I have been reading about DVD audio and beleive i am ready to try and make some DVD's to play in my car. What i want to know is what is the better format for sound quality?? Some of my friends sware by 5.1 and say that if i am going to play DVD-A that i should do it in 5.1. What kind of sound quality improvement will i see.

Thanks!

I thought they were the same.

 

dvd-a is a format.

5.1 relates to a sound system setup

 

they are

 

dvd-a is a format and is also known as dvd audio. 5.1 is the sound system like previously stated by yoolykeme. its 5 channels plus 1 sub. (front, center, right, left rear, right rear and 1 sub.)

 

So, if i make DVD-A cd's they will play over the center ch spkr in my TL??

 

DVD-Audio discs support several sound formats, one of them being 5.1 which means 5 distinct full-range channels (Front Right, Front Center, Front Left, Rear Left and Rear Center) and a low-frequency channel for the subwoofer (.1). It also supports stereo formats (two channels).

The term "5.1" is often used to describe Dolby Digital or DTS soundtracks in movies. The big difference between movie soundtracks in 5.1 and DVD Audio in 5.1 is the resolution of the sound. DVD Audio uses much higher resolution and bit-rate encoding for the audio channels since it doesn't need any of the available storage for video. So an audio soundtrack recorded in high resolution and mastered for DVD Audio will sound better than a soundtrack recorded in high resolution but subsequently mastered for a movie soundtrack as both Dolby Digital and DTS are compressed sound formats.

Hope this helps.

 

5.1 is a sound "presentation". It means "5 Channels of music" and "1 Channel of LFE", or Low Frequency Effects.

Digitally, a DTS Encoded file on CD or DVD-V, A Dolby Digital Encoded File on a CD or DVD-V, a Super Audio CD, and a DVD-Audio Disc are 4 ways of delivering a 5.1 presentation.

DVD-A's can be 2.0 (Stereo), 2.1 (Stereo with an LFE Channel), 4.0 ("Quadraphonic"), or 5.1. They can also include a DTS or DD encoded program in additional groups on the disc. These encoded files can be 6.1 as well (DTS-ES or DD-EX).

It does get confusing at times!

 

Still not clear on the above question.. If i am understanding correctly --- the music that i put on the DVD will have to be previously recorded in 5.1 for it to be reproduced in 5.1.?.?

Lets say that i have a bunch of mp3's that are compresses at a 128 bit rate. If i convert them back to a wave file and burn them to DVD-A. Will they play in Quad or stereo?

 

It will play through all the speakers, with the low frequency part of the source directed to the sub due to the cross over. All speakers on the left will be sourced from the left part of the stereo signal of the mp3. All speakers on the right will be sourced from the right part of the stereo signal of the mp3.

Thus, it will sound like 2.1, if anything, but technically its 2.0. Its only due to the cross over that the sub gets a workout.
