Thanks. I was just using the algorithm in the specification, but I did some modifications, and now the stereo rematrixing works a little bit better. The changes have been committed to SVN.

Also, I have created a cron job which will upload daily builds. They can be accessed at:
http://jbr.homelinux.org/aften/daily/
the .zip files are win32 binaries
the .bz2 files are source files

The job is set to run every day at 4:50AM EST. I already made some builds for today (6th) and yesterday (5th) as a test. The ones for the 6th will be overwritten at 4:30.

1st post and GUI updated.

@Raquete : AftenGUI 1.1 doesn't work with aften 0.03-dev and higher due to the bitrate tweaking (bps --> kbps). It should be fine now with the 1.2.

I'm ok for #2 but this depends of your source. Regarding #1, this doesn't make sense, sorry. "Reencode an ac3 stream to have multichannel playback"...It's really funny imho. If it's not a pleasure for you, well don't reencode them. Don't waste your time with this, it's really precious for other things.

I am less familiar with the behappy wrapper than the original open avisynth environment.
So you can regard I am well aware of the avisynth's wide range capability of the bit sizes.
However, in the older(20060226) source of the AvisynthWrapper.cpp I read :
Code:
  if (inf.HasAudio()) 
  {
   *originalSampleType = inf.SampleType();
   if( *originalSampleType != SAMPLE_INT16) 
   {
    res = pstr->env->Invoke("ConvertAudioTo16bit", res);
    pstr->clp = res.AsClip();
    infh = pstr->clp->GetVideoInfo();
    if(infh.SampleType() != SAMPLE_INT16) 
    {
     strncpy(pstr->err,"Cannot convert audio to 16bit",ERRMSG_LEN-1);
     return 6;
    }
   }
  }
which forces any audio stream process beyond 16bit not that useful including aften ac3 encoder through pipe.
There might be some reasons for this restriction or already excluded(which I cannot confirm) that behappy users with aften certainly want?
(I am not sure if this issue is discussed already)

Thanks.
[edit] I confirm the latest cpp source dated 05/09/2006 is unchanged in the mentioned area.
That one was implemented by the orig author 'mobileHackerz' of avsredirect.dll on which avisynthwrapper does base on.
Its kinda forcing a compatibility as its original purpose was to serve avs frameservingdata to ffmpeg. Just alter that section or even mark it using "//", compile the dll using VSC++ Express 2005 and see what happens when using in Behappy etc.

Thanks, I am forwarding it to tebasuna. The reasons explained.
And thanks gents, I will check the daily builds whenever possible and demanding.

I invite anyone who is interested in the development side of Aften to join the aften-devel mailing list.

Actually, you have just to concentrate on the "General" Tab for *Normal* encodes. All others depend of your needs.

Version 0.05 released today.
Biggest improvement: 30-50% speed increase (depending on platform & CPU)

jruggle - do you have any plans to try and get some of these changes in to ffmpeg/libavcodec ? that would be nice.

i'm using short blocks. haven't done any ABX'ing yet, but some samples with crackle, castanets and heavy brass don't sound obviously bad.

Yes, the recent speed-ups can be ported back to ffmpeg. Also there are a couple bug fixes.

That sounds great, hopefully an organized listening test comparing Aften to commercial encoders will take place at HA soon.

Hi Guys,

Can someone make HTML Guide for Aften? I'd like to include it in my installer as a reference guide for Aften.
Also, @kurtnoise,
can you send me your GUI with 48x48 or higher res icon? Check your mail as well .

IMO, excellent AC3 encoder like Aften deserves a bit more attention, meaning,

avearge Joe will not understand short blocks, dialg norm,mid-side stereo...

We need full on guide with all of the settings explained.
From my tests so far I think Aften produces very good output .
