aften - a new CLI AC3 encoder
A new AC3 CLI encoder is born :) :
http://sourceforge.net/projects/aften Code:
usage: aften [options] <input.wav> <output.ac3> |
FFMpeg based :?: :roll:
-kwag |
Even if it would be the case, the libavcodec AC3 core has been fixed since some month: http://forum.doom9.org/showthread.ph...133#post812133
:) But imho that one above is libavcodec independant. |
I'm not sure that this settings is smart :

Note: release 0.04 8O Are you sure it is really born ? :lol: |

Isn't your dynamic issue more related to DRC or Dialognormalisation ? As both do affect the dynamic as a whole. |

DialogNormalisation, for sure not. DRC maybe. Whatever the result is the same : the center is too low and you have to change all the settings each time you change your DVD. Very boring. |
Did you take a look at "BeHappy"?
Its very useful for Audioencoding. When importing an audio file, it generates a temp. avisynthscript where NicAudio.dll's audio import functions are used to properly decode the source, even 5.1ch. Finally BeHappy pipes the avs resulting audiostream to the selected audio encoder binary internally via commandline where finally your desired target result will be on disk. So, as it does generate a temp avs file maybe its possible to use avs commands for altering the amplitude of a specific channel. In your case the 'center' one. Im not shure if BeHappy permits direct imports of avs scripts with the specific volume mods already done, but even if not, you can use BePipe. Generate avs script -> use Bepipe to pipe to the desired target encoder binary (ffmpegAC3, NeroAAC, ffmpegMp2) -> target audio encoding will be on your HD. As avs is capable to frameserve the 6 channels of a 5.1 ac3 source by using NicAudio.dll then such a workout would be no problem. Hmmmmmm .... anyway ... I wanted to test the new binary stream piping capabilities of PureBasic v4, maybe its time to crack that nut on an audio transcoder, similair to BeHappy. It would use an embedded binary of ffmpeg for everything: AC3 (ac3enc, which is fixed since month), mp2 (mp2enc), aac (libFaac) etc., "aften" could be used as an optinal ac3 encoder and NeroAAC.exe as AAC alternative. (just thinking) So do test BeHappy/BePipe and tell me what could be done better. But ... actually time is not my friend, so paaaaatience ;) Edit: Not Needed as it seems that aften is supported by BeHappy and also a GUI is available: http://forum.doom9.org/showthread.ph...ighlight=aften http://forum.doom9.org/showthread.ph...ighlight=aften |
Excuse me Inc, can you point a more direct link to Behappy ? I must be blind... :oops:
Edit: Ok, found the author's name (Dizon) and signature ;-) |

Is there a link to the sourcecode? I got on my Win2000 partition a VS2005 incl. beside c++ also c#, so maybe .....

The zip contains both binary and sources.

Hi guys :).
Just downloaded Aften. BTW it is now at v0.05. I was wondering. I would like to have a CLI (or GUI with CLI/batch as optional) transcoder for those 2 movies DVDs that sometimes I still burn. You know, if audio bitrate is not the same for both movies then Muxman will not work. I know BeHappy but that _is not_ an easy tool to set up. Aften doesn't seem to have that transcoding feature as it supports only wave as an input. Is there anything out there easier than BeHappy for this transcoding purpose? Cheers |
Just forget it.
I just made BeHappy work easily at first try. But I gotta use FFMpeg engine because if I try to use Aften as the engine it keeps hitting me with error messages. Maybe I really can't transcode AC3 to AC3 with Aspen even inside BeHappy suite. BTW, does someone know if I can control BeHappy from the command line (CLI)? I can't find any readme.txt or proper documentation to BeHappy and I tried BeHappy.exe -h|-? and it didn't work as expected. Any help is greatly apreciated. Cheers |

Hey Andrej :).
Thanks for the nice tip. I'll look into it ;). Cheers |
