What are you talking about? An FPGA implementation for what?

Ah, we'll the most common ways of writing code for FPGAs are in the form of an HDL; most commonly Verilog or VHDL. Programming/debugging is typically done via JTAG.

If you're not familiar with what an FPGA actually is, I'd recommend doing a Google search on it. In short, they are arrays of LUT's connected by programmable interconnects. Microprocessors contain a few functions (mnemonics) that can be used in succession to achieve a certain task, and FPGA's can do everything in a single clock cycle because you define the logic in hardware (you can create your own instruction set).

i see .so in effect these could be used to monitor events like the one in the pic and react , log stanalone from a pc.

That looks like a low frequency spectrograph. There are plenty of alternatives to an FPGA if you want to analyse audio signals in real time, but you could certainly use an FPGA to do a fast Fourier transform in conjunction with an analog-to-digital converter, along with other digital signal processing steps.

I think Dave mentioned that he isn't particular interested in HDL and FPGA implementation beyond board layout, but there are plenty of resources out there. You could try fpga4fun.com or FPGA Prototyping by Verilog Examples.
