so those with DVD-A discs (DO NOT confuse DVD-A with audio on a DVD Video disc) and a version of WinDVD that supports DVD-A (and preferably a sound card that can handle the increased resolution)

http://www.rarewares.org

just a side note... because of the higher quality (and possibility of multichannel audio) DVD-A rips are going to be much larger in file size (and really should only be compressed using a lossless format)

example [WITH_TEETH] (my only DVD-A disc)

using wavpack

CD 349MB (standard CD audio... stereo, 16bit 44.1KHz)
DVD-A 1.16GB (stereo tracks at 24bit 96KHz)

and for those interested in such info here are the bitrates for uncompressed audio...

Stereo 16bit 44.1KHz 1411Kbps
Stereo 24bit 96KHz 4608Kbps

now with DVD-A the bitrate can have a fairly wide range... because the sampling rate and number of channels can be different from one disc to another

with DVD-A all audio is 24bit but the sampling rate can be anywhere in a range from 48-192KHz

[WITH_TEETH] contains both stereo and 5.1 tracks for the whole album... stereo is 96KHz while the 5.1 is 48KHz

for those wondering what is so great about DVD-A

CD-DA is 16bit 44.1KHz this means a dynamic range of 96db and a max frequency of 22.05KHz

DVD-A is 24bit and anywhere from 48-192KHz which means it has a dynamic range of 144db and the frequency cap is anywhere from 24-96KHz

what does this all mean..

well dynamic range simply allows for louder audio without clipping

and frequency range.. well higher sampling rate means more treble extension mostly here's a visual representation

this shows the cutoff very well as well as crappy jpeg compression

That is definitely impressive.

I've always been a fan of DVDA, I didn't know you could actually do it, or anyone else was a fan of it here. Why is this on the music forum?

because DVD-A is a music format....

and last night out of curiosity i ripped the 5.1 tracks

2.70GB wav
1.70GB wavpack (lossless)

The only DVD-A I have is the one that came with my Audigy 2. And I gave it to the dude who bought the sound card from me.

updated the comparison images

rarewares has taken the links down... damn lawyers

How long are DVD-As?

it all depends...

sampling rate, number of channels... also if the tracks are uncompressed or MLP encoded (lossless compression used on most commercial DVD-A releases... the encoder costs $2500)

and then if it's a single layer or dual layer

example... [WITH_TEETH] dualdisc DVD side has...

AC3 encoded dolby digital stereo and 5.1 (not sure about the bitrate) for standard DVD players

MLP encoded 24bit 96KHz Stereo and 24bit 48KHz 5.1 for DVD-A players

The Hand That Feeds video
interactive discography thingy with music and video clips

now burning a DVD-A with software that can do DVD-A authoring won't be able to fit as much on a single layer due to a lack of MLP encoding (again that encoder is really expensive)
