Just an update to the update I made of Apple’s filter demo audiounit project. I noticed that the last project I updated would no longer build right out of the box so this project just updates a few things, the details of which are in the project’s readme file. Here it is: http://solamors.com/FilterXcode6.zip
The details of updating the older project are in the old post here -> https://alexkenis.wordpress.com/2014/01/23/apples-audio-unit-examples-in-osx-10-9-and-xcode-5/ Most of it is still relevant.
Let me know if there are any problems and I’ll patch it up.
