Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Mastering for Spotify…What Am I Missing?
I’m noticing that my songs are significantly quieter than a lot of the music I listen to and I really can’t figure out why. I’m staying between -14 and -12 LUFS and leaving -2 to -1db TP headroom. I’m trimming off the inaudible frequencies, high and low. The songs sound great and the dynamics are preserved, they’re just significantly quieter than everything else.
