Some examples
 
  -  Recommended usage: Encode a WAVE-file myfile.wav 
    to a bitrate of 128000 bits/s, writing to a plain bitstream myfile.mp3 
    and using high quality mode:
  lame -h myfile.wav myfile.mp3 
  
  -  Encode a plain PCM stream (2-channel, 44.1 kHz) 
    to a plain 56 kBit/s Layer-3 stream, using the encoder as filter
  lame -r -s 44.1 -b 56 - -
