Is it possible to register a 'fake" HAL audio device within my code,
so that I can route the QT Movie Sound data to that device.
In my application Isadora, I would like to be able to manipulate the
location of a QuickTime movie's sound on a multi-channel sound output
device connected to multiple (i.e., more than 2) speakers.
My previous method was to register a several Sound Output Components
for a specific HAL device, one SOC per each two channels on the HAL
device. But Sound Output Components are no longer used in QT7 -- so
that method is broken now.
Because you can assign a QT Movie to play on a specific audio device,
one idea that occurs to me is to create a "fake" HAL audio device for
each pair of channels, which would in turn feed the sound data to the
appropriate channels on the real HAL device. Then I could assign the
Audio Context for the movie to the fake HAL, which would in turn
route it to correct pair of channels on the real device.
Is this possible?
Many Thanks,
Mark
