Re: What's up with this DVD audio?

Okay, I realize I'm talking to myself here, but maybe it will help someone else down the line. Like Dennis or Jeff might read it while looking for more gspot stuff and actually learn something.

Linear Pulse Code Modulation (LPCM) is a format that is a popular choice in the Music Production. It is an audio production technique that, without compressing the sound data, simultaneously samples and captures analog signals and transforms them into digital signals. This uncompressed digital audio is the same format as what is used for Music CDs (samples 44.1 kHz at 16 bits per sample). LPCM has been defined as a part of the DVD standard, but most average DVD players can only support 48KHz/16bit capability. Only relatively more expensive players have built 96kHz/24-bit capabilities. However, CyberLink strives at providing you with the ultimate digital video entertainment solutions, and that's why we made the decision to enable PowerDVD XP 4.0 to fully support 24-bit/96KHz LPCM audio playback.
