There are a couple of issues with the popular foobar2000 plugin, foo_dsp_xover. Among them is the fact that the delay behaves oddly and is not applied on a per-channel basis. Since it's open source, I'm wondering if there are any updates to this software floating around in the forums that haven't been uploaded to the sourceforge site? Alternatively, is there a good 8-channel delay plugin for foobar2000 that could work in conjunction with the crossover plugin?
