I was trying to convert a .wav audio file to .dts audio file with eac3to but I can't and the program says:

The DTS Surcode encoder doesn't seem to be installed

Where can I find "Surcode DTS Encoder" or any other alternative and how should I install it?

Also, I cannot change the bitrate in any .dts file. For example, I have this:

DTS 2.0 960 Kbps 16 bit

And I want:

DTS 2.0 896 Kbps 16 bit (like the original DTS Core)

Any way to do this?

Where can I find "Surcode DTS Encoder"

You'll find it from an authorized retailer like in the following link:

https://www.bhphotovideo.com/c/product/439464-REG/Minnetonka_SDVW_SurCode_DVD_DTS.html

It's proprietary, commercial software.

For what you want this?

For a 2.0 audio is too much bitrate.

BTW try this:

ffdcaenc (http://forum.doom9.org/showthread.php?p=1688150#post1688150) -i input.wav -o output.dts -b 896

Because the original DTS Core has that unusual bitrate. I'm going to try with ffdcaenc as you all say (I've never used it) and I'll tell you the results.

tebasuna51 is correct. For 2.0 audio, even the DVD-Video specifications indicate a lower maximum bitrate,
namely 503.25 kbps (sampling rate = 48 kHz).

960 kbps is not unusual for Blu-Ray. But it should be unusual for 2.0 DTS.
Yes, not every «professional» user of the Master Audio Suite knows very-well what they do :D

Where should i place the “ffdcaenc.exe” file? I have placed it inside the "UsEac3to" folder and then I’ve done the following:

I run “UsEac3To.exe” and I fed it with the .dts file that I want to modify, “audio.dts”. I want to try this but I guess I have to change something:

ffdcaenc -i input.wav -o output.dts -b 896

But, what?. Something like that?:

ffdcaenc -i audio.dts -o output.dts -b 896

In both cases Useac3to says the same thing:

Command line parameter "i" is unknown. <ERROR>

I don't know what I need to change or maybe I need to install ffdcaenc in a different way.

If you use UsEac3to load the input and select Output format "dca-ext", then 'Add' and you obtain:

stdout.wav | ffdcaenc -i - -o %_2eng.dts -l -b 1509.75

Is the standard bitrate for 5.1, modify the bitrate to: -b 896

Maybe you want some other parameters, for instance change the duration from 25 to 23.976 fps, modify to:

stdout.wav -25 -changeTo23.976 | ffdcaenc -i - -o %_2eng.dts -l -b 896

As previously mentioned the 896 bit-rate that maldon is selecting is too high for 2-channel stereo encodes.

Especially when you consider that many of the newer movie DVD releases which offered 5.1 channel DTS audio, were encoded at 754.5 kbps!

@maldon,

Out of interest... Why do you want to generate 2-channel/stereo DTS encodes?

Dolby Digital (AC3) and Dolby Digital Plus (EAC3) works very well and is pretty easy to encode using UsEac3To (as a front-end).

Cheers

As previously mentioned the 896 bit-rate that maldon is selecting is too high for 2-channel stereo encodes.

Especially when you consider that many of the newer movie DVD releases which offered 5.1 channel DTS audio, were encoded at 754.5 kbps!

Because I wanted the DTS Core to be the same as the original:

DTS-HD Master Audio English 1196 kbps 2.0 / 48 kHz / 1196 kbps / 16-bit (DTS Core: 2.0 / 48 kHz / 896 kbps / 16-bit)

If you use UsEac3to load the input and select Output format "dca-ext", then 'Add' and you obtain:

stdout.wav | ffdcaenc -i - -o %_2eng.dts -l -b 1509.75

Is the standard bitrate for 5.1, modify the bitrate to: -b 896

Maybe you want some other parameters, for instance change the duration from 25 to 23.976 fps, modify to:

stdout.wav -25 -changeTo23.976 | ffdcaenc -i - -o %_2eng.dts -l -b 896

The result:

DTS, 2.0 channels, 1:28:10, 960kbps, 48kHz
The ArcSoft and Sonic decoders don't seem to work, will use libav instead.
Patching bitdepth to 24 bits...

Reducing depth from 64 to 24 bits...
Writing WAV...
Creating file "stdout.wav"...
Writing the destination file failed. <ERROR>
Aborted at file position 524288. <ERROR>

It seems that the DTS file I have has some problem, Medianfo says it has 16 bits, but for Useac3to it seems to be 64.

Patching bitdepth to 24 bits...

Reducing depth from 64 to 24 bits...

And also this. What happened?

The ArcSoft and Sonic decoders don't seem to work, will use libav instead.

I don't quite understand it, but maybe the bits are the reason for those errors. Well, it doesn't matter if it's hopeless. The point is to start with my first DTS conversions.

By the way, with ffdcaenc it is impossible to convert from wav to DTS-HD Master Audio?

It would seem that you are not aware that it's possible to extract the original lossy DTS core from a DTS-HD MA stream then?!

These messages are from a old eac3to version, than can't decode DTS-MA. Please use the last version (http://madshi.net/eac3to.zip) with libdcadec.dll

Of course, you can obtain only the DTS core, like you say at first post.
If you want obtain a DTS-MA you can't fix the bitrate.

There IS something weird in there...
896 kbps is not a valid (or exact) bitrate for 48 kHz DTS audio...
with a granularity of 4 bytes per audio frame, the bitrate must be an integer multiple of 3 kbps at 48 kHz :confused:

The result:

DTS, 2.0 channels, 1:28:10, 960kbps, 48kHz

Definitely an outdated version of eac3to. 960 kbps is the "transmission bitrate", a very-useless metadata field invented by DTS, Inc. themselves.
The latest version of eac3to is able to calculate the actual bitrate of the DTS "core" streams correctly.

ffdcaenc can obtain a granularity of 2 bytes.
Using -b 896 I obtain:
Number of PCM Sample Blocks .: 15 ( 512 samples/frame)
Primary Frame Byte Size .....: 1195 ( 1196 bytes/frame)
Audio Channel Arrangement ...: 2 (2 L + R stereo)
Core Audio Samp. Frequency ..: 13 (48 kHz)
Transmission Bit Rate .......: 16 (960 Kb/s)

with a real bitrate of:
1196*8*48/512 = 897 Kb/s

But using -b 895.5 I obtain:
Number of PCM Sample Blocks .: 15 ( 512 samples/frame)
Primary Frame Byte Size .....: 1193 ( 1194 bytes/frame)
Audio Channel Arrangement ...: 2 (2 L + R stereo)
Core Audio Samp. Frequency ..: 13 (48 kHz)
Transmission Bit Rate .......: 16 (960 Kb/s)

with a real bitrate of:
1194*8*48/512 = 895.5 Kb/s

And eac3to, and MediaInfo, round to:

DTS, 2.0 channels, 0:02:55, 896kbps, 48kHz

Of course don't have sense that bitrate for a 2.0

No, I'm trying to explain that the original DTS-HD MA has a DTS Core of 896. I just wanted to show that there are Blu-ray releases with that kind of bitrates, besides the common 768 and 1509. I don't have that DTS-HD MA just a DTS 960 that I want to reduce to the original 896.

These messages are from a old eac3to version, than can't decode DTS-MA. Please use the last version (http://madshi.net/eac3to.zip) with libdcadec.dll

It works with this:

https://www.videohelp.com/download/eac3to334-UsEac3to129.zip

And this:

stdout.wav | ffdcaenc -i - -o %_.dts -l -b 895.5

The result:

Before:

960 kb/s, 48 kHz, 16 bits, 2 channels, DTS

After:

896 kb/s, 48 kHz, 24 bits, 2 channels, DTS

So, If I want to keep 16 bits, ¿where I must place -dontpatchdts?. I tried this, but no results:

stdout.wav -dontpatchdts | ffdcaenc -i - -o %_2eng.dts -l -b 895.5

Of course, you can obtain only the DTS core, like you say at first post.
If you want obtain a DTS-MA you can't fix the bitrate.

Well, I took a new .mkv file (with .FLAC audio) and I convert .FLAC to .WAV with Useac3to. Now, I want to convert .WAV to DTS-HD MA but I don’t know how. The reason is that I would like to know if that DTS-HD MA I obtain from the .WAV file would have a DTS Core.

I can't understand for what you want recode a DTS to obtain exactly a bitrate. You want deceive somebody?

A lossy encode don't have bitdepth, the info 16/24 bits are wrong. Internally are 32 bits floats samples in frequency domain.

For that the free encoder, also the old commercial encoder Surcode, put always 24 bit in the header field refering to the source, because decode the internal 32 float to 16 int losse precission.

I only know other commercial encoder DTS-HD Master Audio Suite, but with that you can't select exactly the bitrate.

Now, I want to convert .WAV to DTS-HD MA but I don’t know how. The reason is that I would like to know if that DTS-HD MA I obtain from the .WAV file would have a DTS Core.

You need buy a commercial encoder:

The suggested retail price for the DTS-HD Master Audio Suite is $1,495

and like I say before can select the core from:

No, I’m not trying to deceive anyone because the original DTS Core from Blu-ray and mine are not the same. I mean, the audio track included on the Blu-ray is not the original Italian dubbing. My DTS file is the original dubbing and I was wondering if it would be possible to get a DTS file with that bitrate and keeping its 16 bits, since -dontpatchdts doesn't seem to work in this case.

But the most important thing is that both audios are not the same length. My DTS is 9 seconds longer and I want to cut it to fit the length of the video. So, I open the previous version of "UsEac3to" and then I click "DelayCut" to see the Info (it's my DTS file not yet converted to 896):

====== INPUT FILE INFO ========================

As we can see my file is 01:28:10.144 and must be 01:28:01.280

If I go to Cutting and select “Cut File” I can introduce numbers on Start (msec) and End (msec). Those numbers change the duration, but I don't know how to figure out which ones to include to get exactly the desired duration.

Good to know your problem, then:

- You can't replace the core of DTS-MA, you can add another track with your DTS, and delete or preserve the BD track.

- Like you can't replace the core is indiferent the bitrate and, of course, the bitdepth of your DTS. Try to preserve your DTS without recode lossing quality.

But the most important thing is that both audios are not the same length. My DTS is 9 seconds longer and I want to cut it to fit the length of the video.

This is other problem, sync your audio with the BD video.

I can say you how cut the DTS, but at the beggining, at end, in the midle?

Sometimes there are different credits at the beginning, or end, but you need compare the BD audio with your DTS to exactly cut the right parts.
Decode to wav with eac3to both DTS's and compare them with a audio editor like Audacity.
