plugin developer kit?

Your Mac comes with XCode, which has sample templates for creating Core Audio components.

There are also docs on developer.apple.com and example projects, should be all your need, short of joinng the Core Audio develoeprs mailing list, as long as you have coding, general audio plugin and DSP development experience.

As Bee Jay said, you need Xcode, C++, and the CoreAudio framework. There are numerous examples in /Developer/Examples/CoreAudio/AudioUnits. Depending on whether you want to write an effect plug-in (FilterDemo) or an instrument plug-in (SinSynth).

The CoreAudio API is fairly straight forward. The basic steps are 1) initialisation 2) register parameters 3) process each audio frame. The host application, such as Logic, is responsible for drawing the generic parameter view. You can of course provide your own GUI with Cocoa (preferred) or Carbon. The host then 'ticks' your process function for each frame of audio at the song's sample rate. This is where you do your DSP.

I recommend working through Apple's tutorial of a gain effect plug-in here:

I have a couple more samples here which use Xcode 2.4.1 and pass the latest auval.

Hi,

Your website keeps sending me to the iTunes store to buy your record.

I'm using Safari Version 2.0.4 (419.3)

That *****... I hope your plugins really work, unlike your website.

Cheers

shurgs - worked for me on Safari.

Maybe your computer is mutineering..? 😉

yeah...that's probably it.

I'll go whine in the Safari forum...not.

🙂

Then buy his record man! HELP a musician! jejeje

That's weird. The link I posted was definitely to the right part of my website.

I have a friend who is using the free AU making application called 'SonicBirth' which is available at:
http://sonicbirth.sourceforge.net/ and their forum is at:
http://sonicbirth.mi05.de/

It's free and it's a UB application. It comes with some pre-made AU's as well as some examples to help get started. A few people have already released a couple of interesting AU's such as a 'Stutter-type' AU, a vocoder and recently a sidechain compressor. It seems like an easy way to dive into the world of developing AU's since the learning curve isn't quite as high as learning more traditional coding methods.

Peace - xpander

Yes SonicBirth is great not only because of it's modular synth like design that lets you build your own plug-ins but also as a useful open source project. From memory I think most of it is in Objective-C.

The code repository is here:

http://sonicbirth.sourceforge.net/source.shtml

My synth plug-in (which does work, as does my website btw), is also on SourceForge.

It's in C++. As far as I'm aware there aren't too many OSS instrument plug-ins in AU format. I was hoping the OP may find this a useful reference.
