About MQA
MQA stands for Master Quality Authenticated.
Using pioneering scientific research into how people hear, MQA's award-winning technology
captures and authenticates the sound of the original master recording, and packages it for
efficient streaming and storage.
When playing MQA streams, "MQA", "MQA." or "OFS" will be displayed on screen.
"MQA": A regular MQA file is guaranteed to match the source material when played back on
a device with an MQA decoder.
"MQA.": An MQA Studio file is the same – but has also been approved in the studio by the
artist or producer, or verified by the copyright owner.
"OFS": A valid state of MQA indication for when a device receives an MQA signal already
decoded by a downstream piece of hardware or software.
