thank you bill,
i did look at the sampleEffect-project but I've tried to compile
SampleEffect (the Project in SampleAU) with XCode 1.0.1 and it exited
with 2 errors:
../AUPublic/OtherBases/AUEffectBase.cpp:50: error: conflicting types
for `kAudioUnitProperty_InPlaceProcessing'
/System/Library/Frameworks/AudioUnit.framework/Headers/
AudioUnitProperties.h:66: error: previous declaration as `<anonymous
enum> kAudioUnitProperty_InPlaceProcessing'
thanks to the few but very helpful lines, itook a closer look. Now i've
removed the following anononymous enum deklaration from
AUEffectBase.cpp:
enum {
kAudioUnitProperty_InPlaceProcessing = 29
};
it is also defined as 29 in AudioUnitProperties.h.
I'm not quite sure what i'm doing here but now it compiles.
So i'm starting from here. Now i'm happy because i can get going . i
suppose i can now build my filter as an kAudioUnitType_MusicEffect
starting from SampleEffect. Seems almost straightforward.
Well I'm pretty sure you'll hear from me before i'm done.
cheerz and thanks
