What's up with this DVD audio?

[feralicious]

It doesn't have all the info like kHz and kb/s:

Did i just find your G-spot? :)

If you did it's not all it's cracked up to be.

anyone?

Besides Dennis and Jeff and their g-spot comments. :rolleyes:

Hi Nina,

I'm not a PC user (so therefore not a GSpot user - no comments from the peanut gallery!), but I think I read someone make a comment that if your audio is PCM then that information will not show up. Maybe test that theory out on a couple of different DVDs if you have a couple with that type of audio.

Okay, so it looks like PCM is top of the line audio? The L in LPCM must mean something then, I can't imagine the audio and really good video quality fitting on the DVD. More googling...

PCM

Cons: The main disadvantage of Uncompressed PCM (WAV or AIFF) audio format is size. It stores all audio information without compression. It's a recommended format for audio editing. Do not use PCM in final versions of DVD. Only leave it as PCM if final disc size is unimportant or if unusual distortion occurs from AC3 or MP2 compression. Common bitrate is 1536k.
Pros: The main advantage of the PCM audio is excellent quality. With PCM you can preserve all audio frequencies (even outside the range of human hearing).

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.

I'm reading and learning! :D

I've been lurking, sorry I don't have the answers for you but I am interested.

:hmm: So.. my .wav files are PCM encoded for show X.. and show X consists of 1.6gb in .wav (PCM). I should be able to burn that show to a single DVD and play that DVD back on a player that supports .wav payback, correct??
:confused:
