Line 34:
'''Linear pulse-code modulation''' ('''LPCM''') is a specific type of PCM in which the quantization levels are linearly uniform.<ref name="LOC_LPCM" /> This is in contrast to PCM encodings in which quantization levels vary as a function of amplitude (as with the [[A-law|A-law algorithm]] or the [[μ-law|μ-law algorithm]]). Though ''PCM'' is a more general term, it is often used to describe data encoded as LPCM.
A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the [[sampling rate]], which is the number of times per second that samples are taken; and the [[Audio bit depth|bit depth]], which determines the number of possible digital values that can be used to represent each sample
