Arbitrary switching of a large number of analog signals
If you need (up to) the full 24 audio paths through then you need 576 switches (assuming mono), in whatever form.
The AD8113 seems comparably reasonably priced but you'd need 4 to get (up to) 32 x 32 and that's about $120-$150 just for the chips.
Analog crosspoint switches don't tend to be cheap. I did an audio/video switcher with similar chips some years ago, controlled by a micro. They did what the datasheet claims, kind of boring in a good way.
