In certain applications, such as speech processing, it is common to use a logarithm computation, called a compressor, before quantizing. The inverse operation of a compressor is called an expander. The combination of a compressor and expander is called a compander.
The compand function supports two kinds of companders: µ-law and A-law companders. Its reference page lists both compressor laws.
