vdub error with sound

[dazndan04]

hi ive tried seraching for this problem but couldnt find a deffinite answer... here's the situation:
anime ep which is a dvd rip converted to avi with AC3 audio.
i can play the eps perfectly fine but when i put it in vdub to convert the sound to wav i get an error message: "No audio decompresser could be found to decompress the source audio format". im trying to get it to wav so i could put the video on dvd and audio is much easier when it in wav to encode... or can u do a dvd audio with ac3?

edit: when put i gspot it gives me some whack info:
video is wmv3
audio is 0x00ff <unknown> but codec is installed with CoreACC audio decoder

Ac3 acm decompressor will do the job but just leave the audio as ac3,no need to convert for dvd compliant files.

[dazndan04]

i installed the acm compresser and it still doesnt work.. do i need to install something else?

If you plan on converting to DVD there's really no reason to recompress the audio at all. It's already DVD compliant. Save it as wav in Virtualdub with "direct stream copy" enabled in the audio menu and then run it through AC3fix to correct the header.

i tried a little test clip of the anime with tmpgenc straight from the video source but no sound would come out and when i tried to specify the sound as the avi it gave me some error message
and i cant save it as a wav in virtual dub, thats my problem to begin with

[johns0]

You dont need to convert the ac3 file,just direct stream copy and rename to ac3 and use ac3fix on it,the ac3 compressor works for me.

[dazndan04]

direct steam copy? how do u get ac3 fix to work tried opening it but nothing happens. do i need the source code?

[dazndan04]

oh i forgot to mention that the audio bitrate is 144kb/s which i read somewhere is not standard ac3 if im correct and the Fs is 48000 Hz

[teegee420]

In virtualdub, go to the audio menu and set it like this:



AC3fix is a command line program.

[dazndan04]

k i used ac3 filter so do i jus use like tmpg dvd author to put the video and ac3 sound together? gonna try

[dazndan04]

ok i tried to put it together but it says illegal dolby digital (ac-3) stream

[dazndan04]

totally my bad guys... i learned it wasnt an ac3 audio but an acc audio... can u guys help me wit this?

[teegee420]

God damn you! (kidding). You mean AAC, right? Open the avi with Goldwave and save as wav.

[dazndan04]

woops... yea aac... using goldwave and it works... thank you much much for this problem.. yes now all i got to figure out is by subtitling problems
