How To Convert AC3 Dolby 48000HZ 6 channels to MP3

[benchur]

My DVD player sony ns32 can deal only with mp3 files
i can't convert the movie audio : AC3 Dolby 48000HZ to MP3 5.1 to mp3 ,
tryied with virtual dub (have ac3 codec )and avidemux

i always try to avoid a solution that deal with ripping audio from movie and attach again after conversion

[guns1inger]

Install the LAME ACM MP3 codec and you can use virtualdubmod.

Why doesn't avidemux work ?

[redwudz]

It probably doesn't make any difference with your present problem, but if I am converting a DVD to a Xvid with MP3, I choose the two channel audio (Stereo), not the 5.1 audio from the DVD, if it's available.

And welcome to our forums.

avidemux 'says' bistream detected

and source video is:

AC3 6 channels
56000 BPS /448 bps
48000hz

i choose lame 224 kbit ( cause 448/224=is an integer )
save as video

results perform slow audio bass sound
have ac3 codec on virtualdubb but it doesn't work for this case
I think the problem is the 6 channel or the high sampling rate

You can use my application... it's called DAudioK.
You may need to install AC3Filter.

Thank you

forgot to mention that source video is xvid and not dvd

[guns1inger]

Video source is irrelevant

When you choose to encode the audio, do you choose 48 or 44.1 kHz sample rate ? If you choose 44.1, try keeping 48 instead.

Of course , 48hz but problem remains , tried avidemux with dolby or 5.1 filter doesn't help
the AC3 codecs of virtualdubb reach only 324 samples

[MOVIEGEEK]

AC3Tool

1. The source is xvid only try to convert to ac3
2. On virtualdubmod there is no audio menu, but succedded to get more details on audio :

valex ac3/ dts codec , atsc a-52

the ac3tool demand to extract the sound from the video?

[Cornucopia]

As MOVIEGEEK already suggested, us AC3TOOL.

1. Demux the AC3 from the AVI using VirtualdubMod or AVIMux-GUI (demux the video also at this time).
2. AC3TOOL: AC3->WAV, keeping 48kHz, downmix 5.1->2.0
3. AC3TOOL: WAV->MP3, keeping 48kHz, use 128-256 kbps (your choice). I like 192 for 2.0ch.
4. Mux the MP3 in with the demuxed video to new AVI with AVIMux-GUI.

That's it.

If nothing else works, download:

1) Unzip, place AVI file into same folder (AVI must NOT have spaces in the name). Click .BAT file to run.



2) When Completed..

During the Demux Mux process on the first choice :
Can i expect to see ansync between video and audio adter Mux ?

And if so what can i do then ?

I can't find an audio menu at the software

[DarrellS]

In VirtualdubMod, it's under streams > stream list.

If you use Audio-X, there is an Audio-X version of VirtualdubMod.

It's listed on the page that I linked. Here is the file...

[benchur]

choose stream list but doesn't see the ac3 to mp3 codec ,the aud-x appear as a separate
software

[DarrellS]

Aud-X is a codec

Streams > Stream List > Right Click - Full Processing Mode > Right Click - Compression > ( Select audio compression ) Aud-X 5.1 > Standard quality [mp3 128kbps compatible], 48kHz, 5.1
