  1. this does look promising, i just hope it catches on......i havent honestly given it a run yet, but to be able to perserve 5.1 at that type of bitrate does sound pretty cool....especially on movies with multiple audio tracks and such....

    Intresting.

    I think I'll give this codec a try.

    Keep up the good work.

  3. just curious, is it possible to make something thats backwords compatable to stereo with the same quality of the supurb quality setting? maybe up the bitrate if you have to? I'm just curious why the highest quality only plays back with mono audio if it doesnt have DLP II or the aud-x codec....

    Also, im just now giving it a stab, i noticed that its DRAGGING down my encoding times horrendously (im just doing a video stream copy and recompressing the audio) i'm not really complaining because i know generally, most things are kinda buggy/slow on their first release, but is there any chance of more optimization on this? I generally pull somewhere around 400-600FPS in virtualdub on a direct video stream copy and right now im getting somewhere around 30-40fps (this is only one audio stream, btw) maybe you should look into possible MMX optimization or something like that?

    3dsnar,

    I cant seem to get the Aud-X (VirtualdubMod version) loaded. I keep getting an error message about not finding or *.dll not found. Can I get a compiled, self-extracting *.exe version so dummies like me can use it? Thanks.

  5. ive got a few small bugs to report here....first off, i took the superbit version of the movie swat, and attempted to convert it using the guide you have...and the thing completely livelocked on me, i let it sit for like 4 hours, and it was stuck at 12% also another side note, i took a file that had some external audio tracks (in this case, it was 3 audio tracks in ac3 format) and it opened up 3 instances of the aud-x decoder.....obviously this drained my processing power up for a good minute or two before i killed it manually....may be worth looking into these issues (especially the multiple instances of the decoder opening.....i hate killing processes manually)

    Did you download our release of VDM? (available from www.aud-x.com)
    If you have it, please run the VirtualDubMod_Aud-Xenabled.exe
    And it should work. In case of problems, please let me know.

    Yeah. The HGHQ has a bit worst qulity than the SPBQ. However, it is mp3 stereo backwards compatible and moreover, it is Dolby Pro Logic II compatible!
    So when you play the sound with your DVD player, your amplituner
    should decode the stream to multichannel (in a DPLII manner).
    Ofcourse DPLII is not as good as digital multichannel formats (such as Aud-X, or AC3), but still,
    HGHQ seems to be a good compromise of quality and flexibility.

    Yes. Optimizations of the encoder is something that we are working on.
    But in general this is a very complex process, consisting of tens of FFT computations per frame, and nonlinear DSP operations, so a bit of patience
    is necessary

    Here is an example of STDQ 128 kbps surround quality,
    (encoded by one of Aud-X users):
    http://www.megaupload.com/de/?d=XZB5X0N4



    To unpack, you'll need a 7zip software:
    http://ovh.dl.sourceforge.net/sourceforge/sevenzip/7z432.exe

    To play it in surround, you'll need Aud-X 1.1 codec:
    http://www.aud-x.com/index.php?option=com_remository&Itemid=34&func=download&filecatid=1

    Use (for example) BSplayer to reproduce the AVI with Aud-X DirectShow decoder. Chose 5.1 output in the decoder to hear surround sound.

    Aud-X v. 1.11 has been released.

    Changes in this version:
    [1.11] - Fixed problems with FFDshow compatibility for 48 kHz mp3s
    [1.11] - Ampliutude autonormalization (causing problems) removed.

    Thank you.

  12. cool, im keeping a VERY careful eye on this program, i think it has great potential....particularly if combined with x.264 for a video codec...im just wondering if my pc would choke with that kinda encoding though, seeing that x.264 is a bit resource heavy....

    Yeah. Aud-X is a bit heavy too...
    But I hope the processors speed
    will increase within couple of yeas (?).
    Many years ago, playing mp3s was a
    heavy duty task for PCs...
    And now...

    Anyway, thanks Jeremy for using our stuff

    There are two ways to convert the AC3 to Aud-X

    1) If you are compressing a movie, please use our edition of VirtualDubMod
    (available from download section @ www.aud-x.com)
    to transcode the video stream and the AC3 stream to Aud-X.

    2) Use BeLight to convert the AC3 to 6 channel wave
    The resulted wave is compatible with our frontend input.
    http://corecodec.org/frs/do_download.php/195/BeLight-0.21.exe?ticket=3a189237ea433d5c2...ire=1138778421

    -------
    In case of second (indirect) conversion, I strongly recommend using BeLight,
    because it produces a correct channel order in the PCM (compatible with Aud-X).
    There is no standard for the channel order, so using other software may result in incorrect Aud-X encoding.
    Can you be a bit more clear on this? What I am trying to do is Convert an .avi with 5 or 6 channel AC3 audio to use your Aud-X Codec. There are four different ways from what I can tell to extract a 6 channel wave with BeLight. (on the WAV/PCM tab you can select DD-WAV, 16bit 5.1 Wave, 16bit (six) Mono Waves, or 32bit (six) Mono Waves.)

    I answered my own question through trial and error. It is the WAV/PCM Tab, WAV, 16bit 5.1 Wave that is compatible with the Aud-X Frontend.

    Yes
    Interestingly, Dolby Digital wave is in fact AC3 in the stream SPDiF format...
    This was meant for playing DD sound from a CD disk in a DVD players (I think).
    During this weekend, we will generate new guids with detailed information
    on how to perform several conversion, including conversion from
    mpeg4 movie (Xvid/DivX) with Aud-X to playable DVD disk with mpeg2 and AC3.

    For some reason this file will not play with the Aud-X codec installed. After removing the codec the file plays as normal.

    Is there a way to set the Aud-X codec to only operate when Aud-X encoding is used? Once this was installed it was Decoding or Post-Processing the audio in all .avi files as far as i could tell.



    Again, this movie was not encoded with the Aud-X codec, yet will not play with the codec installed.

    We are planning to add a switch to diable/enable Aud-X.
    Currently, if you are using FFDshow, you may choose DirectSound output in that filter. It will disable our codec. I hope this solves your problem.

    BTW. please check which output option is chosen in Aud-X
    (make sure that you've chosen stereo, if you have a stereo speaker set,
    or 5.1 if you use a surround sound card. Chosing SPDIF makes only sens for conected external home theatre system.)

    On my PC I have Aud-X installed and have stereo output selected. On my Media Center PC which is connected to a DD Reciever via SPDIF i have SPDIF enabled. The video would not play on either machine with Aud-X installed. I re-encoded the video with Lame MP3 using 48000 Hz, 128 kbps CBR, Stereo and the video is now playable on both machines. Here is a GSpot screenshot from the newly converted video.



    It looks to me that the Aud-X codec has a problem decoding MP3 VBR.

    Hi, posssibly.
    In case of mp3s of 48000 Hz there is a filter conflict and the decoding
    is taken over by Aud-X. I must check the VBR decoding isssue.

    Thank you for the bug report.

    OK, I have encoded mp3 48 kHz VBR and it seems to work just fine.

    I.e. I have only tested the mp3 file with filtergraph.

    In general, there is a problem with VBR streams and AVI file container.
    So maybe your problem is related to this issue (it is better to use CBR audio
    in AVI movies)?

    I have posted this request through sourceforge,
    but I would like to know what other users think about such approach
    (I think this is the least confusing and possibly the most stable apprach)

    -------------------------------------------------------------
    Currently Aud-X MP3 5.1 is available as one of the mp3 decoding libraries
    (so now it is classifed as a regular MP3 decoder)

    My request is:

    1) Please, add new format: Aud-X MP3 5.1 to the format list.
    The user will be able to chose audxlib or disable the format.

    ---- If Aud-X MP3 5.1 is selected:
    audxlib.dll would be used ONLY for Aud-X streams.
    For regular MP3 streams other mp3 decoder would be used (selected with the MP3 format drop list)

    ---- if not selected, audxlib.dll would not be used.

    2) Please add description to "info & debug"
    about the mp3 5.1 stream (if it is such).

    -------------------------------------------------------------

    Please share your thoughts within this forum,
    but also here (in order to request changes on SourceForge FFDshow project page):
    http://sourceforge.net/tracker/index.php?func=detail&aid=1485338&group_id=53761&atid=471492
    Thanx very much. 8)

    What you have creted is awsome!!
    I have been searching for something like this for last one year which could create 5.1 AC3 Surround(even if pseudo) out of sterephonic audio.
    I do video capture in mpeg2 with audio in 2 channel stereophonic mp2 format. Is there any way to feed direct mp2 to this program for getting 5.1AC3 or do I need to go mp2(2Ch)->mp3(2Ch)->AC3(5.1Ch)?

    Indeed, our directshow filter does some realtime stereo->5.1 conversion
    (e.g. pseudosurround, or dolbyprologic decoding), but I do not think
    that you can use it for file conversion. Only during playback.

    However, if you are interested in stereo->5.1, please follow this link:
