[linux-audio-user] Stereo delayed crossmixing

Hi, New to the list and looking for a package to do stereo delayed crossmixing. What I mean by this is to take a stereo signal (from CD, by preference) and send right and left channels through delay lines, individually adjustable to sub-millisecond delays, then mix each delayed signal with the un-delayed signal of the opposite channel, then feed to the output device. Processing in real-time (latency end-to-end is not an issue.) Note: there is *no* feedback of delayed signals - echo is not what I'm after - this is strictly feed-forward delayed crossmixing. Frequency-binned multiple delay lines would be an interesting add-on. I've been searching for packages capable of doing this - if anyone is familiar with something that would do, I'd be really grateful for advice. TIA, Andrew
