Decompressed? You mean decoded back to WAV?
No, I don't think so.
Not in Winamp (2.x / 5.x), no idea about Winamp3 though...
Monkeys Audio supports .APE (and .MAC ?) files only
SHN = Shorten Lossless Compression
The ShnAmp plugin is here
Note, there's a Winamp plugin for 2/5 and also a Winamp3 component available.
CUE files are not audio files. They are cuesheets, which provide index pointers to tracks if the cd was ripped into one large file (as opposed to separate tracks).
eg. filename.cue matches and works with the appropriate filename.mp3
MP3Cue plugin is here
BIN files . . . afaik, these are NOT audio files.
BIN usually stands for Binary.
It's possible that these files have got the wrong extension. Not sure...
They could be raw audio data, or a cd image, or they could be related to the CUE cuesheets. Anyone?
The only seemingly relevant info I could find was this
