Archieving HD sound tracks

[Benjy]

Do I have any chance to resize, or more specifically to decrease the size of files type: DTS-HD 5.1 , DTS-HD 7.1 , or any other variants of HD sound track , in order to archive and store them on DVDs???
I am interested in getting a smaller size of the files but in the same time to keep as possible their original features, although I know that not much can be so ... But there may be someone who has an innovative idea or any efficient method of archiving.

Thanks in advance !!!!

PS.Could be accepted even an archieving option with reduction of certain parameters keeping in mind the idea to reduce audio file size in order to be easy archieved

Do you want lossless? You can archive as a flac on a DVD as data disc (won't be playable in most standard players, unless they specifically support flac). You typically get only ~10-20% better compression.

If you encode to lossy format, you can substantially reduce size, but also reduce quality. Audiophiles will never choose this, and would rather die.

If you have a blu-ray player you might be able to an "audio only" AVCHD disc, but it won't be any more compressed (in fact it will take more room with the transport stream overhead)

It's up to you to make the decision on tradeoffs, and what "quality" you are willing to accept

@poisondeathray

I don't have any sophisticated player.Just my PC equiped with 5.1 Creative Audigy video card ,so I'll be happy if I'll succeed to encode as FLAC ( even stereo ) , or to reduce as much as possible , to compress and archive as many on a DVD.
In this case what softs are necessary ???

eac3to

I don't know why you would downmix to stereo? That would be unacceptable to most people

Even a lossy 5.1 AC3 640kbps would be much better IMO, but of course it's up to you

Well, you can use eac3to to extract the AC3 or DTS core from Dolby or DTS HD sources. Those are not lossless, but keep in mind that during the pre-BluRay era there was no lossless DVD audio except for 2 channel PCM audio on some music releases so it's not like asking you go to back to VHS tapes.

not necessarily to be stereo ... that would be as a last option....
So ,which is best for my wish ???

eac3to ???
I don't like it it requires Libav / ffmpeg decoder or Nero 7 , or Nero Bluray , or HD that are not free( I tried few days ago and I failed to install it (
More , is hard to instal all these softs when you are noob like me (

I'll try BeHappy , coz I've already used it and I believe I learn it...
Am I right ??? I try do downmix to AC3....

I'm kind of in the same boat trying to archive my dvd-audio discs and get them in a less obscure format without messing with the quality.

@greymalkin So..???? Any ideea ??

don't fret Benjy. my post serves 2 purposes:
1) Shows more than one person is interested in this topic
2) bumps your thread.

Depending on which audigy card you have you may be able to decode dvd-audio with it which would allow you to play the dvd's from your computer provided you had the right software.

DVD-Audio allows 6 24 bit, 96khz channels or 2 channels at 24 bit, 192khz and the bitrate can go as high as 9.6Mbps, instead of 1.5Mbps for DTS (limited to 768Kbps on DVD-Video).

but once you see how much it will cost you to encode/author to DVD-Audio, you'll see it would be better just to buy a bluray player and make the AVCHD audio disc.
