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.
PhaseDelayArray by Neon Silicon (FREE)
PhaseDelayArray is an Audio Unit, or AU, for iOS. This application is simply a container for the Audio Unit and also serves as the documentation for the AU. PhaseDelayArray must be used in some sort of Audio Unit host or DAW application.
PhaseDelayArray is a bit of a strange effect. O.K, so, what is it? PhaseDelayArray has three effect units chained together in an interesting configuration, and one of these units is just a little bit twisted. The first unit consists of a sequential array of vibrating (oscillating) reverberation sections. The oscillations can be tiny or huge. The reverb depth can be tiny or huge. The overall effect can be subtle or HUGE. It can create a wide range of sounds. The second section is a modulation unit. It takes the output of the PhaseDelays and whips it around, or up-and-down or back-and-forth. The final section is a feedback unit with the possibility of a lot of delay (up to 2 seconds). The mix section allows you to tap into all this strangeness in four different places. PhaseDelayArray can be used in mono-to-mono, mono-to-stereo, or stereo-to-stereo settings. Several of the features work best with a stereo output.
