Non-uniform quantising logarithmic compression




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).
