Hello,
I'm working on a project in which the requirements are to take a
USB Audio compliant device, and for the vendor's specific product have
some very simple DSP related tasks performed on the incoming audio
before it is reported as an input device. Our windows developer has
finished his version using a Filter Driver. Could someone point me in
the right direction for the Mac side of things? I've been reading over
the device driver sections of the documentation and I get the
impression I need to use a Device Interface? I'll admit to be being a
bit new at the lower level stuff, so any help is greatly appreciated
here. I realize I'll need to go over things with a fine tooth comb,
being I'm going to be communicating with some things beneath user mode.
Thanks in advance.
Cheers
~Rob
