  • Thread-topic: shipping an aggregate device

Hi,
Currently we implement an AudioHardwarePlugInInterface, which aliases any audio driver on the system, by basically forwarding any audio requests onto the aliased audio driver.  However, since AudioDeviceRead() has been deprecated and the documentation recommends using an aggregate device instead, we are planning on rewriting our plugin as an aggregate device.
 
Does this sound like the correct approach?  Or are there any limitations that I would run into in terms of replicating this "aliased audio driver/forwarding audio requests" behavior with an aggregate device?  Is it possible to build the aggregate device into a bundle, so that we can ship it to the customer as a plugin?
 
I found a posting called "Creating Core Audio aggregate devices programmatically" at http://www.thismuchiknow.co.uk/?p=51.  Does anyone know of other documentation that would be helpful?
 
Thanks for your help!
 
- Alex
