command-line frontend for WinAmp AAC+ v2 encoder (upd 2006-05-15)

[wammie]

It seems this front end cannot be invoked by Exact Audio Copy as an external program. In my attempts, the DOS window opens very quickly and then closes. I have been unable to capture any messages from the DOS box, even with a screen capture, as the window appears only for the briefest moment.

Is there a way to use this program from Exact Audio Copy? I understand the developer would not and should not need to make this compatible with everything else out there, but if anyone knows how to make it work I'd appreciate some help.

Winamp5.2 AAC+v2 encoder command-line frontend (new version)

http://img247.imageshack.us/img247/4605/dibujodd8ow.gif


Support for AAC-LC encoding via CT encoder
6ch support
support aacPlus HE-AAC High-Bitrate Encoder

enc_aacplus.dll from WinAmp 5.2 beta requed (tested on build 365)

new version contains some bugfix

Get it @ BeHappy Workspace (take look @ my signature)

[Gabriel_Bouvigne]

It seems to me that there is no way to choose between channel modes in this version.
--chmode is not parsed.

[dimzon]

It seems to me that there is no way to choose between channel modes in this version.
--chmode is not parsed.
ParametricStereo will be used for he-aac @ bitrate <=48kbps
JointStereo will be used otherwize

Does anybody need addittional modes? I can add it during next week

[Gabriel_Bouvigne]

Yes, I saw in the source code that it was using default settings according to the bitrate.
As you provided source code (thanks a lot), I modified it to be able to specify channel modes, so it suits my needs.

Can You share modified binary and source (to save my time a bit)?

[Gabriel_Bouvigne]

Well, it's just:

if(0==strcmp("--chmode", argv[i]))
{
nChannelMode=atoi(argv[++i]);
continue;
}

It's your mistake ;)

try HE 96-213kbps


HE High (Higth doesn't mean hight bitrate but hight samplerate) doen't supprt 6ch

So You must use HE-AAC (Not HE High) (96-213) or LC-AAC (160-320) for 6ch encoding

[aiyunyi]

Can this cli and enc_aacplus.dll be used alone without winamp?

surprisingly, i find it in kmplayer!

[joynes]

When i encode an 44 kHz wave sample with --lc from enc_aacplus.exe the result will be downsampled to 32 KHz. Why is this? Is there some way around?

Hi! sry didnt see your replay earlier.. well my bitrate is 64 Kbps...

That is normal because that is too low bitrate for LC profile (encoder try to prevent how much more artifacts from audio), better than you use HE profile instead

[gameplaya15143]

dimzon, did you ever figure out how to add the resample option again? Remember your really old frontend could do it. ;)

Ok i see :)... but I thought it was a common format for mobiles: 64 kbps/44 Khz Samplerate AAC LC...

i tried with neroAacEnc.exe from Nero digital which could preserve the samplerate. Is this encoder better for this sort of work?

Yes, but have little whrost quality than ct.

New Coding Techologies AAC encoder is released with new version of Winamp 5.3

LC-AAC now have PNS and is optimized for speech, and have down to 8 kbps

http://img231.imageshack.us/img231/9518/ctaacdi4.jpg


HE-AAC and HE-AAC High as optimised only with speech, and aslo have bitrates down to 8kbps, and devs says that encoder have big improvments in low bitrate encoding (I tested at 48kbps and sounds better than old version, maybe now can beat nero :D)

http://img218.imageshack.us/img218/8054/ctaac1uj9.jpg

Stereo mode now can be only Joint Stereo or Parametric Stereo, oterwise can be Mono or multichannel.

This enc_aacplus.exe works good with this new version of enc_aacplus.dll.

Dimzon can you implement this new features and remove old, and update BeHappy Dialog (With rounded bitrate)! Please.

[Kurtnoise]

http://kurtnoise.free.fr/index.php?dir=misc/&file=enc_aacPlus_20060927.zip

Prove it instead of trolling...

[shon3i]

Thanks Kurtnoise for build.

Prove it instead of trolling...

IMO CT AAC is always sounds better than Nero especialy in multichannel encoding. My ears proved to me


EDIT: Sorry Kurtnoise but looks like encoder support all stereo modes which means Independet Stereo, Joint Stereo, Dual Channel, Parametric Stereo, but IS and DC is removed from winamp beacuse confuse ppls. So please if you can back --is and --dc switches

[shon3i]

Here is package who contains enc_aacplus.exe compiled by me, and enc_aacplus.dll, nscrt.dll, and source code.

http://www.box.net/public/n1y5sea9fl

The different from Kurtnoise build is, again it have --dc i --is switches, which means you can use again Independet Stereo and Dual Channel mode.

Where does mp4mux come from ?

Where does mp4mux come from ?
Ateme beta test, original filename is mp4muxer.exe.

[gameplaya15143]

:( still no option to set the output samplerate?

[SealTooGreat]

Ateme beta test, original filename is mp4muxer.exe.
Is it Ateme's mp4muxer?!...or it's opensource?!

[shon3i]

:( still no option to set the output samplerate?
Did you mean resamle option for LC-AAC audio?

I realy don't know why you need that option, coz bandwith will be same. For everything under 96kbps better to encode as mono if LC-AAC used, or use Nero encoder, because is better optimised from 64-96kbps range.

Is it Ateme's mp4muxer?!...or it's opensource?!I relly don't know, maybe is nero muxer, but app is not opensource, and i use it from package who is linked on net, ateme 1.0.1.28 ;)

[Kurtnoise]

yeah...thanks to share something completely illegal.

3GPP Encoder with 3 cbr stereo encoder options:
- 64 Kb/s HE-AAC
- 48 Kb/s HE-AAC
- 24 Kb/s HE-AAC + PS
Can't be compared with CT aacPlus encoder.
Tinymp4 is a player, tagger, multiformat stereo decoder, ... but here speak only about encoder.

@shon3i
To avoid the problem about the legality of mp4muxer use, maybe we can preserve the old option
--mp4box
and add now, instead --mp4:
--mp4muxer

Then legal owners of mp4muxer can use it, and the rest of users continue with the free mp4box. Enc_aacplus only need send the job to mp4box or mp4muxer with the appropriate parameters.

BTW, when change the parameters all app using the tool must be changed. At least BeHappy and MEGUI must be changed to use this new version. Maybe the old parameters must be maintained for compatibility, like:

--br, --cbr
--he, --nops

[shon3i]

To avoid the problem about the legalityThat is true, but this package is 3 years on internet, and probably many ppl's have it, aslo there is not any eula in package, so i don't care of any rights.

Then legal owners of mp4muxer can use it, and the rest of users continue with the free mp4box. Enc_aacplus only need send the job to mp4box or mp4muxer with the appropriate parameters.That isn't problem, but i don't wont back to mp4box, because is over 1mb, and i haved much problem's with mp4box mp4's files http://forum.doom9.org/showthread.php?t=111224, not only with my standalone, aslo with winamp and foobar, now for example 6ch mp4aac in foobar 0.9.4.2 have some troubles, muxed with mp4box.

Nero, Winamp, mp4UI, mp4muxer, muxers don't have these problems.

I will go round mp4box until not solove this problems.

BTW, when change the parameters all app using the tool must be changed. At least BeHappy and MEGUI must be changed to use this new version. Maybe the old parameters must be maintained for compatibility, like:

--br, --cbr
--he, --nops

--cbr, can be added as alias, but --nops don't have sense coz --ps is now used for PS encoding.

I will update BeHappy package ASAP, so there is not problem, i realy don't care about MeGUI, because that is 10 minutes job to change switches. I know that MeGUI devs don't love CT AAC because it totality illegal, and don't have much capabillities as nero encoder.

[gameplaya15143]

Did you mean resamle option for LC-AAC audio?No, I mean like what was available with dimzon's first version of the frontend (which was lost way back when his hdd died). For example, input could be 44100hz stereo, and the output could be set to 24kbps 16khz HE+PS ;)

I don't know if it is even still possible with a newer version of enc_aacplus.dll, I just know that old frontend does it just fine with an old version of the encoder dll.

The link for the old frontend was (which still seems to be working) http://www.crapshack.com/aacenc.zip



I've never had any playback issues using mp4box and winamp (using ct in_mp4.dll not the nullsoft one)

[Jongan]

Not really,Tinymp4 is also a aacPlus encoder, it use DirectShow to decode multiformat and use 3GPP encoder to build aacPlus stream. And use Tinymp4 any other format except mp4 to be converted to mp4. Please take a look of this,Thanks.

Ok I say:
"Tinymp4 is a player, tagger, multiformat stereo decoder,..."
but DirectShow isn't the better way to control the decode step.
and use 3GPP encoder to build aacPlus stream.
And I say:
"3GPP Encoder with 3 cbr stereo encoder options:
- 64 Kb/s HE-AAC
- 48 Kb/s HE-AAC
- 24 Kb/s HE-AAC + PS"
Can't be compared with CT aacPlus encoder with bitrates until 320 Kb/s and multichannel options. About the quality you can see the tests in Hydrogenaudio Forums, 3GPP is below CT and Nero encoders.

Use "-isma" in mp4box's cmd line. It will add tracks (0D & BIFS), like mp4UI/Winamp does by default.
