La is a lossless audio compressor featuring the highest available compression of any such program. See my site on
US Foreign Policy.
  
 Comparison

Below is a comparison of La with the best lossless compressors available. All compressors are using their highest modes of compression. The test set consists of eight .wav files from a wide range of genres.

Note that this comparison is really focused on the compression performance - most of the below compressors have a number of faster modes (with correspondingly worse compression) which I haven't bothered to include.
