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