Does anybody still need CT AAC support in MeGUI

[dimzon]

Since there are 100% free and legal encoder from Nero...

[berrinam]

I haven't really tested either recently, but in the past I did find CT better than Nero in some situations (low-bitrate dialog, in particular). I have no idea whether Nero's issue with that is now resolved, but I think that it would be good to support CT anyway, just for reasons of choice. I haven't yet voted either way in the poll, because I generally keep the original audio tracks.

I think you should support Nero AAC, then Vorbis, and only after that should you support CT (if you are still interested).

with vorbis i can live even without aac (ct or nero)

anyway i cast my NO

I won't mind if it's there for anyone else who'd like to use it, but Nero's good enough for me.

oh! What does CT mean ? :o

@dimzon

Very nice additions ! btw i use vorbis only in Quality mode :)
and don't forget that latest oggenc2 build support 5.1 channel in correct order

I use the very recent .dlls of the CT's HE-AAC v2 (=SBR+PS) encoder(from Winamp v5.1 free bundle edition) with MediaCoder(in the first place, I convert the .AC3/.MP2 track(s) to 44.1 KHz Stereo PCM Wave with BeSweet) because Nero's old encoder(the CLI or Nero 7's .dlls used by The OagMachine) can give me bad audio quality(distorsions, echoes, and so on... great isn't it ?).

So I don't need it to be available in MeGUI, but other people might not want to use an "external" AAC encoder. ;)

[dimzon]

Oh Shit...
Please, provide me download link for fresh valid oggenc2

Keep in mind current build using old (improper) Oggenc 5.1 channel order

[shon3i]

1. Excelent for stereo encoding
2. Excelent for multichannel encodig
3. In my test's i think that nero's 2pass again not have better quality than CT but is useful for saving space.
4. Very fast encoder comparing to nero
5. Free ;)

Did i must say anything else, btw dimzon did you think that nero encoder will be free forever.

Aslo this oggenc2 is very amazing for lowrates and multichannel.

So I don't need it to be available in MeGUI, but other people might not want to use an "external" AAC encoder. Did you try lastest CT encoder (winamp 5.21).

[xyloy]

No, I've just updated to MediaCoder 0.3.9 and winamp v5.21, and copied enc_aacplus.dll from winamp's plugns to Mediacoder\plugins. Hope it will be even better. ^^

Much better, even that old CT from winamp 5.1 is been better than Nero 6/7 encoder. But now this CT(5.21)vsNero(CLI) is hard to say which is better.

[dimzon]

Yes, even if Nero remove it from public access You can still use previously downloaded version for free all the time...
And I really doesn't think it's possible any significant quality improvements for HE-AAC (except multichannel HE-AAC). Seems like current HE-AAC implementations is extreme close to HE-AAC theoretical/mathematical limit...

[shon3i]

OK but you must say that HE-AAC and multichannel is now best solution for 1cd rips, if we want keep 5.1, which is 100% supported by standalone players in near future.

I think that Nero make free encoder because he want a first place in aac encoders and catch more customers, but there is one limitation over encoder, 2pass and stdin. Maybe i wrong but i think, when new nero encoder came out this feature not be implemented but in nero app's will be. I again say maybe i wrong but we see.

Since there are 100% free and legal encoder from Nero...are you sure that it will be updated and freely available in the future too?

[Doom9]

are you sure that it will be updated and freely available in the future too?You can ask the same about the winamp aac encoder.. only faac is guaranteed to remain freely availab.e

[xyloy]

Mediacoder is open-source(as is faac), hosted on Sourcefourge, and all the latest plugins and .dll files are installed with it.

So it's also "guaranteed to remain freely available".

Actually, the Nero devs have publically admitted that they don't think the encoder is tuned nearly as well as they think it could be, that much more research needs to be done, and I'm a lot more inclined to trust them. (Especially after Lame went from "peaking" mp3's quality years ago, when it was widely assumed mp3 could never compete below ~192 kbps, to about tying in quality at 128 now. AAC should theoretically be able to slam it out of the park compared to MP3.)

Listening Test at 48Kbps

Nero and CT are tied in this test

Some people may prefer CT but Nero is offering comparable quality.

I would not use CT now Nero is free

CT HE-AAC v2 encoding is free also...

[siddharthagandhi]

It would be good to have it in anyways because it would save the time needed to mux in the Nero audio stream with the video.

having more choices for aac is always better.
as we seen in the past there are cases where one is better than the others and vice versa.

[Kostarum Rex Persia]

Well, I think that CT AAC+ should stay in MeGUI. More choices is always better, I agree with Sharktooth.

[futurex]

don't "need" it per se, i'd like it to be left in, just allows freedom of choice

Thank you! Now I see !
I say "yes". I often convert mp3 to AAC. I have just converting file with NeroAAcEnc
http://forum.doom9.org/showthread.php?t=110789

If I choose He-AACv2, I will can't choose a higher 71kbps bitrate.This option will give me a file which is 71kbps + SBR + PSN. Quality is bad! PSN seem to be useless.
With encoder comes from Winamp, I can be free to do anything. My ears : mp3 192 ---> AAc 93 + SBR. In

I use Behappy, choose Coding Technologies + high bitrate
Yes! I also don't want to decrease sample rate.
NeroAACEnc has "2-pass" option but If I use this option, I won't choose "VBR" option.
I have thought that :
- 1-pass : give encoder a general-view of source-file
- 2-pass : base on informations which observed when do 1-pass, do VBR-encoding
But NeroAACEnc don't seem to do like that

[ChronoCross]

thus far my exp is that nero beats CT at any bitrate. the reason you can't use he2 at higher bitrates is because there is no point at that BR. there is no advantage.

[shon3i]

Some people may prefer CT but Nero is offering comparable quality. I not understand why some ppls always use this graph and want to say how is nero better than ct. I am interested for 5.1 encoding and i don't see that lastest nero 6/7 are been good in 5.1 encodings until this final release not come out. So if i need 48kbps stereo than i sure use CT because for me is better.

[lazyn00b]

I voted yes because CT does better job maintaining constant bitrate when you specify it and because CT performs very well at extremely low bitrates. I prefer Nero for higher bitrates when absolute quality is most important, but that is beside the point - I like them both!

If any Nero devs read this... when are you going to fix CBR encoding so that bitrate is "right on the money" every time? LAME MP3 and iTunes AAC have no problem with this.

[jpl]

I would like to have CT to allow choice and so we are not dependant on one source for HE encoding. We don't know what future improvements from either Nero or CT will bring and it is always nice to have options

VBR chooses whatever appropriate bitrate for each frame, so what came before and after isnt relevant. Therefore 2-pass isnt relevant.

ABR can be done, by nero, in two pass. This is what you are looking for.

The Nero dev have explained this in the HydrogenAudio thread.

[thuongshoo]

Hi ! I spent 3 hours to do a comparision beetween NeroAACEnc and CT. The source file is a 192-MP3 file. All destination files is 71-M4A files
My new conclusions :
*Sound:
--- NeroAAcEnc isn't bad :D
--- NeroAAcEnc produces sound which is a bit softer than CT
--- CT with --high option will produces more solid treble
* Spectrum: I observe spectrum with JetAudio, Foobar, WinAmp. Spectrum of JetAudio is the easiest one to view because colunms is big and quite high :D.
---CT with --high option produces spectrum which isn't higher than 10khz. Very surprising ! because I use a option which name "high" :D. However, its sound still good. I can' also discrimate the difference of sound-which-is-produced-by-CT and sound-which-is-produced-by-NeroAACEnc
---CT without --high option produces a spectrum is similar to NeroAACEnc.

Behappy don't allow me to choose 71-bitrate. I ran enc_aacplus.exe in cmd window.

Yes! benefit of CT is free to do anything. I want to use the deepest VBR-HeAAcV2.
