Does anybody still need 3GPP AAC+ Reference Encoder

andy

Hi!
3GPP AAC+ Reference Encoder provide quality near to early WinAmp CT AAC+ encoder but it is slow. Does anybody need it at all (there are free WinAmp CT AAC+ encoder avaluable)

For cellphone becouse using mp4 container. Don't worry i tried to use mp4box but my cellphone reject nero/ct mp4 files

Reference encoder produce 3gpp format (not pure MP4)
try to play with MP4BOX to obtain same format
tip:
use mp4box -info filename to obtain detailed information

OK. First I using some 3gp referemnce in BeLight is that same or not in BeLight i get mp4 output and in winamp info box says thah correct information about this mp4 like HE-AAC not LC-AAC like Nero or CT. Second what point of this question at all. Third why you should add CT encoding in megui.

actually this is 3gpp file but with mp4 extension.Originally Posted by shon3iand in winamp info box says thah correct information about this mp4 like HE-AAC not LC-AAC like Nero or CT.

This is known WinAmp issule. Try alternative input plugins or use Foobar 0.9 RCOriginally Posted by shon3iThird why you should add CT encoding in megui.

This is planned feature, it will be added right after Doom9 complete MeGUI refactoring.

Ok thanks for this information.

I ask you what intention with 3gp encoder

Some times ago I perform some 3GPP Reference Encoder modifications to allow read data from stdin etc... (this version is used in BeSweet/BeLight)
Unfortunally I lost this source code (my HDD was broken    )
So I trying to understand - if anybody still really need this encoder I can reproduce my work from scratch in order to add 3GPP Reference Encoder into BeHappy/MeGUIThat was be nice but there is not necessary to doing this. Becouse i always encode to 6ch with CT when encoding movie and litle Nero 6/7 beacouse have broken 6ch encodings. I only use that 3gp for cellphone but sometimes bagging me and i still use standard mp3. It will be cool if you make some improwments with 6ch audio.

AFAIK MeGUI (when using AviSynth audio) contains special workaround for it (wrong channel order). Can you check it and report a bug is something is wrong?

Talking about 6ch in 3GPP AAC+ Reference Encoder I must say - I spent a really many time to achive it (and I will very close to it). I does'nt think I can find to much time to repeat it again - I think it's better to spent this time to BeHappy/MeGUI improvements instead...

By the way:
there are new version (Dec 2005)

Code:
2005-1230SP-0507860027Correction to C-code: encoder bitrate switching simulation toolset6.4.06.5.0
2005-1230SP-0507860028Correction to C-code: encoder tuning table entry for 44.1 kHz was wrong6.4.06.5.0
2005-1230SP-0507860029Correction to C-code: fix to make decoder more robust against corrupt input data6.4.06.5.0
2005-1230SP-0507860030Correction to C-code: removal of unused coefficients in resampler6.4.06.5.0
Binary is avaluable here: showthread.php?t=7107

and it use PS only for bitrate below 36kbps

Code: if ( (inputInfo.nChannels == 2) amp;amp; (!bEncodeMono) amp;amp; (bitrate gt;= 16000) amp;amp; (bitrate lt; 36000) ) {   useParametricStereo = 1; }

Channel order is ok both MeGUI/BeHappy and BeLight but quality in Nero 6/7 i terible, And CT is perfect. Listen to yourself  files/14365315/aac.rar.html.This archive contains original 6ch ac3 and three mp4 aac maded by Nero6/7 and CT with lastest BeHappy.

OK

Unfortunally I have a really bad ears and don't have 5.1 speakers

does you try latest beta tests/aac_48...02_feb_2006.7z

Aslo i dont have 5.1 speakers but my friend have. I tried last beta and this same i aslo try with ps/nops dll. In nero 7 when quot;hequot; started to speak i hear artifacts like a huge compression equals when compress something in mp3 at lt;56kbs. With nero 6 looks like a center chanel dominixed into L,R chanels. On 5.1 systems nero 7 in same, But nero 6 has no surround effect. CT is best and no problems with this.

WOW! Really interesting (i was never think about CT 5.1 seriously)
thanx a lot!

Wait. Let's wait for results of the public test of HE-AAC (12 of the march).  It's not clear which AAC codec provides more  optimal quality. content/?48k...0public%20test

Yes IgorC that is true but this tests is for stereo files. Can some produce test for 6ch @ 96kbs-128kbs. Enybody will see that nero6/7 can't be a good choice.

Can you use the Winamp encoder without installing winamp? I really want to use this encoder, but I will NOT install Winamp. Can anyone provide me with the nessecary stuff?

install winamp
get a copy of enc_aacplus.dll
uninstall winamp
volia!

I guess I'll try it. I can always manually clean out whatever it does to my precious registry .

BTW, I always wondered what the difference was. Does 3GPP not have PS? I know CT has it. And 3GPP is stereo only.
