DTS to AC3

[King_Diamond]

Is it possible to convert a dts audio stream to ac3? Is there any software that can do it?

Not directly (afaik), but several programs can decode DTS (azidts via winDVD, dtsdec) and many programs can encode AC3 (BeSweet, surcode, etc.). The search is your friend ;)

What i wanted is a one software than can do it.

If there isn't i believe i will have to take the long way then.

Don't forget that both DTS and AC3 are forms of compression. Once an audio file has been compressed, if you uncompress it and then re-compress it, you are reducing the quality even further.

There is no single software product that can just transcode dts to DD

Hallo,

does anyone have experience with these programs and could give a hint which one give the best quality or is the fastest decoder?

Thx,
Dirk

fastest decoder?

azidts + windvd is a 'realtime decoder'
dtsdec a little faster but I am not really sure if the quality is fine!

Take a look at this (http://forum.doom9.org/showthread.php?s=&threadid=54738) thread for further informations.
If you want to decode a DTS48 (why?) you have to modify the there mentioned commandline switch -fs.

I want to downconvert a AC3 file from 448k to 384k. This transcoding process is not losseless, because I have to decode the files to PCM and then code them to the 384k AC3 file.
To avoid a quality loss, I want to try to take the dts-file as a source file, because a dts- file is encode at a higher bitrate than the AC3 source file.

What do you think? Is it worth to go this way?

yep, why not :o
make a small sample and let your ears decide :D
