”Further confusing the matter is the fact that there appear to be two types of MQA file: MQA and MQA Studio.
In actuality, there’s not much difference between the two; the distinction is there merely to indicate the “provenance” of the file: a regular MQA file (denoted by a green indicator or display text) is guaranteed to match the source material when played back on a device with an MQA decoder; an MQA Studio file (denoted by a blue indicator or display text) is the same – but has also been approved in the studio by the artist or producer, or verified by the copyright owner.
So in that way, MQA Studio could be seen as the “director’s cut” of musical recordings.”
