converting 192kbps ac3-->wav=fine, but 448kbps ac3-->wav=audible glitch

[McGee]

I'm getting a loud glitch at the begining of a wav file after converting it from a 448kbps ac3. The rest of the wav file sounds fine, as does the original ac3. A 192kbps ac3 I had converted to ogg earlier also sounds fine. This is my second DVD rip ever.

I had been using OggMachine 0.62 with BeSweet 1.5b23 when I noticed the problem with the 448kbps ac3. I tried BeSweet 1.4 instead and it didn't help. I then tried converting to wav instead of ogg, and the glitch was still there. I even tried HeadAC3he 0.23a and got the very same glitch in the wav. I did all of this on two different computers, both running XP and both with Soundblaster Live Value cards.

The only thing that worked to convert the ac3 was the Foobar2000 audio player with the foo_ac3 plugin, which I used to convert it into an undithered 16bit wav. Now I'm trying to convert that wav into ogg with BeSweet 1.5b23, but no matter what I do I get "Error 68". HeadAC3he will work to convert the wav to ogg, but I'd like use OggMachine/BeSweet since it is recommended by the guide I'm using. Can somebody help me?

Please post your logfiles! The fact that several methods failed to decode the AC3 correctly is probably a sign that the ac3 file is either corrupt (meaning you need to rerip from DVD) or that it is a rare azid problem sample. But once again we can probably give you a lot more help if you

Seeing as that your input AC3 is only two channels, DRC, LFE>LR, and Pro Logic II downmix should not be necessary. This may not be causing your problem, but just in case, try the exact same command line but replace

-azid( -g max -L -3db -c normal -s surround2 )

with

-azid( -g max )

Next step, try decoding the AC3 track to wav using DVD2AVI. (i.e. load the .vob's, set output method to decode, save project).

Done, and the wav sounds fine.

yeap. this is a known (and pretty rare) azid bug (#3).

[McGee]

Okey doke. Thank you for the help, KpeX and DSPguru. I'll be on the lookout for the next version of azid.

[DSPguru]

my tests of v1.9 shows that this bug indeed had been fixed.

I don't think so. I get the very same problem (with the workaround you provided working fine) with besweet latest version (downloaded yesterday). Sorry I don't have the logfile at hand.

FWIW, also tried with azid latest (1.9) to do an AC3->WAV : problem persists.

Cheers,
