A chief inherent feature of MQA is security and authentication. Very little of this side of the "product" is talked about or acknowledged by the "inventor". The files cannot be copied for example to serve as a backup should the original get corrupted. You don't "own" the copy after purchasing it. You merely purchased the right to playback the file. The codec is proprietary and guarded as if it were (actually is) the mechanism that ensures complete control of distribution and pricing in the marketplace. It is a means of guaranteeing that all copies of the copyright protected material in the marketplace come from and fall under the full control of one source. Effectively, it is nothing like the open source standard we now have with respect to PCM digital audio. If you are an electronics company that wishes to build products that handle MQA, you have to secure a licensing agreement with MQA.
