Or is there a DRM type code from the studios for each MQA file generated? If so, that sounds like an unwieldy system.
I know as much as everyone else here —which is to say nearly nothing— but I wonder if these security codes are the ones mentioned here on MQA's web site .

The HSM module should optimally sit within the same network as the encoding computers. Its sole job is to hand out signatures for embedding into the file. A remote or cloud-based HSM is possible but performance will be degraded.
Does this mean that the MQA firmware will need to be updated every time a new content provider (label/studio) signs on to provide MQA music?
