Ok, Just got off the phone with AlexG, many thanks for the conversation and time discussing DTS to High Res issue I was trying to solve!
It turns out to be relatively easy!
The surprise here is that it seems from the data I have looked at that you can get FLAC 24 bit depth file sampled at 44.100 Hz.
Here's is the short version:
Get Foobar 2000m the version I got was V1.1 and find (google search) the foo_input_dts_dll file.
Install foobar and then copy the dts dll to the components directory...this directory is a folder in the Foobar folder..where you installed Foobar.
Then get the FLAC convertor from:http://flac.sourceforge.net/download.html
Scroll down on this site for downloads and you will see a WINDOWS section. Select the FLAC with Windows installer.
Install this, remember where you put it. Later in Foobar you will have to point to the flac.exe file for the magic to happen.
Ok so you have Foobar installed, copied the dts dll file to the components directory and then installed the FLAC stuff.
I used a DTS 5.1 Music disk, Diana Krall, Love Scenes. Insert into your pc cd/dvd and open foobar.
Click on File, and Select Open Audio CD, a small window pops up showing you your CD drives found...I select Add to playlist and all the songs on the DTS disk should show up in the Foobar main menu. The first song probably will be playing. If you copied the dts dll correctly the song should be playing.
Stop the song playing (click on the player control for STOP), select the first song. Right click on it and a small menu pops up, select the three dots "..."
The convertor window pops up. This is where you can save presets for later conversions.
I select output format on the right top side then another window pops up where you actually can select the output file format from a list. I select FLAC. level 5 the FLAC default.
At the bottom of this output file format window there is an output bit depth its set to AUTO. I used this and played with the bit settings.
Auto here got me 24 bit FLAC files from the DTS music disk. I tried 32 bits for the heck of it, still got 24 bits in the file I converted.
Ok so once you select the output file format, and bit depth...select the back button at the bottom. Now you back at the Convertor setup window. You can select destination and Processing.
Under Processing I add the convert 5.1 to stereo DSP. On the processing window on the left are the Active DSP's on the right are the Available DSP's. Select this one and click on the arrow to add it to the Active DSP window. Then click on Back to get you bcak to the main Convertor setup window.
Then click on convert. A window pops asking you where to save the file etc. You will for the first time get a window asking you where your FLAC.EXE file is. Point to this file.
The convert 5.1 to stereo to 2 ch DSP I added seems to only output a file that has 2 ch (what I am intersted in). and the file size is a LOT smaller. If you dont select this you get ALL 6 DTS channels and the file size in my case was in excess of well over 100mb.
I would think your would be able to stream this to a player as well as the 2 ch flacs I made via UpnP DLNA etc..hmm something to further investigate.
Any how, I now have 24 bit files from the DTS 5.1 music disk, I know the file properties say only 44.1 Khz sampling rate, but its 24 bits.
Thanks much for AlexG helping me think thru this one!
All the best
