Frequently asked questions

What is the difference between AES50 and SuperMAC?

AES50 is an open standard created and owned by the Audio Engineering Society (AES50, AES standard for digital audio engineering - High-resolution multi-channel audio interconnection (HRMAI). Published by Audio Engineering Society, Inc. Copyright ©2005 by the Audio Engineering Society, New York, NY., USA. www.aes.org). Copies of the AES50 standard are available from the AES website.

SuperMAC is a proprietary technology that provided the basis for the AES50 standard. Originally developed by Sony Pro-Audio Lab in Oxford, England, it is now owned by Klark Teknik. The Audio Engineering Society does not operate a certification scheme for its standards and therefore cannot endorse any proprietary implementations of them (even if an AES standard is based on them), and therefore the owner of a proprietary implementation can only make a claim of compliance with an AES standard. This is the reason for Klark Teknik identifying SuperMAC as being AES50-Compliant.
