Intro to MQA
I have never witnessed a hi-fi topic with a seemingly self-perpetuating cycle where the more answers given give rise to more questions than the Master Quality Authenticated (MQA) audio codex. At the risk of continuing this cycle, I'm going to begin this review with some MQA facts.
Fidelizer Pro 6.5 is the creation of an audiophile from Thailand by the name of Keetakawee Punpeng. Back in 2011, Keetakawee released freeware for Windows called Fidelizer that provided optimization for dedicated Windows computers working as music servers. His software was designed to improve the sound of music software playing on Windows 7 computers. The software was easy to use and did not make a permanent change to the operating system.
Amarra sQ, a DSP (Digital Signal Processing) engine, is designed to work with streaming services while bypassing Apple's Core Audio. sQ is for Apple OSX only and it costs $29.99. What it delivers is the ability to customize your music's EQ, employ various dither settings, and generally I found that it makes streaming services sound better. What more can you ask for?
How would you like to be able to stream FLAC and AAC files from your NAS, play Internet radio stations, Rdio content, and YouTube videos all from the same app on your iPhone or iPad? How about using the same app to play music through your DLNA compatible network player? Well Creation has an app for you.
Digital room correction. Or should we call it virtual room correction since we're not correcting the room, we're adapting the music's bits during playback to better suit the room. But in order to correct something, you first have to understand what, if anything, needs correcting. Of course you can perform room correction by ear and you very well may come away with a sound that suits your tastes. But to really understand what's going on with the sound in your room, you need to analyze. You need to abstract the musical information into forms that represent various aspects of sound. The Dirac Live Room Correction Suite not only shows you how your music looks, it also shows you how they feel it should look.
