AAC encoding

[Stan64]

there are no up to date guides and I dont find anything on searchung.. so I have to ask... What is the best way to encode in AAC?

[Tuning]

BeSweet with Nero dlls for HE-AAC and FAAC for LC - AAC.

:readrule: especially rule 12
the rules are there for a reason: there is not the best solution, it all depends on what you want to do!
for example for 128kbps, stereo apples aac encoder is great, but for low bitrates and multichannel neros encoder will propably do a better job...

What about Real/CT's AAC encoder? That's what I been using :|

[Stan64]

Oh, sorry. XD Second time. It's for my mobile phone. But thanx. Hope I get how to use them through bewseet though. =)

I have installed Nero. But where do I find those dlls and what comamndline do I need in besweet?...

Stan64,
you can use program HeadAC3 with intuitive GUI and all needed plugins you will find on DarkAvenger site http://mitglied.lycos.de/darkav/

Hope I get how to use them through bewseet though. =) If your mobile phone is not from O2 = Siemens, it's very unlikely that it will be able to decode Nero's HE AAC profile. So you shouldn't use it, because it will sound worse than the normal AAC LC profile when played back with a decoder that doesn't know how to replicate the high frequencies with SBR.

If you use AAC LC, you have more options than Nero (not free) through BeSweet, e.g. FAAC (for free, open source) that has been implemented in many GUIs (HeadAC3he, winLAME, foobar2000, GX::Transcoder, dBpowerAMP, Speek's Ivan & Menno and Multi frontend, Winamp, CoolEdit), but can also be used on the command line. Another option is Apple's iTunes of course, also for free, but quite demanding on minimum system resources (OS version, CPU, RAM, HDD space, download time).

Another important thing with AAC on mobile phones is the file format, because Nokia and Sony Ericsson phones do not understand the MP4 container, as far as I know, so your application either must be able to put out *.aac files on itself (all variants of FAAC, Nero) or offer an option to extract this file from the MP4 container after the encoding, e.g. when using iTunes to produce *.m4a files (Ivan & Menno, foobar2000, mp4creator, mp4UI, MP4Box).

By the way, there's a FAQ with a chapter for AAC in the forum about audio encoding. For more information you can also read through the Wiki on Audiocoding.com:

http://www.audiocoding.com/wiki/index.php?page=AAC

It's the homepage of FAAC and FAAD2 (the open source decoder) and has a forum, too.

I have a NEC e808 it is an old 3G phone. It can handle ARM and 3ga also. Is it any better or? It also handles wma. =D

The 3GP container format is very similar to the MP4 container, but not the same. It can also contain AAC bitstreams in a *.3gp file, so maybe you would have to use a file muxer that can handle this container format and AAC bitstreams. The only one I know for this task would be MP4Box from the GPAC project, but it only accepts *.mp4 (and *.mp3) files as audio input, not *.aac.

So the easiest solution for you would be if your mobile phone can handle simple *.aac files without any container. You can simply test this with the default FAAC settings if you can't find a related information in the manual.

the NEC e808 seems to output .mp4 audio+video files with amr audio
