I have a simple 4 channel ambi decoder programmed into the
built- in mixer of my computer's sound card. I just choose the
preset, play
the 4 channel B-format file and it decodes it for me.
Would you mind giving out the details of this, or is it proprietary?
Thanks,
Bill
sure...
I use an RME fireface audio interface. It has a built in Matrix mixer
which
allows you to route and mix any software output (or hardware input) to
any hardware output. Because you have quite fine control over the
mix levels and you can flip the phase, you can set up a simple
decoder in it.
(no shelf filters though!) I often use it as a rough-and-ready ambi
monitoring
setup so that I don't have to do it inside, for instance Logic or
ProTools.
Also, it happens in the interface and doesn't use any computer CPU.
and my
laptop is very old, so that's very useful!

the fireface sounds great.
