Okay, with all the work being done with DTS audio I thought this basic "how to" I discovered seems to give a nice step by step way to accomplish the conversion on a very basic level.

There is software that it recommends but I'm sure there are other ones which may supplement what you need just fine.

Thanks to whomever wrote it as I forgot to mention it when I copied and pasted this.

With these steps you can convert your stereo audio to 5.1 channel(DTS) audio


The following softwares you need:
Goldwave (For producing individual channels)
Surcode DTS CD


First step is to select the audio file which you want to convert and name it something like source. [ Remember it should be in wave(.wav) format and its sample rate should be 48.0 KHz ]
Open your file with Goldwave.
In the toolbar go to Edit -----Channel-----Left. ( Now the left channel is highlighted )


Go to File-----Save selection as and save it as "Left front".
Note: select the format as "wave (.wav)" and "PCM signed 16bit mono" in attributes.


In the toolbar go to Edit -----Channel-----Right. ( Right channel is highlighted )


Go to File-----Save selection as and save it as "Right front".
Note: select the format as "wave (.wav)" and "PCM signed 16bit mono" in attributes.


While the right-channel waveform is still highlighted go to Effects-----Invert.


Go to Edit----Channel----Both.


Click File-----Save Selection as and name the file "Right back".
Note: select the format as "wave (.wav)" and "PCM signed 16bit mono" in attributes.


Close the file onscreen by clicking "File" and "Close" on the Goldwave toolbar. When prompted to Save file, select no. (This is so you don’t overwrite your original source file)


Open the original WAV named "Source"
Go to Edit -----Channel-----Left. ( Left channel is highlighted ).


While the left-channel waveform is still highlighted go to Effects-----Invert.


Go to Edit----Channel----Both.


Click File-----Save Selection as and name the file "Left back".


Close the file onscreen by clicking "File" and "Close" on the Goldwave toolbar. When prompted to Save file, select no.
Open the original WAV named "Source" and move your mouse over Goldwave's toolbar icons until you find the "Low/Highpass" option and click it.


In the "Settings", click the radio button which says "Dynamic". The default option is for the filter is "Lowpass" but if this isn't already selected, make sure that it is.
Change the "Initial Cutoff" to 80 and the "Final Cutoff"to 120 (you can just overtype the values). The default "Steepness" is 5, which is fine. Click "OK".


Click File-----Save Selection as and name the file "lfe".
Note: select the format as "wave (.wav)" and "PCM signed 16bit mono" in attributes.
This will be your subwoofer file.


Close the file onscreen by clicking File-----Close on the Goldwave toolbar. When prompted to Save file, select no.
Open the original WAV named "Source".
Move your mouse over Goldwave's toolbar icons until you find the "Maximise Volume" option and click it;


In the "Maximum (dB)" adjust the slider to 0.5, or just type the value in and then click "OK".


Move your mouse over Goldwave's toolbar icons until you find the "Parametric EQ" option and click it.


Choose the "Presets" option named "Treble boost" (its towards the bottom of the screen) and click "OK".


Click File-----Save Selection as and name the file "Center".
Note: select the format as "wave (.wav)" and "PCM signed 16bit mono" in attributes.


You now have six (5 + 1) channels from an originally stereo source
Instal Surcode DTS CD and open your six ".wav" files with that and setup the output destination and click encode.

Thanks for the guide!

I tried it out and it works well.  One thing I did that improved the overall sound was to use Effect -> Stereo -> Stereo Center to create the center channel instead of changing the maximum dB and EQ.  Also, for the rear channels, I used Effect-> Stereo -> Reduce Vocals along with the invert.

I'm glad it help you out.  With all the folks we have here I know audio is a big deal.  I figured this would come in handy.

I decided to write out the process I'm using, partially so I don't forget and partially to share.  Here's what I've been doing:

 

------------------------------------------------------------------------------------------

 

Convert stereo audio to 5.1 DTS surround


Programs Needed:
Goldwave
Surcode DTS Encoder

Part 1 - Goldwave

Open the audio file in Goldwave.  The sample rate needs to be either 44.1 khz or 48 khz.  If it not already one of these formats, click on "Effect -> Resample",

choose 44.1 or 48 khz depending on the current sample rate, and click "OK" to resample the audio.

Click on "File -> Save As...," at the bottom of the window set the "Save as type" option as "Wave" and the "Attributes" option as "PCM signed 16 bit, stereo."  Select

a location, name the file "source.wav" or something similar and click the "Save" button.

Click on "Edit -> Channel" and select "Left." Click on "File -> Save Selection As...," verify the "Attributes" option is set to "PCM signed 16 bit, mono," and save

the file as "Left Front.wav" or something similar.

Click on "Edit -> Channel" and select "Right." Click on "File -> Save Selection As...," verify the "Attributes" option is set to "PCM signed 16 bit, mono," and save

the file as "Right Front.wav" or something similar.

Click on "Edit -> Channel" and select "Both."  Click on "Effect -> Stereo -> Reduce Vocals," use the default settings, and click "OK" to process the file then click

on "Effects -> Invert".

Click on "Edit -> Channel" and select "Left." Click on "File -> Save Selection As...," verify the "Attributes" option is set to "PCM signed 16 bit, mono," and save

the file as "Left Surround.wav" or something similar.

Click on "Edit -> Channel" and select "Right." Click on "File -> Save Selection As...," verify the "Attributes" option is set to "PCM signed 16 bit, mono," and save

the file as "Right Surround.wav" or something similar.

Close the file and, when asked if you want to save, click "No."  Reopen the "source.wav" file and click on "Effect -> Filter -> Low/Highpass."  Under the "Settings"

section, click the radio button next to "Dynamic" on the right-hand side. Now change the settings to the following:

Under Cutoff Frequency:
Initial Cutoff = 80
Final Cutoff = 120

Under Settings:
"Lowpass" selected
"Dynamic" selected
Steepness = 5

Click "OK" to process the audio, click on "File -> Save As...," set the "Attributes" option to "PCM signed 16 bit, mono," and save the file as "LFE.wav" or something

similar.

Close the file and reopen the "source.wav" file. Click on "Effect -> Stereo -> Stereo Center," use the default settings, and click "OK" to process the file. Click on

"File -> Save As...," set the "Attributes" option to "PCM signed 16 bit, mono," and save the file as "Center.wav" or something similar.

Now you should have 6 seperate .wav files.


Part 2 - Surcode DTS Encoder

In Surcode DTS Encoder, click on "Setup -> New" to clear out any previous settings.

Click on "Options -> Encoder Options...," Set the "Sample Rate" option to match the sample rate of your source files, put a check in the box next to "Attenuate Rear

Channels 3dB" and click "OK."  The "Attenuate Rear Channels 3dB" works well on music and most audio but if you notice that the surround channels sound too quiet you

can leave the box unchecked.

Click on the buttons for the front, center, LFE, and rear channels and load the corresponding .wav files.  Click on the "Destination" button and set a location and

filename for the new file. For best results, save the file as either a DTS Wave file or padded DTS file.

Click the "Encode" button to encode the audio after verifying that the "Start" option is set to 00:00:00.00 and the "End" option is set to the end of the audio.
