anyone compiled and tried dcaenc ?

[Selur]

btw. the MSVC project gives me:

1>c1 : fatal error C1083: Cannot open source file: '..\math_tables.c': No such file or directory
1>..\main.c(23): fatal error C1083: Cannot open include file: 'config.h': No such file or directory

[Midzuki]

Not-So-Humble Suggestion: while neither Patrakov not amtm manage to improve the encoder itself, the file main.c should include the following "mandatory"...

WARNING:
Currently not all possible combinations of frequencies and bitrates are supported.

Sure you have the solution/project file in the "vc_solution" sub-folder, as I have checked in the stuff?

If you put the project file into the "root" folder (i.e. where all the .c and .h files are located), you'll have to remove the "..\" from all paths (in the .vcprojx file)

[Selur]

here's what I did
1. I checked out git://gitorious.org/~mulder/dtsenc/mulders-dtsenc.git to G:\workspace\dtsenc
2. went to the vc_solution subfolder and double clicked the vcproj file for MSVC to start up and import the content
3. changed 'Debug' to 'Release' and started the build process
4. ended up with the error message

moving the lsn and vcxproj file and editing it (removing the ../) just changed the error a bit:

1>  dcaenc.c
1>  main.c
1>  math_tables.c
1>  unicode_support.c
1>c1 : fatal error C1083: Cannot open source file: 'math_tables.c': No such file or directory
1>  wavfile.c
1>main.c(23): fatal error C1083: Cannot open include file: 'config.h': No such file or directory

It seems "math_tables.c" and "config.h" are indeed missing from the repository.

The strange thing is, they don't even exist in the original repository. Well, the config file was probably created by the configure script.

Anyway, I will commit the missing files as soon as I return home...

It seems "math_tables.c" and "config.h" are indeed missing from the repository.

As you know, config.h is usually generated by a configure script, and that's the main purpose of configure.
math_tables.c is automatically generated while making.
(At first, a program named gentables is compiled from gentables.c, and math_tables.c is generated by running it).

This means that you must to be able to run the target binary (gentables) while making.
This can be a problem when you do cross compilation.

Should be fixed now

Thanks! Works here now!

@LoRd_MuldeR the MSVC builds are slow...can you also add a build with the previous method (MSYS+MinGW?)...

I posted MinGW/GCC builds earlier. Anyway, with MSVC+ICL the speed is approximately the same as with GCC - build attached.

Also tried to make x64 builds, but output is broken! I have no idea why that is yet...

[b66pak]

thanks a lot...

P.S.: That's not good-enough yet One must clearly state,
"this is an experimental DCA compressor" or something -.-

P.P.S.: Last but not least,

"original code by Patrakov",

"major improvements by Lord_Mulder",

whatever.

[Selur]

What's the meaning/effect of 'open' and 'VBR' for bitrates?

Currently not all possible combinations of frequencies and bitrates are supported.

if anyone has a list please share
48kHz 2 Channel works with: 320 384 448 512 576 640 (I would recommend 576 since at least my receiver doesn't like 640 )
48kHz 5.1 Channel works with: 755 1280 1509 3072 (I would recommend 1510 since 3072 seems like overkill )

Variable and loss-less modes imply that the data rate changes from frame to frame.

if anyone has a list please share

That's a W.I.P. , please be patient

Just my useless thoughts:

Many people think/say 5.1 DTS @ 44.1kHz @ 1234.8kbps is [ place your favorite superlative here ]. However, that's mathemagically-equivalent to 1344kbps @ 48kHz. In other words, 1509kbps has been overkill since the very-beginning

And considering movie soundtracks ARE N0T Audio-CDs ,
probably in most cases 1280, 1152, 1024, or even 960, kbps would have been more-than-adequate for them.

[Selur]

Since my Hardware decoder only supports 576kBit/s for stereo, I'll stick to the standard 1510 to be save.

[Midzuki]

Hummm, maybe you should SUE the manufacturer of your audio receiver --- they surely didN'T warn you that you were buying crippled firmware.

As for DTS, Inc. ...

you just give them some tons of money,
and they give you the right to use their logo

[Midzuki]

@ Selur: you've been using only the modded build, right?

Or not?

Because I have just tested the "unpatched" dcaenc on two short 5.1 .WAVs (at both 44.1kHz and 48kHz), and there were NO errors for all the valid bitrates between 754.5kbps and 1509kbps. And all the resulting samples played correctly with foobar2000.

[Selur]

I tried both, but I never said that there's a problem with 5.1wav -> dts withc 41./48kHz and bitrates between 754.5kbps and 1509kbps,..
I stated:
1. 48kHz 5.1 Channel works with: 755 1280 1509 3072
2. 48kHz 2 Channel works with: 320 384 448 512 576 640
3. 48kHz 2 Channel with 3072 does not work (freezes)
4. I would recommend 576 since at least my receiver doesn't like 640 dts for 2.0
5. I would recommend to use 1509 for 5.1 dts

Than you insinuated that 1509 might be overkill and I replied that I stick with 1509 due to the fact that my receiver is picky.
(and it's probably not the only hardware receiver that only accepts specific bit rates; mine also does accept all the bit rates (755+) for 5.1 audio, but since it's picky with 2.0 material I will stay with the common 1509kBit/s for 5.1 audio)

for me with 48kHz
for 5.1 only 755, 1280, 1510 and 3072 worked
for 2.0 only 320, 384, 448, 512, 576, 640, 755, 1280 and 1510 worked
worked = did not cause a freeze, crash and were really created
