Are there any tools that can encode AAC+ to shoutcast from normal soundcard line-in (or whatever recording input you select)

I have found http://www.orban.com/orban/products/stream/1010_overview.html but that requires a special soundcard.

Also i have found a decoder http://www.free-codecs.com/download/CoreAAC_Directshow_filter.htm but i cant get it to work (yes i have ran the .bat file and put in system32 dir)

Anyone has some AAC+ streaming experience or is this not yet possible?

The quality is great on low bitrate!

As far as I know the software version for about $100 doesn't depend on the soundcard, only the professional version for several parallel streams and audio processing comes as a hardware solution.

Also i have found a decoder http://www.free-codecs.com/download/CoreAAC_Directshow_filter.htm but i cant get it to work (yes i have ran the .bat file and put in system32 dir) If you want to listen to aacPlus streams with WMP or other DirectShow players, you'll also need the Shoutcast DS filter from the AACplayer project (http://sourceforge.net/projects/aacplayer/) besides CoreAAC. It provides a DS filter suite and a GUI player for free, but only installs correctly on Win2k and higher.

Anyone has some AAC+ streaming experience or is this not yet possible? Listening to those streams (http://www.tuner2.com/) is possible with several different players besides Winamp now (AACplayer, foobar2000, VLC, GPAC, LAMIP, gmerlin), but broadcasting in aacPlus is only possible with the Orban Opticodec-PC solutions at the moment. If you want to test AAC LC broadcasting at ~80-96 kbps/stereo (or lower in case you prefer it to MP3 at similar bitrates), you can use libfaac.dll in combination with the latest Oddcast DSP plugin (http://www.oddsock.org/tools/oddcastv3/).

Thanks for the reply.

Guess ill go for the software version then.

Listening using aacplayer does not work, windows media player simply wont play it herea also, winamp does.

I want to HE version, the low version is no good.

Too bad there aren't any free encoders, i thought this stuff was open source, guess not :(

MP4Splitter.ax is the file i assume you are talking about, but it crashes windows media player on winxp sp2 (aac player 0.3)

@hans-jürgen (or anyone who knows)

I was wondering if you knew if the orban opticodec is:
AAC+SBR V1 or
AAC+SBR+PS ?

It's AACplus V1....

There is one. Real Producer10 enables to encode in he-aac. It's completely free but very limited.

Hmm its v2, i just found out from the guys that sell it :)

Its not properly put in their website.

Now we seriously need a proper DS AAC+SBR+PS (v1/v2) decoder! :D

Where can i find this "recent" FAAD2 version WITH PS?

Nero does NOT encode PS yet!

Nero does NOT encode PS yet! I had only read about nero's PS support, I was under the impression it was released (I haven't used their encoder in some time) but apparently the discussions I saw were about private betas.

If you search on hydrogenaudio.org you'll find some information about PS and it's support in faad2. It was planned to add PS support including upmixing of all mono streams so that there was a freeware decoder for all nero's files, but perhaps it hasn't been implemented yet either. I haven't been able to find any information on if PS is implemented in faad2 yet, but your best bet is to get the current CVS and try it.

It seems, faad2 DOES decode PS!
I just had a problem with the latest ffdshow NOT to kick in, but now i fixed it (for files)
What did i do:
By pure coincidence i tried playing the files/streams with media player 6.4 (windows standard), it gave me an error, libmmd not in system... google > i found:
http://www.rarewares.org/mp3.html
Intel 8.1 libmmd.dll
Some ICL-compiled files require this library.
Download (749Kb)

I put that file in windows/system32

Latest ffdshow i already had installed
http://celticdruid.no-ip.com/xvid > ffdshow > ffdshow-20050216.exe

In ffdshow installer you can enable AAC or later via:
start / programs / ffdshow > Audio decoder configuration > codecs
by selecting libfaad2.

Now all of a sudden ffdshow kicks in!! (Anyone know why??)
I tried to open my PS sample, and boom, it works (you can hear when PS kicks in)
I got some samples here:
http://www.dial-up.nl/avc_aac_stuff/aac.sbr.ps.samples/

Now all i need is a decent shoutcast DS filter.
AAC PLAYER's just wont do it for me (it crashes, read up), is there other MP4Splitter.ax development?

(CoreAAC can't decode PS yet, needs to be updated!)
