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.
Palovue iMic - Mid/Side Stereo Condenser Mic Test/Review
Here's a test/review of the iMic by Palovue - a made for iOS lightning condenser microphone. It's like the Shure MV88 but has additional headphone monitoring and charging port. In the video I do a mid/side stereo recording of some acoustic guitar, then convert to stereo using AUM (thanks for the help @j_liljedahl) and Youlean LM Lite.
How do you think it sounds?
