The kind of compression often applied to a sound waveform.
Logarithmic compression is a good match for the human ear's
sensitivity but cannot handle zero amplitude (for which the
logarithm is negative infinity). There are two standard
compression functions which give a smooth transition between
the logarithmic function and a linear segment passing through
the origin: mu-law (North America) and A-law (ITU-T).
