Talk:Linear pulse-code modulation
I don't think the LPCM article should be merged with Pulse Code Modulation. It is a computer media format, like MPEG, not just a data encoding format. Readers need to access it in relation to MPEG, not just in relation to PCM. ___
I agree -- I'm after a standard, ISO something something -- very much related to computer audio (DLNA specifically) so it's computer-type information that I'm after.
Source of the LPCM stub
The stub for LPCM was taken from an ad for a computer program from the company Cyberlink. This is the website:

I think this article should explain the difference between PCM and LPCM.
I tried to make clear the distinction between LPCM as a method of encoding and a file format, and added links to information about particular specifications. The existing article was referring to some particular implementation of LPCM used on DVD players which I was not aware of and don't know much about. But I wasn't really happy just removing this. This explains the bizarre section on standard sampling rates. Alexwright 14:37, 19 November 2006 (UTC)
Most DVD players only support 48 kHz/16-bit capability. Only more high-end players have built-in 96 kHz/24-bit capabilities.
"Most DVD players only support 48 kHz/16-bit capability. Only more high-end players have built-in 96 kHz/24-bit capabilities." is not correct. The official allowed formats for the PCM audio tracks on a DVD Video are:
* PCM: 48 kHz or 96 kHz sampling rate, 16 bit or 24 bit L-PCM, 2 to 6 channels, up to 6144 kbit/s
This means that there has to be a 24 bit decoder. But probably only with 16 bit accuracy in reallity. (8 bit of noise at the LSB)
But I'm not absolutely sure.
