If you're looking for FFdcaenc and not for dcaenc, then just go directly to this post

============== ORIGINAL MESSAGE BELOW ===============

Okay, here goes an up-to-date MinGW compile of dcaenc-2, based on the Windows-optimized code by Lord_Mulder. I have modified only the files main.c, wavfile.c and configure.ac, because the original stuff was cosmetically "UNacceptable".

Yes, its' working OK with foobar2000 and wine.

Time for a new build --- compiled with GCC 4.8.1, featuring a new icon

(shamelessly borrowed from MPC-HC ^.^; ), and more importantly,

additional and useful info on the help screen:

<snip>

DETAILS:

The input .WAV file must be either 16-bit or 32-bit integer;
the input or output file name can be "-" for stdin/stdout.

The bitrate is specified in kilobits per second and may be rounded up;
floating-point values are allowed.
Because dcaenc uses a 4-byte granularity, i.e., 32 bits per audio frame
(with 512 samples/frame), the ACTUAL bitrate will always be a multiple of:

3         kbps for     48 kHz
2.75625   kbps for   44.1 kHz
2         kbps for     32 kHz
1.5       kbps for     24 kHz
1.378125  kbps for  22.05 kHz
1         kbps for     16 kHz
0.75      kbps for     12 kHz
0.6890625 kbps for 11.025 kHz
0.5       kbps for      8 kHz

Thanks. I don't know if I'll ever use it, but it's nice to have just in case.

[racer-x]

I tried it out and it worked great. I muxed the streams into both an mkv and ts. I was quite surprised that my TV's media player (via USB) could play them......

Nice!

[El Heggunte]

Glad to hear that ^_^

But don't forget, the authors are Alexander Patrakov (first) and Lord_Mulder (secondly),
I am just a messenger =^.^=

[racer-x]

True, but I can't compile my way out of a paper bag. So I rely on smarter people like you to do the the dirty work (compiling programs) so that I can use them.

One of these days I'll have to learn to compile my own programs, but for now I'll let someone else do it.

[El Heggunte]

Today we present ffdcaenc 2.1.3 for your pleasure

ffdcaenc (Free Fast DTS Encoder) is a fork from mulders-dtsenc. It adds
support for 24-bit input files, multiple mono input files, flags for options
needed for DTS CD and DVD, and changes the core dcaenc library to support
DVD bitrates as expected by AudioMuxer and Muxman.

And more importantly, now it can be compiled on Linux too

[poisondeathray]

Maybe you can update title of thread to dcaenc 2 + ffdcaenc ?

[El Heggunte]

^ Title has been updated, thanks for the suggestion

[racer-x]

I'm not up to speed on this topic. So is ffdcaenc an improvement over dcaenc?

[El Heggunte]

I'm not up to speed on this topic. So is ffdcaenc an improvement over dcaenc?

Exactly. A russian guy named Alexei Andropov added significant and non-trivial improvements to dcaenc,
namely, support for 24-bit WAV files, one mono WAV file per channel, DVD-compliant bitrates (754.5 and 1509.75).

[cybero75]

hi, is there a option to switch L and R channel? And if yes, can u type command for it? I need ths urgently, thank you!

[El Heggunte]

Do you mean, switch the channels in a .dts file?

If your answer is "yes", then my reply is "no", because ffdcaenc is not a stream editor.

Otherwise, you can use eac3to for getting two mono inputs:

eac3to source.wav intermed.wavS

and then feed ffdcaenc with the correct mono inputs.

[cybero75]

thank you for reply ElHeggunte, i have a 32bit wav from VHS and im converting it to DTS 768, everything is great, ffdcaenc is great little bastard, but i found out that L and R channels in wav are accidentaly swapped (mapped). I switched them already in Izotope RX but i would like to know if is there a switch like ex. -c 3 R, L

[El Heggunte]

The dcaenc library has a serious limitation regarding the input's channel order and the output's channel layouts,
the -c switch was introduced by Lord_Mulder merely as a workaround...

You could use sox for swapping the left and right channels and then call "stdout",
if you think the extra step required by eac3to is "unacceptable"

[Surlias]

How do SurCode and ffdcaenc compare? Is either one any better than the other?

[poisondeathray]

It definitely won't integrate with eac3to directly like surcode dts (ie. you can't use a switch), unless madshi patches eac3to to do so

But it should be possible to pipe it with programs like ffmpeg


Q. common distributed ffmpeg binaries have "dts" for encoding now, does it use dcaenc or ffdcaenc ?

I'm interested in seeing comparison tests also

[El Heggunte]

Surcode is very-limited, its targets are DVD-Video and DTS-CD only.

DVD-Video supports only four bitrate values (754.5 and 1509.75 kbps for 5.1, 503.25 and 377.25 kbps for 2.0).

DTS-CD means 1234.8kbps @ 44.1kHz.

IMHO, one should compare ffdcaenc to the Master Audio Suite, not to Surcode.
Also, for ABX tests, using stereo sources is easier and more reliable than using multichannel sources.

[Surlias]

But as far as encoding DTS at the standard Core bitrate of 1536 Kbps, does SurCode produce results on par with ffdcaenc and Master Audio Suite? That's pretty much all I want to do with DTS encoding for now, convert TrueHD and uncompressed PCM Blu-ray audio tracks to DTS 1536.

[El Heggunte]

That's a different story, then.

At 1536kbps, you should perceive NO differences between ffdcaenc and the commercial encoders.

NOTICE: i.i.r.c., Surcode cannot give you ACTUAL 1536kbps,
it will only output 1509.75kbps "padded with zeroes",
if you choose the .dts file extension instead of the .cpt one.

OTOH, ffdcaenc does not have such limitation, since it is a fully-featured DTS "Coherent Acoustics" encoder.

As for the M.A.S., you shouldn't worry about it, unless your goal is create Blu-Ray~compliant files
(or do some ABXing ).

[El Heggunte]

Post #9 has been updated with a new binary.

Reason: there was a design flaw which broke the stdin support in the Windows builds =^.^=
