AC3Filter prerelease version (ac3/dts/lpcm support)

[neo75903]

@daphy:
I am aware of that, but users from this forum can provide real world usage tests. We can confirm what does and does not works with what configuration and amps for example.

[daphy]

whats about the new build, does it finally support DTSWAV? :rolleyes:

[MacAddict]

Finally got the email confirmation this morning and was confirmed. I have no idea where the download link is though:confused:

[jimwhite]

I can't login, it won't accept either my name or password!

log-in?
it's a ML

[sillKotscha]

ehrm, I guess valex would have posted this version here, too if he was willing to...

but as we could read above... he wants a closed test till now, so I think it's not a good idea to post hist testversion here...

right, this post, expecially the link should NOT be hre in public

I think it is broke anyway, I get a "missing MSVCRTD.dll" error when I try to run it.

EDIT:
It works you just need that dll installed to your Windows/system32 folder.

If you do not have that dll you can get it here:

[E-Male]

gaaaaaaaaaah

[MacAddict]

It's not broken at all, just a little reading of the digest tells you the quick fix to the dll.

I tried to get into the mailing list, I also got a confirmation mail, which needs to be answered by another mail. Everytime I try to send my mail to scourceforge i receive an error message from the mailer-daemon:

<ac3filter-testing-request@lists.sourceforge.net>:

Is someone familiar with this problem?

Thanks for your patience...

Don't panic guy's!

I've been testing the new builds (we are currently up to "Test3"), and things seem to be coming along very well ;)


Cheers

[neo75903]

Thnx SeeMoredigital I am looking forward for the next release. Actually the current release is working fine for me, only thing on my wish list is to upsample 44 to 48.

Some kind of wraper for it that would make it work with games would be awesome. It would just need something that would force any analog sound to be passed through the filter before going to the sound card.

[Tony Maroni]

@socio:
Yes that would really be awesome!!!
Then finally i could use my creative card in the way it was supposed to when i bought it...

I hope it will happen someday....

Yep, I should mention that this idea is not mine it actualy came from someone named taz291819.

[Tony Maroni]

Last week, the european pr-guy from creative was sitting in a german tv-show called GIGA-Help (cancelled now) and was promoting their new software Audigy 4(calling it new hardware is purely wrong!!). The audience was asked to post questions for the guy, and luckily mine was picked.
Of course i asked when will Creative produce a fully EAX supported card with a Dolby Digital Encoder(Like Soundstorm for PC or in the XBOX). The answer was very disappointing!!
At first he pointed the big hit on the CPU. Well for me that sounds like a poor one... Even XBOX games can handle this with 733 Mhz, and further, why not support it in hardware?? This can't be so hard...

Then he said the quality would be too bad for customers because of the compression!!
Well man, you can't be serious... Every DVD has compressed AC3 and for my ears, it sounds quite good!! And again the XBOX can be mentioned, bad quality with XBOX Dolby Digital because of compression??

So he said, we will never see such a card from Creative!!

So either you buy a motherboard with soundstorm(quite bizarre to buy a mobo for better sound...) or put all your hope in programmers like Valex and wait that someday a solution for gaming with ac3 encoding will appear!!

[Socio]

Yep,

A while back I read an interview with one of the Creative guys and he was asked about supporting DD encoding and said that their EAX was far superior to DD so supporting DD encoding would be a step backwards.

Needless to say if someone can figure out how to force all analog sound to pass through the AC3filter before going to the soundcard we would could have DD EAX gaming.:D

Not only that but if you have a PCTV card like a Dvico Fusion HDTV card all analog cable and OTA TV could be watched in DD surround.

It might be as simple as going to the registry and changing all supported audio outputs to default to the AC3Filter.

I want to make a request.

Can we have a 'seperate' option to send AAC 5.1 to SPDIF (AC3 transcoded)?

At present in order to get 5.1 AAC transcoded to AC3 5.1 and spat out the SPDIF you have to tick PCM option, which means any and all WAV, MP3 and Ogg gets sent to the AC3 transcoder as well! Very irritating. Of course if I untick PCM then AAC 5.1 does not get transcoded. I have to keep switching!

[E-Male]

i daubt valex reads this thread, as he has his mailinglist now

Very irritating. Of course if I untick PCM then AAC 5.1 does not get transcoded. I have to keep switching! I think it's a bit of a shame that AC3Filter does not have it's own AAC decoder, as this would make the whole AAC to AC3 transcoding situation much easier.

Just to keep you up to date, when I suggested this to him he replied: AAC decoder will be in far-far future... I even (very cheekily) suggested a revised GUI, so that AC3Filter would be prepared to cater for future audio stream innovations: -

http://img46.exs.cx/img46/1301/ac3filtersystem4yh.gif

I think it's fair to say that Valex's AC3Filter is certainly respected and there are loads of us that want to use it!

But in the meantime, for all those who need AAC to AC3 transcoding, maybe FFdshow's audio filters would suit you better. As discussed toward the bottom of this page: -

http://forum.doom9.org/showthread.php?s=&threadid=89284


Cheers

EDIT: Proposed AC3Filter GUI ammended... To protect the innocent!

[oddball]

I can't get it to work in ffdshow. The audio stutters and the video playback crawls.

Wait where did you getr this version of AC3Filter!? I must have it! Please?

[oddball]

Can we have the option to send only 5.1 AAC/Ogg etc to the AC3 to SPDIF output? At present if you tick AC3 it sends 'ALL' audio to it. This is not the ideal for me. Why add extra CPU use to audio streams that do not need it (I.E. converting to AC3 on the fly means CPU extra CPU usage)?

Ideally the option to send to AC3 should be on a dropdown on the codecs menu of ffdshow so you can select which codecs to send to AC3 and which type (I.E. option to set 2.0 as untouched and 5.1 as converted).

EDIT: OOPS! This was meant to go to the ffdshow thread not the AC3Filter thread. But I guess it's just as relevant.

[hippoth]

No more news for the AC3Filter? I subscribed to the mailinglist in the hope to get any news or a link to a version I can test...but nothing :(
How can we talk in the mailinlist about testing without an available version?

[E-Male]

the 3rd test verison is out for some time now
maybe you should write to the ML, introduce yourself (valex has written in the sourceforge forum what info he wants) and ask for the link

[MarkCoolio]

Just to inform u that a new version is out:

AC33Filter 1.02a Test4

You can find it under the link that valex gave out for the previous test versions.

Can't find it... can you post the link?

Uh-oh... hope Valex doesn't get pissed and leaves development again.

Why should Valex get pissed?

just found that post, so i removed the link - sorry

[sillKotscha]

but maybe the changes made by valex are interesting enuff to post 'em...

Changes in AC3 Filter 1.02a test4:

- Documentation was fully rewrited (much of information about how to setup and tune the filter)
- updated DRC algorithm (reduced noise)
- DRC bug fixed (sound disappeared sometimes)
- AC3 encoder bug fixed
- Added AC3 CRC check

Changes in AC3 Filter 1.01a RC5:

- First working alfa for new filter generation
- Totally rewrited
- 10%-20% less CPU usage
- Level meters are now syncronized with playback
- DTS decoding support (including AVI/DTS and WAV/DTS)
- MPEG1/2 Audio Layer I/II decoding support
- DVD/LPCM decoding support
- Audio processing for any kind of audio track
- AC3/DTS/MPEG Audio SPDIF passthrough
- Real-time AC3 encoding for multichannel SPDIF output
- More powerful dynamic range compression

Changes in AC3 Filter 0.70b:

! Serious bug in decoder fixed. Sound is _much_ better now especially on low bitrates.
* Some optimizations.
* Updated DPLII downmix matrix according to http://forum.doom9.org/showthread.php?s=&threadid=57988 (thanks to bleo!)


• Important Note:
- There is a bug in the AC3 Filter 0.70b (and perhaps later versions) that prevents it from working well with Media Files that contain multiple AC3 Audio Tracks. Installing AC3 Filter 0.7b FIX will solve the problem (this fix doesn't contain all files, install standard version first!)

sorry, but where do I find this fix :confused:

[pieroxy]

Maybe you would find the answer in reading the thread? Hmmm? :rolleyes:

Valex did set up a mailing list for those that wish to beta-test ac3filter. You just need to get on it and wait for the next release.

The address of valex's post onto the sourceforge forum is in an older post of this thread.

[bourtzovlakas]

sorry, but where do I find this fix

<link removed until the GPL question is resolved>

[Doom9]

this raises an interesting GPL question, unless the dts code has been completely replaced.

I figure the reason for having a private test is the GPL is just that binaries can be distributed without corresponding source (for the backstory, that's available earlier in this thread).

You can privately distribute binary-only derivations of a GPL'ed work, as long as it stays in a closed group. If one member breaks outside that group and makes the binary available to the general public (as in putting up on a public website for everybody to see), we have a license problem on our hands. The distributor is supposed to offer access to the sources and if this cannot be done, distribution is in violation of the GPL.

[magicclue]

so you want to tell that this site offering the new AC3 Filter version is raising an issue on violating GPL?
Maybe only a few let's pretend a closed user group surfing by are able to take part in the downloading :-)

<link once again removed until the GPL compliance can be assured, next time it's a strike for violation of a moderator order>

What's all the hype about it?

Apparently a few people here aren't understanding the idea behind a closed group beta test. Stop posting the test links and join the SF group as mentioned at the start of the thread people!

I only posted the link for the AC3 Filter 0.7b FIX....
No closed group beta test version....
Maybe you should read more carefully, before posting judgements and accusations...

How can i read carefully a removed link?????
You are not making any sense...

[KpeX]

I'm going to close this thread, since this discussion is neither useful nor on-topic. Doom9's statement stands, we won't be discussing any links to private tests here, since unless the source is released, any public test versions are still in violation of the GPL.
