Sure. I considered software. But I'm a hardware guy. I like designing boards.
The rig was designed to do amplitude and phase simply. The final design will
have a $5 48 MHz microprocessor included. I'm using that one because of speed
and memory. When that proves out I might redesign for a $2 24 MHz processor.
Onesies prices at Mouser
Besides the hardware better illustrates the concepts than software. And I don't
have to tie up a PC if I don't want to.
I haven't priced everything out yet because the design is not done. I'd be
surprised if the cost was over $20 in parts for everything - power supply not
included. PCB extra.
Feel free to send this along to the list if you are inclined.

Engineering is the art of making what you want from what you can get at a
profit.
I like Polywell Fusion.

Did you consider software?
Is the audio on a Raspberry Pi fast enough?
I haven't looked at any details, but you can get ARM CPUs for ballpark of $5
on eBay. There is a good chance that one of their IO devices will let you
send raw bits via a DMA channel.
