For Audio, I used a hardware solution.

I bought a used Roland 160 (rock band) mixer.
<http://barrie.kijiji.ca/c-buy-and-sell-musical-instruments-Roland-M-160-W0QQAdIdZ147047989>

New (discontinued) $1000; now about $100 on eBay.
  * It has high quality audio
  * 16 input channels
  * 2 output channels (stereo, you have two ears)
  * each channel can pan left or right
  * each channel has input attenuation to avoid overload clipping
  * each channel has multiple sends to route thru filters,
         computer audio in's, tape recorders.
  * headphone jack, master volume
  * multiple impedance inputs
  * rack mount

Each radio has its own channel.
The audio out from the Roland 160 goes thru
a rack mount stereo graphics equalizer.

Then it goes thru a rack mount Nady HPA-4

four headphone set amplifier/controller.

Plugged into one of the headphone jacks is a rack mount
stereo amplifier and two speakers.

The whole audio chain is HIFI audio quality, the graphic
equalizer can be used to control SWL hiss and rumble.

This way, I can use any radio and it all cones out my
headphones or speaker and to a tape recorder. Two radios,
panned left and right, or all radios if you choose. I can send any audio
thru anything just by twisting centrally located knobs.

I have a similar setup for audio out to transmitters, with
ptt control and impedance matching and isolation transformers
to avoid ground loop problems.

Current project is to add mute to the receiver chain, controlled by
the transmit ptt.

Sincerely

p.s. Tuning is controlled by individual programs on the computer,
each according to the hardware, or by hand. I also have a bunch of scanners
the just scan..
