I'm looking for available AAC Low Delay ( AAC-LD ) encoders in order to build an audio conferencing solution.
Any recommendations ?
Thanks in advance.

I don't know the AAC specs, so I don't know exactly how AAC-LC and AAC-LD differ. It's possible that AAC-LD may not be the best solution for your problem.

Since you want to use a codec for speech and there are low-delay speech codecs available (source code even) it might be a good idea to use one of those (e.g. Speex).

From what I've read about AAC-LD, it combines the benefits of audio quality similar to MP3, with the benefit of minimal delay speech codecs.

Have a look here: http://www.iis.fraunhofer.de/amm/techinf/mpeg4/aac_ld.html

I doubt theres a freely available encoder available to be honest.

New Coding Technologies encoder in winamp 5.3 have some switch, tune for speech, maybe that can be useful

Any new info on this?

Looking for aac-ld encoder to create up and downlink from studido to a location.

I'm not sure what OS you are running on but OS X 10.5 has a new MPEG-4 Low Delay AAC Encoder (it's what iChat uses):

Using windowsXP.....

anayway thanks, it might just be a question of time, hopefully winamp will put AAC-LD into their encoder, so we can use it with shoutcast or oddcast.... (not over the internet but direct connection ISDN

reagards,
