Compaact!

Compaact! was an AAC encoder launched in 2003. It offered an impressive feature set, and was shown in testing by Roberto Amorim to be competitive at 128kbps with both the FAAC and Coding Technologies (Real) encoders. Compaact! featured both the LC and Main Object Types, CBR, VBR, Multichannel, high resolution (24bit/96kHz) encoding, and command line support.

As of 2005, Compaact! development has been discontinued.
