10long_description          \
11        Shorten reduces the size of waveform files (such as audio) using \
12        Huffman coding of prediction residuals and optional additional \
13        quantisation.  In lossless mode the amount of compression obtained \
14        depends on the nature of the waveform.  Those composing of low \
15        frequencies and low amplitudes give the best compression, which may \
16        be 2:1 or better.  Lossy compression operates by specifying a \
17        minimum acceptable segmental signal to noise ratio or a maximum bit \
18        rate. Lossy compression operates by zeroing the lower order bits of \
19        the waveform, so retaining waveform shape.
