NeroAAC & MeGUI Issue

[bonka]

Hello All,

After recently reformatting my computer, I have had to reinstall MeGUI. I have placed the NeroAAC files into the MeGUI tools folder & have pathed them into the correct directory in the options. I previously have done the same & has worked.

I keep receiving an error message when trying to convert the audio from ac3 to aac (Nero AAC: NOAAC-HE-MultiChannel-HQ-192kbps profile).

I have looked around to see if this could be a more recent issue, but doesn't appear anyone has had the same issue.

Could anyone help, please?

Thanks

what error?!

[bonka]

in queue window it will just show "error" instead of processing or waiting etc..
I'm not sure whether MeGUI can expand more on that

[Kurtnoise]

uncheck "Force Decoding via DirectShow" in the settings...

[~bT~]

^ tick or untick

remove spaces or special chars in paths/filenames.

[Kurtnoise]

that's remind me something...:p

Sharktooth, could you please check all the audio presets (I know that mines haven't) and put this option off. That will probably solve several issues. ;)

Agreed.

[Sharktooth]

will do that tomorrow. however the real issue is paths/files names. if they contain spaces or special chars the nero encoder will fail when dshow is used.
test it.

SOLVED: The issue was the DirectShow Part, which is quite strange, because I haven't had an issue with it in the past

On another note, the file names did have spaces in between...

And Thanks Guys for your help

Normalize()

I hope isn't a real script.
Use always the Normalize() after the downmix:
...
6<=Audiochannels(last)?x_stereod309..02(last):last
Normalize()
...

[Sharktooth]

@kurtnoise try directly, i mean not an avs script, (DS checked and nero encode selected) opening an .ac3 or other files when there are spaces in the pathnames.

[Kurtnoise]

@Sharktooth: the input source is the mka file containing an ac3 stream. The script used is internal, created directly by MeGUI.

@Tebasuna: why ?

[Sharktooth]

@kurtnoise: duid you test it on vista or XP? it happened to mee too. maybe there are some cases when MeGUI creates a wrong script or just windows or DS go nutz.

[rack04]

Same problem?

https://sourceforge.net/tracker/index.php?func=detail&aid=2028011&group_id=156112&atid=798476

[Sharktooth]

yes, but since it happens only to some ppl i think it's a windows or DS issue.

[tebasuna51]

@Tebasuna: why ?
(Use always the Normalize() after the downmix)

Because the coeficients in mix are calculated to avoid overflow (0.2929 + 0.2929 + 0.2071 + 0.2071 = 1)
but if peaks aren't coincident in all channels you never reach the 0 dB.

Moreover LFE and Surround channels can be far of 0dB peaks.

At last is more easy Normalize a stereo signal than a 5.1

[Kurtnoise]

@Sharktooth: it was on XP...

@Tebasuna: ok...thanks for the clarification. I'll change that.

NEED 8kbps preset for neroaacenc.exe!!!!!!

[Sharktooth]

8kbps??!???!?!? the minimum in megui is 16.
does neroaacenc support 8kbps too?
