Is there anything out there to emulate 2-way crossovers on a PC with two output channels that is, one way or another, not limited to basic filters? Maybe something that can take an .frd file? I know SoundEasy and LspCAD have emulator functions, but I have no other need to add them to my arsenal, and it seems like there might be something available where I can just export an .frd for each channel/filter and make it happen?
Just tried these two, couldn't get either to run without crashing on Win 7 with my Tascam US-600:
Basic PC DSP loudspeaker crossover. Frequency Allocator Light
SPL Tools

Argh, I feel like I must be missing some obvious software option here... I have already FRD files of filter responses, just need something to apply one to each output channel in Windows.
Well I don't know what can do it directly, but I can do it via convolution in the JRiver player. You need to change the .frd file into an impulse wave file, but after that you can do anything you want. Also rePhase can generate the impulse for you from scratch because it has some built in filters, EQ and phase adjustments. With that impulse you can use a convolver in JRiver or some other player. Or you can import your .frd files into rePhase to make the impulse wave.
To make the convolver route the filters to the channels you want you'll need a little text file with the routing. It's easy to do.

I was just trying to figure out how to do exactly that with foobar2000. So far I haven't figured how to use a separate convolve for each channel. Not sure if I need a convolve plugin that works with separate impulses for each channel, or if I'm supposed to be able to use another plugin to route channels through separate instances of the convolve..
For instance, this person seems to be referring to what I'm talking about, but I guess I'm missing something because the foo_dsp_convolver config just asks for a single .wav file, and I don't see how the zillion-channel matrix mixer helps:

If you check the convolver help and wiki there are some good examples there of the test scripts. Simple stuff. I think you can use a mono file for a pair of channels, it just applies the same to both. That should be in the wiki. If in doubt use a stereo file with the same impulse in each channel (AKA, dual mono).
If you don't find, I'll see what I can dig up for you.

Alright, I was being dense and not thinking in terms of stereo impulse files, so that solves that part. I can't seem to find a tool to import an frd and export it as an impulse wav, though.. Looks like sox can probably do it, but command line... ugh.
