Tried it, thank you. It makes a file, but I presume I have the options
wrong (or I need a compile without 'libsndfile') because the result sounds
awful.

 | lame -r -s 48 --little-endian - lame-test.mp3
WARNING: libsndfile may ignore -r and perform fseek's on the input.
Compile without libsndfile if this is a problem.
Assuming raw pcm input file
LAME 3.100 64bits (http://lame.sf.net)
Using polyphase lowpass filter, transition band: 16452 Hz - 17032 Hz
Encoding <stdin> to lame-test.mp3
Encoding as 48 kHz j-stereo MPEG-1 Layer III (12x) 128 kbps qval=3
