anyone compiled and tried dcaenc ?

[LoRd_MuldeR]

Do I get this right? You try to pipe a 'w64' file into dcaenc? I don't think its Wave parser will be able to deal with that. It was written with plain RIFF/Wave files in mind and nothing else.

(The only thing that the "-l" option does is ignoring the length field of the "data" chunk, as that field may not contain a valid value, e.g. in case of reading from STDIN)

Well the command line I posted was attempting to have sox convert the w64 to wav and then pipe that into dcaenc and thereby hopefully get around the 4GB limit of doing two separate steps by first converting to wav. So dcaenc is reading from the STDIN.

It seemed like it worked except for the fact that sox has issues in general with w64. The resulting DTS was the same length as what sox thinks the w64 is.
[code]

Actual length 3:13. This is a known problem with sox and w64 that is currently being worked on.

Thoughts? Recommendations for getting this huge w64 file to dts?

I know this is getting slightly off topic, but it is very relevant to dcaenc because many audio tracks will exceed the wav size limit.

Recommendations for getting this huge w64 file to dts?

If you're looking for a "one-line" solution, I'm afraid you won't find it anytime soon. So if I were you, I'd split that .W64 file into several mono .WAVs through eac3to, and then write an appropriate audio-only && multichannel Avisynth script, so that

.AVS -> wavi.exe -> dcaenc.exe

Hope this helps :o

P.S.: LAV Splitter supports the W64 container, thus maybe you don't need eac3to in this case ^.^ ;

[b66pak]

or you can pipe using eac3to....

Lord Mulder apparently thought I had used a "git clone" of Patrakov's original code. Actually, I had used the tarball available on Patrakov's web site; that tarball was!/¿still is? "ready for configure" :cool:

Besides, Lord Mulder did appear to ignore that his own gitorious folder is able to generate a tarball for the people who don't want to use the git application --- however in this case, the content of the tarball is not different from the git clone :helpful:

I see. As long as SoX sends a valid Wave header (with valid "fmt" and "data" chunk) over the pipe this should work. You'll have to use the '-l' switch for dcaenc, of course.

Very well... That's the reason why I have added this text to main.c:

besides, ( regarding the "bitrate hell" :p ):

The *actual* bitrate can be any value between 32 and 6144, BUT
the minimum and maximum values vary according to the frequency and the channel-layout;

I also modified the error message about "insufficient bitrate", because
5400kbps cannot be "insufficient" for a mono input @ 44.1kHz ;)

[LoRd_MuldeR]

Here is a new build that allows the user to overwrite the pre-selected channel configuration (see help for details). Updated DLL is included.

[Selur]

Nice,thanks !

[LoRd_MuldeR]

Build in previous post updated: Channel configuration will now be checked for compatibility with input Wave file. Also added switch to indicate presence of LFE channel.

If, for example, you want to create a typical "5.1" encode from a six channel Wave file, then use 3FRONT_2REAR ("-c 10") in conjunction with "-f" switch - this is the default for 6ch input.

You could even create a "Center-only with LFE" encode now from a two channel Wave file by using MONO ("-c 1") in conjunction with the "-f" switch, confirmed by MediaInfo.

Added option to overwrite auto-selected channel mode. Also improved the help-screen (thanks to 'Selur' for testing all the bitrate/channel/samplerate combinations)

1) Certainly Selur's job is much better than mine :o , no doubt about this, however his list is far from complete :( The frequencies 11.025kHz and 24kHz are missing, not to mention the channel-layouts with 3 and 4 channels ;)

regarding 3 channel: -> "Error: Unsupported number of channels (only 1, 2, 4, 5 and 6)"

Yes, it's not supported.

If it turns out that this is only a limitation of the Wave reader, I can fix it (easily).

But if it's a limitation of the actual encoder, I probably can't do anything...

[amtm]

Has anyone compared the surcode DTS codec to dcaenc to see what the actual differences are? Aside from Surcode costing $250 of course. :) Just curious...

The major differences would be that it supports all the extended DTS formats (DTS-ES, DTS-HD HR, DTS-HD MA, the 96/24 extensions, etc.) and additional channel mappings that dcaenc doesn't. In my tests it's also more optimized and probably has more advanced psychoacoustic enhancements in it as well. It's also unusable for making silence frames for extracted DTS-HD cores since the frame size of dcaenc output matches that of DVD DTS and so outside of libavcodec your DTS track won't decode (this is why dcaenc can't be used to fix delaycut's issues with Blu-Ray DTS tracks).

Please forget what I said about the 2.1 .DTSs --- there was some kind of conflict between LAV Audio and the Audigy drivers :confused: but now that's all solved ( or at least it seems so :o ). I checked with foobar2000, and the 2.1 DTS appeared to be correct since the very beginning :o

BUT :devil: --- regarding the 3.1 DTS streams, the Front-Right and the Front-Center channels are swapped by dcaenc

:confused: :confused: :confused:

[LoRd_MuldeR]

It's probably because the Wave reader currently knows nothing about the channel configuration ;)

The ultimate solution will be to forward the selected channel configuration into the Wave reader too (not only into the encoder lib), so channel re-ordering can be done correctly.

Actually the Wave reader does some re-ordering already, but that was probably written with the default channel configuration in mind.

And even if we do it correctly, we still need to trust on the Wave file to have the channels ordered properly according to the Wave specifications for multi-channel files...

[Midzuki]

Thanks for the explanation.

Now, a pseudo-random thought:

IF Patrakov happens to read the post above, hopefully he will understand that the commercial multichannel encoders accept multiple MONO inputs because of a very-good reason :rolleyes: :p

[b66pak]

you can use sox to pipe mono files:

sox -M FL.wav FR.wav FC.wav LFE.wav SL.wav SR.wav -t wavpcm - | dcaenc -i - -o 5.1.dts -b 1509 -l
_

[Midzuki]

^ Have you tried to create a 3.1 DTS in this way?

I have always fed dcaenc with proper multichannel .WAVs, in this particular case I doubt the intermediation by sox can make any difference...

[b66pak]

use this:

sox 3.1.wav -t wavpcm - remix 3 1 2 4 | dcaenc -i - -o 3.1.dts -b 1509 -l -c 6 -f
_

L.E.

you can also force it to 5.1 (SL & SR will be empty)

sox 3.1.wav -t wavpcm - remix 1 2 3 4 0 0 | dcaenc -i - -o 5.1.dts -b 1509 -l

Nice. This might be an alternative solution for me, though I still haven't decided between dcaenc and surcode. I will have to do a test output from both to compare. One nice thing about surcode is that it will take a 24 bit input.

[LoRd_MuldeR]

With SoX, you can simply add "-b 16" or "-b 32" to do the required conversion.

[tebasuna51]

I think dcaenc must read the channels mask present in WAVE_FORMAT_EXTENSIBLE header to select/reject the channel configurations supported.

Is easy, first a new wavfile.h with:
typedef struct {
FILE * file;
unsigned int channels;
unsigned int bits_per_sample;
unsigned int sample_rate;
unsigned int samples_left;
unsigned int channel_mask;
} wavfile;

And in wavfile.c add:
/* wFormatTag */
result->channel_mask = 0; // unknow, then apply defaults s/channels

v = (uint32_t)fmt[0] | ((uint32_t)fmt[1] << 8);
if (v == 0xfffe)
{
result->channel_mask = (uint32_t)fmt[20] | ((uint32_t)fmt[21] << 8)
| ((uint32_t)fmt[22] << 16) | ((uint32_t)fmt[23] << 24);
v = (uint32_t)fmt[24] | ((uint32_t)fmt[25] << 8);
}

if (v != 1)
{
*error_msg = g_error_msg[6];
goto err3;
}

/* wChannels */

We can add also support for W64/RF64 files but now:
unsigned int samples_left;
must be unsigned int 64 bits;

I can suggest the code if you want.

If I were you, I'd use dcaenc for doing only what the commercial encoders cannot do. It's nice to know that now we have 9 sample rates to choose from, and I myself wasn't aware that the *actual* bitrates could be VERY different from the "official" bitrates. :stupid:

[tebasuna51]

And just as a reminder :)...

With less than 7 channels the:

SPEAKER_SIDE_LEFT 512 0x200
SPEAKER_SIDE_RIGHT 1024 0x400

can be used like BACK channels.

For instance eac3to output 1551 (0x60F) like channel-mask for 5.1 using SIDE speakers, but Faad, and others, output 63 (0x3F) for 5.1 using BACK speakers.

Now M$ prefer 0x60F for 5.1, but accept also 0x3F.

[Midzuki]

...
For instance eac3to output 1551 (0x60F) like channel-mask for 5.1 using SIDE speakers,

Hummm, now I understand why MediaInfo reports the Back-Center as a "side-channel".

I think dcaenc must read the channels mask present in WAVE_FORMAT_EXTENSIBLE header to select/reject the channel configurations supported.

While it would be good to support this feature, we cannot rely on it. Not all multi-channle Wave files have a WAVE_FORMAT_EXTENSIBLE header...

[amtm]

Nice. This might be an alternative solution for me, though I still haven't decided between dcaenc and surcode. I will have to do a test output from both to compare. One nice thing about surcode is that it will take a 24 bit input.

If you only care about encoding DTS for DVD then dcaenc should be perfectly fine for you. The benefits of a Surcode or the DTS Master Audio Suite is the fact that they do all the extra things I listed on the page back. Plus their GUIs are nice with built-in support for mono wav files and no need to dick around with SoX to pipe in input. It's up to you if $250 for Surcode, plus $250 if you want the Surcode for DTS-HD plugin for extended format encoding, is worth it. The only thing that Surcode is limited to with that plugin is that it can only do 6.1 encoding due to a limitation of Apple Compressor in Final Cut. On the other hand, DTS Master Audio Suite does the full gamut up to 7.1 but it's $1500.

[geminigod]

What I have is the surcode DTS DVD encoder. In test comparisons thus far with dcaenc I am not convinced that there is any psychoacoustic differences I can detect that this surcode encoder has over dcaenc. Both encoders were fed 6 mono wav files @ 48kHz. An old receiver of mine recognized both files as DTS and decoded them just fine.

The fact that dcaenc doesn't support 24 bit input really doesn't matter since it does support 32 bit. Thus it becomes just a simple matter of upscaling the bitrate in sox before piping to dcaenc.

One argument in favor of dcaenc is a rather strange anomaly that occurred with surecode. My dcaenc dts file and ac3 file are an identical duration of 3:13:49:088 (558,196,224 samples). The surecode dts file is 3:13:49:077 (558,195,712 samples). It isn't enough of a difference for it to matter to a viewer, but I am mildly curious why surecode's length is slightly off. Any thoughts on this discrepancy?

FYI for those like me who need to work with large audio files that exceed the 4GB limit, the command line I used is as follows (ignore the bit depth conversion part unless your bit depth of the input wav files is 24 bit:
sox -M "left.wav" "right.wav" "center.wav" "LFE.wav" "left surround.wav" "right surround.wav" -t wavpcm -b 32 - | dcaenc -i - -o "output.dts" -b 1509 -l

Sox effects could also probably be thrown into the same command line, but I did all of that earlier before I rendered my mono waves.
