AC3 to AAC/MP4 with foobar2000

I think one can conclude from KpeX post that one won't hear the difference between azid.dll and liba52. But it is also true that azid offers much more options. These are my feelings on the issue. I doubt that one could ABX a liba52 decoded wav versus an azid decoded wav....but there's only one way to know for sure. IMO azid's impressive amount of options is one of the main reasons besweet should be used to transcode to Nero 5.1 AAC, the other being that it correctly resamples as the encoder requests.

But lately I find myself using FAAC more often than Nero. Hopefully this will be supported in BeSweet one day soon :)

FAAC's development seems to be at a standstill since knik's departure, but hopefully someone will pick up the torch.

Agreed, I'd hate to see the project die, especially with the quality improvements as of late. It is likely that the project will attract more developers however, since it is the major open source aac project.

i tested besweet to foobar alot for ogg and aac. foobar won on ability to use different versions for ogg and aac and simplicity of batch encoding. does anyone know a site like rarewares that release new ogg libvorbis file? cli encoder gives you the ability to use floating files also, but they cant be longer then 1.5 hours for some reason.

i get lot of stereo collase if i use besweet/nero also for some reason yet when i use foobar it comes out perfect for low bitrate he-aac? kpex do you use the foobar input for faac? i gave it a few try quality was good.

Libvorbis is available on rarewares in several versions, and also on the xiph/vorbis homepages.Originally posted by jimmy basushi

i was talking about playback i used to be able to hear a slight difference but i havent tried it again for a while. stereo collapse = when you hear both channels sounding like mono for a tiny second.
i look at rarewares, i cant get one like aotuv. only gt3b2 and 1.0.1

Sorry, but what does this have to do with AAC? Both aotuv, gt3b2 and 1.0.1 are Vorbis encoders, i don't get what do they have to do with this subject...

Anyway, you can find aoTuv here (http://www.geocities.jp/aoyoume/aotuv/)

[mikeson]

So may I ask what more experienced users that I am recommend?

Transcoding via BeSweet AND downsampling or transcoding via fb2k and NOT downsampling? What do you think is more effective and in which way can we achieve better results?

[KpeX]

I wouldn't say one is clearly better than the other - however, when using BeSweet you have more options and you are using the Nero AAC encoder as its developers intended.

in pervious post, we talked about getting different ogg versions look back. and that link doesnt have libvorbis dll's that besweet uses? i try downloading them all.

and on audio test, i work out why aac sound strange.. it was a dshow problem.

[porcinemodjo]

i realize this post will be breaking a couple of rules here...but im really on the edge.
Apart from the fact that tiki says this guide is no longer valid, i used foobar to encode an ac3 file to an HE-aac with the nero plugin. However, the only option for HE-aac caused the output to be in the form of an mp4 file. I tried demuxing the aac from the mp4 file with ivan and menno + mp4creator, but it creates a batch file which doesnt work.

I also saw the option of muxing the mp4 file itself with my xvid encoded avi file, but i want my final file to be an avi and not an mp4.

The thing is that ive done this before, but i cant remember what i did to do it. Something to do with matroska. Im sure the answer to my prob is littered all over the forum, but i dont now WHAT to look for exactly.

to summarize:
1)can i get the nero plugin to give me an aac file instead of an mp4? how?
2)or how else can i demux my mp4 to its aac file
3)or how can i mux an mp4 file into an avi

I would appreciate any help.

PS im a real noob, so be gentle :(

Actually all your questions would be solved if you would read AAC FAQ (http://forum.doom9.org/showthread.php?s=&threadid=68300#post424070) and MP4 FAQ (http://forum.doom9.org/showthread.php?threadid=62723).
It's very popular and interesting to read!

1) There is Export ISO 13818-7 in Nero encoder.
2) Foobar2000 can do it too. I don't remember how this option called. Just click right button on mp4 file and you'll figure it out easily.
3) Both mp4 and avi are container formats and you can't put one container to another.

1) In Nero encoder settings set Export ISO 13818-7. This will give you mp4 and aac.
2) AVImux can mux AAC's to AVI.

[porcinemodjo]

thanks to all for the help...the Export ISO 13818-7 did the job. I had tried it earlier, but when i checked the o/p directory while it was encoding, i only saw the mp4 file, so i cancelled the conversion. I didnt kow it created the aac file after completion of the mp4.

Thanks to all once again.

It should look something like this: -

i have an ac3 file which has a delay of -49ms, so how to set delay in foobar2000?

You don't need set delay in foobar2000. You set delay in mux program (VDM, Avimux, etc.). I think that every mux program has this feature.

[killerhex]

can foobar encode AAC 5.1 back to AC3 5.1
for ac3 is easier to decode when playing back

Yes, of course, but you need free ac3 cli encoder called Aften.

As it is possible convert to MP4/AAC(Multichannel) if foo_nero.dll any more does not work with the new version Foobar2000 0.9.x

Use NeroAacEnc free and better than old dll method.
