This plugin enables you to use any input device with WinAMP, just as if it was a normal file (although you can't seek of course). The plugin is (almost) entirely configurable. This version has some new features, but mostly bugfixes and clean-ups. See my site for details on the plugin.
NOTE: There is a known issue with using the DirectSound support of this version (see my site).
Very useful plug-in that allows you to run any sound source through Winamp via Windows Line in. New version 1.51 allows support for presets plus other enhancements.
