Hello all,

I have created a very simple little reverb patch in pd which i now need to turn into an audio plug in.
I decided on developing it as a .vst plug in but ran into countless problems with juice amongst other things, so i'm going down the .au route.
I'm compiling in xcode (with little knowledge of C) and need to have the plug in done as soon as possible as it's for my final project at SAE of which the deadline is fast approaching. My first port of call is finding the core audio SDK online, and essentially carrying out the steps in this article http://sample-hold.com/2011/11/23/getting-started-with-audio-units-on-os-x-lion-and-xcode-4-2-1/

I'm just wondering wether anyone here has a bit of experience doing this?
Any and all help would be vastly appreciated. I massively underestimated this part of the project and i'm suffering because of it.

Thank you guys,

George.

get this https://developer.apple.com/library/mac/samplecode/CoreAudioUtilityClasses/Introduction/Intro.html#//apple_ref/doc/uid/DTS40012328 if you haven't already. You should already have the CoreAudio framework if you have a new version of Xcode. Apple development setup really differs depending on which Xcode/ system you're on, one of the reasons I don't want to put up with their ridiculous undocumented API change shenanigans. (I had a similar problem trying to program stuff with automator/applescript)
as for the implementation, simply use the same building blocks as in the pd patch (all pass filters, comb filters, other filters + whatnot)
Good luck

Thank you buddy, i now have all the relevant core audio SDK utility classes, a little unsure of what to do next with them. In previous versions of Xcode, they would have been put into the extras section of the developer files. That file no longer exists in Xcode 5.0.1 (what i'm using). As you said, everything seems to be undocumented. Not sure what apple is playing at, i've been stuck even creating the .au template for a little over two hours. I'm also not entirely sure where my pd patch comes into play with all of this.
Lots of questions, i know. It's difficult finding someone who has a bit of knowledge about this very specialised exercise.

Okay, so libpd is my entry for all of this. I have created a template for an .au in Xcode, took a few hours since apple removed CoreAudio and essentially any support for people compiling plug in's in .au.

My problem now is where to start with libpd?
