Digital Audio Control Mixer
I want to make a device/mixer that can digitally control the volume, balance and mute (on/off) of several stereo line level audio inputs and outputs. I need to be able to choose which outputs each input signal will be sent to. I also need a master volume and mute control that will control all the outputs at the same time.
I want to be able to control this using an IR remote control but maybe from other things like a PC or maybe an iPhone.

Here are some examples of what I need the device to do:

If it were a non-digital mixer (i.e. it had manual controls), they would look like this:
**broken link removed**
I can think of two ways to do this:
1. Use digital pots or volume controls for the volume, (I don’t know if the pots will do or will u need the real thing made for audio?), Use relays or transistors to mute the signal OR just put volume to zero? For balance use extra control or individual volume controls for each stereo channel (L/R)? Use a micro controller/processor of some sort that will interface to the controls (volume IC, etc)?
2. Use some sort of digital audio processor?
