    hi

    I use divx or wmp for playing a downloaded avi file. video playback is ok but the audio is the problem. th background music and the sound effects are way more louder than the actors conversations. so i cant hear the dialogues without waking up my little kids or using headphones.

    please help me out here.
    thanks

    I suggested this method on another thread and maybe itll help you.

    Download the AC3filter and mess with the settings until you get the dialogue audio at the volume you want. Im sure you can even lower the volume of the backgrund music or special effects. Id like to note that this is only a decoding filter so if you uninstall it, or use some other ac3 codec to decode your audio then your problems will return.

    Heres another link with some uselful documentation:
    http://ac3filter.sourceforge.net/

    So what is your audio file?

    Use GSPOT to find out.

    The only option i can suggest right now is to convert your mp3 audio file to AC3 and then to use the AC3filter to decode the file.
    Here is a guide:
    http://www.dvdrhelp.com/forum/userguides/129419.php

    There is another method i will work on and if I get satisfactory results I'll post it here.

    alright the guide is great. but i have one small problem. the besweet only works with the audio files and i dont know how to extract the audio file from the avi file. Is there any decoder which takes the avi file and decodes its video and audio.

    Oh I assumed you knew how to do it.

    Download Virtualdubmod and load the avi file. Go into the streams menu and click stream list.
    Youll find your audio here. Click on demux and give the file a name. Convert the file to ac3 and load the avi into vdubmod again, and get back to stream list. The original audio file should still be there so click on disable to well....disable it, then click on add and select the newly created AC3 audio file. Click ok and get into the video menu and make sure Direct stream copy is selected. Save the file as an avi.

    ok thanks for the detail instructions.

    everything went well but there is one little glitch. :)

    I converted the mp3 file into ac3 and when i was adding to the movie Virtual dub said that its not valid format. apparently besweet has a problem. well i am posting the log that i got at the end of encoding.

    I dont think its Beseet thats causing the error.
    Are you using VirtualDub or virtualdubmod?

    VirtualDub doesnt handle AC3 audio, while vdubmod can.

    is there any other decoder that can do that?

    For some reason I cant get into dvdrhelp.com to check the guide.

    Ok what version of besweet do you have?
    Is it 1.4? If not download it from here:
    http://dspguru.notrace.dk/BeSweetv1.4.zip

    Im really not sure what the exact settings are with the guide, but Ive created an ac3 file using my own settings and it worked. Try creating the file this way:

    Input---your mp3 file

    Leave everything at default except for AC3ENC, make sure it's set to AC3.

    Click on the MP3 to AC3 button.

    Thats all I did and I was able to mux the file with my clip.

    No Im not aware of any other program that can do it. Though besweet seems like the best way to go about this type of conversion.

    You should use the stable release. The one on the link i gave is stable.

    I used the guide on an mp3 I had using the stable release of besweet and there were no problems with muxing the new ac3 file with virtualdubmod.

    BTW what version of virtualdubmod are you using?_X_X_X_X_X_[small]Life is but a dream...so wake me up already!!![/small]
