K+K Research TAC

TAC demo 5 TAC (Transparent Audio Codec) was developed at K+K research, which comprised two developers: Kevin Anderson (KA) and Karsten Madsen (KM).

This codec became quite famous due to incessant praising about it by KM at several web forums and web pages (one of the most famous is mirrored here. Another one is here. And a third one is here). Among his claims, KM said TAC was better than any codec ever developed (even the FhG AAC encoders, back then the golden standards), best quality at a wide range of bitrates, support and interest from the recoding and gaming industries...

He also announced an AAC encoder (MP01) that supposedly had better quality than Fraunhofer's reference implementation. Still, no one has ever seen it in action.

Eventually KM lost credibility at several forums and disappeared from the scene. Soon afterwards KA (who was the real programmer) gave up developing the format.

In this page are featured two demo encoders with respective frontends. No player is available.

The official web site is available here.
