LPCM
From Just Solve the File Format Problem
LPCM stands for Linear Pulse Code Modulation, also referred to as Linear PCM. It is a digital audio encoding, using pulse code modulation (PCM) with linear quantization. PCM is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code. PCM has been used in digital telephone systems and LPCM is the standard form for digital audio on audio compact disks.
