In addition to what was said below, in the particular case of file
references I'd recommend to use the AU file reference format
associated with kAUPresetExternalFileRefs.
This system will allow hosts to manage the assets associated with the
particular AU setting in the same way it manages the audio files
contained in projects, allowing for content-complete project backups
etc.
See Tiger's /Developer/Examples/CoreAudio/Documentation/AudioUnits/
AUPresetsAndFileReferences.rtf for more information.
Best,
Stefan

You overide the AUBase Get and Restore State calls, and just add
an entry into the dictionary (and retrieve it)... Something like:
SaveState
- add a path key where the value is a file path
RestoreState
- retrieve the path key value - and that is your file

Hi,
Can someone tell me, how I can make a property of an AudioUnit
persistent, i.e. saved along the parameter settings and also in
presets? To give the background: I am making a simple little
sampler to play my old amiga samples, and I want to save the path
of the audio file.
thx
Daniel
