I just checked a local MQA file with Audirvana. Audirvana did not recognize the file as MQA; Audirvana treated the music file as an ordinary 24/48 file.
Then, I renamed the music file from “01 Take It Easy.flac” to “01 Take It Easy.mqa.flac” (this is the name format used when purchasing MQA downloads). Now, Audirvana recognizes this as MQA. Quirky. Yet my less than $10 Android app (USB Audio Player Pro) recognizes either file as MQA.
I wonder if it is the same situation for Studio?
