This sounds very much like a b4 file being played back in a b3
decoder.  Beta 4 implements odd-sized LSP filters that beta 3 can't
decode (the real bug is that beta 3 doesn't realize it can't decode it
and makes a high-dB pop).

Make sure that the Winamp you're using isn't a beta 3 version, and let
us know if a b4 decoder also produces the problem.
