Besweet vs Headac3che-question

[mgh]

Used DVD2AVI with a VOB clip (approx.4 minutes)
When I demuxed and made an avi with virtualdubmod with the audio left as ac3-there was no sync problem.
When I asked DVD2AVI to decode the ac3 to wav-I could not get the audio to sync using mpeg layer 3 compression.
Converted the ac3 to wav with besweet. Again no sync.
Converted the ac3 to wav with headac3ache-no sync problem whatsoever.

Another weird thing-i was trying to use wma for audio with avi. Was getting clipping-even after using amplifydb(-20) in avisynth. No such problem with encoding to other codecs. Tried to convert original audio to wav before encoding. Clipping continued. Used headac3ache to convert the original audio to wav-the clipping disappeared.

Question-is headac3ache a better converter to wav than besweet in general-or were these exceptions??

As far as I know they both use Azid to decode/convert the AC3 stream to WAV so results should be the same.

Headac3he will automatically add the offset to the encode and I don't know if BeSweet does it automatically. That could be your problem.

Also, I would suggest using DVD2AVI to demux instead of vdubmod.

I use Goldwave to convert AC3 to wav.

I use DVD2AVI to demux vobs and get the d2v file for avisynth.
The problem I mentioned does not occur with most vobs. I normally ask DVD2AVI to convert the audio to wav and then use it. 99% of the time there is no problem. In this specific case , there was.
Thanx for the replies.
