README

What is this project about?

  • Audio Unit is an Apple audio plug-in format.
  • Audio Units can be used in popular DAW's for audio processing and as synthesizers
  • Pd++ is a C++ library based on Pure Data
  • See Pd++ repository
  • You can develop audio units using Pd++, this project is an example

How do I use this project?

  • Download Pure Data if you have not already Pd
  • Download or clone the Pd++ library and get familiar with the syntax, object model and classes. The classes are all based on Pure Data's Vanilla objects.
  • Download or clone this project and study how I used my Pd++ algorithm
  • Create a new Xcode project with the same settings, files, and formats
  • Build your project, fix errors, and now you have your own AU

Notes

  • You will need to download the Audio Unit SDK from Apple AU SDK
  • Import all of the required files or provide Xcode with the path to the headers to Apple's AUPublic and PublicUtility folders.
  • Import the proper frameworks for AU, for this project they are * CoreAudio * CoreServices * AudioToolbox * AudioUnit
  • Make sure to change your .plist, .exp, .pch and *Version.h files to fit your plug-in
  • This project has two .exp and a .r file that were for a 32-bit build. If you only plan to use 64-bit plug-ins then you can remove the AUssb.exp and AUssb.r files.

I have only tested this plug-in using a 64-bit build. I have tested it in Logic Pro X, GarageBand, and AULab and validated it using auval. Good luck with building for 32-bit. It seems Apple no longer supports the development side of that very well. 64-bit works fine however.
