looking for encoders...

Hi

I'm looking for encoders for the following profiles/object types:

MPEG-2 AAC LC
MPEG-4 AAC LC
MPEG-4 AAC LTP
MPEG-4 AAC scalable (not Scalable Sample Rate)

So far, I've found this info

Nero Digital Audio - encodes to MPEG-4 AAC LC, HE, and HEv2
FAAC - encodes to MPEG-4 AAC LC (?)
Compaact - encodes to MPEG-4 AAC LC & MAIN , MPEG-2 AAC LC & MAIN

Anybody know where I can find the MPEG4 AAC LTP and scalable encoders?


Thank you

Look at Really Rare Wares. Psytel, MBsoft and Homeboy are very early implementations of AAC, and I remember having a lot of compatibility issues with them - Maybe something you are looking for 
Can't wait for a HD-AAC encoder :P

i second RRW.

what compatibility issues did you have with psytel, odyssey?

Just incompatibility across encoders/decoders, which I assume are because of the many different formats. That's why I think some of them may be of his interrest

Thanks for the input.  I'm basically looking for a reference encoder and decoder to test against another decoder.  The idea is to take reference wave files, encode them in certain MPEG-4 object types/ MPEG-2 profiles, then decode them using a reference decoder. 

I have a slight update to my post due to recent findings:

MPEG-2 AAC LC - Encode/Decode using FAAC 1.25 (force MPEG-2 option)/FAAD2 2.5
MPEG-4 AAC LC - Encode/Decode using FAAC 1.25/FAAD2 2.5
MPEG-4 AAC LTP - Encode/Decode using FAAC 1.25/FAAD2 2.5
MPEG-4 AAC Scalable - Encode using AACPlay.exe, Decode using ??

I would like to be able to encode/decode the Scalable files using FAAC & FAAD2 instead of relying on the older AACPlay encoder so I only use one encoder/decoder combo.  Anyone know of any encoder/decoder that does AAC scalabe?
