AVS does run on foobar2000 and XMPlay, there's a wrapper plug-in called shpeck you will need to make it work. I also remember seeing something like this for Aimp3. Also there is a fairly new effort to run AVS presets in the browser. Not feature-complete yet, but looks very promising! https://github.com/azeem/webvs

Check out this port of AVS for the browser then – https://github.com/azeem/webvs It's fairly new, but the development proceed fast, so there's hope that all the effects of AVS will be supported soon. There's also a conversion tool for your old AVS presets – https://github.com/grandchild/AVS-File-Decoder But of course you can run the plugin in other players, including foobar2000, Aimp3 or XMPlay – http://faq.visbot.net/
