Quantization (sound Processing)
In signal processing and digital audio, quantization is the process of approximating a continuous range of values (or a very large set of possible discrete values) by a relatively small set of discrete symbols or integer values. This article describes aspects of quantization related to sound signals.
After sampling, sound signals are usually represented by one of a fixed number of values, in a process known as pulse-code modulation (PCM). Some specific issues related to quantization of audio signals follow.
