Merdian's MQA


Master Quality Authenticated

Studio Quality Sound You can Stream or Download

Imagine being present at the original studio performance of your favourite recording artist. Every nuance, every subtlety, every tiny drop of emotion delivered to your ears.

This is Master Quality Authenticated, or MQA.

MQA is a revolutionary end-to-end technology that delivers master quality audio in a file that’s small enough to stream or download. What’s more, it’s backwards compatible, so will play on any device. And because it’s fully authenticated, you can be sure you’re hearing exactly what the artist approved in the studio.


MQA delivers studio master quality using no more bandwidth than a CD quality file – so it can be streamed or downloaded.


MQA delivers unsurpassed quality, and is being backed by streaming services, download services, and key music industry players.


MQA authentically reproduces the sound of the studio master, allowing you to step into the magic of the original performance.

The Days of Sacrificing Quality for Convenience are Over

Conventional audio formats discard parts of the sound to keep file size down, but part of this lost detail is the subtle timing information that allows us to build a realistic 3D soundscape in our minds.

Without it, music becomes flattened. And our ears know it isn’t real.

With MQA, we go all the way back to the original master recording and capture the missing timing detail. We then use advanced digital processing to deliver it in a form that’s small enough to download or stream.

The result is astonishing. Every nuance and subtlety of the artist’s performance – every tiny drop of emotion – is authentically reproduced. When you listen, you’ll be transported right into the very moment of creation. You’re there.

MQA is Different

MQA keeps all this timing information, and folds it into a file that’s only a little bigger than a CD. Played back on any existing system, it will sound better than CD. But on an MQA-capable system, the music will be unfolded, reproducing every element that’s in the original recording.
