Klevgränd, RF-1 and RP-1 are for other types of FX, not any of these categories per se. There may be other non-AU apps that fit the categories but I haven't been keeping track of those. The following are all AUs except for the AUFX series which hopefully will be in the near future. I think the real question is less about what sort of 'mastering' tools there are, and what are the best EQ, Compression, and Limiting for the iPhone. With the right host and proper options there, I don't think there's anything reason you couldn't do a good job on the iPhone too. I do need to look into what sort of options there are for iPhone EQ and Limiting though. I haven't seen anything released since then that would make me change my mind though.

For iPad based mastering, this is what I thought a couple years ago: I don't use Garageband myself, at least not in a long time, so I'm honestly not sure.

Since you're a professional mastering engineer, do you have any opinions on how close you can get to a good sounding master with GarageBand? Are there any other iOS apps you like for mastering? I'm sure you're right, at least for anything published.
