Software Mixer for Mac?

[northernpaul]

Hi,

Does anyone know if there's a Mac version of the Vista Volume Mixer?

See

This is the kind of software that I think would be very popular, and I for one would definitely pay for a good Mac implementation. Is something like this technically feasible for Mac programmers?

Cheers
