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.

Sean Costello teaches how to code a Reverb
I bought Desktop ValhallahDSP reverb on the recommendation of @jonmoore and became aware of Sean Costello's creativity with Reverb coding. His DSP code is used in the IOS EOS 2 Reverb.
He has decided to blog his advice to anyone interested in understanding the options available to code a reverb. Of course, the advice can be generically applied to music app development.
TL;DR - use the Juce framework and for DSP code use C++.

For those that don’t already know, his most recent free plugin Supermassive is sooo good.

Amazing dev to support on desktop
Get all Valhalla plugins. The delay is insane. Vintage Verb is epic and Supermassive is divine.
Sean Costello is a master of his art and sells his plugins at a very reasonable $50 a piece (which for the quality, is insanely low for desktop plugins). But his three free plugins are just as essential as the ones he charges for. If you start with the free ones alone, your creative FX arsenal will be provided with a booster shot of real worth.

It recommends a list of academic papers on acoustics covering decades of research.
They were talking about "colorless reverbs" in the 1970's. I'm curious to see when the
papers switch from analog to digital designs.
