Is it possible to create DTS from MP3

[drwho]

And if it is how and what tools so I need please?
Thanks

Hi drwho,

From the "Glossary" (top left of the page):

"DTS is a multichannel audio compression format similar to Dolby Digital' e.g. like 5.1 sound.

...whereas MP3 is only standard stereo (2 channel).

So, although I'm sure with a lot of fiddling around with expensive tools, you'd be able to create multi-channels from 2 channels it wouldn't be true multi-channel audio (i.e. a different audio element per channel) - you don't have enough audio info in 2 channels to make 6 (or whatever) different channels.

So, in short, "not really" is the answer. And, even if you could / did, I'd guess it'd wouldn't sound too special.

mp3 is a pretty poor compression any way. High enough bitrate to sound good and butcher the sound, and the file sizes dfeat the purpose. That it has become the defacto standard for audio compression when there are some many better options around is pretty disappointing.

OK - so I am not a fan.

One of the things that really frustrates me is the way mp3 muddies the stereo seperation. I do a lot of audio processing for a local dancing school. A lot of the work is recutting tracks to seamlessly shrink to 2 minutes in length, or pitch shift or time stretch tracks. The other major work is vocal removal. The school has the appropriate licenses, so all of this is above board. Unfortunately, too many of the students are of the mp3 generation, so I get compressed tracks to work on. (I tell them not too, but it happens anyway). I have found many times that if I can get the CD original, I can get a pretty clean removal, but if I have to work from mp3 versions, it is almost impossible, as the compression causes artifacts and differences between the channels.

The main point of using DTS is it's impressive clarity, and fine seperation. As you will get neither of these from an mp3 source, you might as well use mpeg audio or 2 channel ac3.

Thank you for your replies so I just wanted to know few opinions
am aware that mp3 are not the best for compression but I just asked the question for the sake of experimenting

[lordsmurf]

Yes.
But I don't know what makes DTS.

Besweet may be part of the equation.

Yes and it is actually fairly ease, provided you have appropriate audio tools. Here is a 3-step way to do it:

1. Open your mp3 file in any sound-editing applacation (such as Sound Forge, WaveLab, etc.)
2. Copy the left channel of your file and paste it into a new mono file. Save it in .WAV format. Do the same for the right channel
3. Load your two mono files into Minnetonka's DTS encoder (not free), hit Encode, and you are done. You will end up with either DTS WAV or .DTS file, depending on the setting you choose.

In principle, any wave file can be turned into DTS this way. One of the posts in this thread is referring to Glossary which indicates that DTS is a multi-channel format. I think that the glossary entry should be corrected by way of indicating that DTS format can support up to 5.1 channels encoding and is not multichannel by default. Whether you get it as mono, stereo, quad, or whatever else depends on the number of channels you wish to have in your DTS file. So stereo DTS is a definite option.

The other issue mentioned here is, of course, the quality of your source material, which would have an impact on the quality of your DTS. MP3 is not really the best source there is to create DTS because you are dealing with multiple encoding/reencoding lossy compressions. Keep in mind that DTS is also a lossy compression format so whatever source you are using some of it will be lost in the conversion process.

DTS supports up to 10 channels actually
