Audio recording: lame is playing up

Hi,

Im having a funny little issue that someone might be able to prod me in the right direction with.
if I record audio using:

arecord -f cd -t wav > out.wav

Then the the audio recording is fine. However

arecord -f cd -t wav |  lame -x - out.mp3

Results in a file which plays back static. What might be going on?

What about:

arecord -f cd -t wav > out.wav; cat out.wav |  lame -x - out.mp3

       -x     Swap  bytes  in  the  input  file  or  output file when using
              --decode.
              For sorting out little endian/big endian type  problems.   If
              your encodings sounds like static, try this first.
              Without  using  -x,  LAME  will  treat  input  file as native
              endian.

So the '-x' option seems simply wrong here.

EDIT:
Though it is said to be only relevant when combined with '--decode'. Strange.
