Hi
I am a little behind in the latest technology in the music streamer, what is Dirac, MQA or BluOS? if it takes too long to explain point me to a site that summaries everything. Thanks.
Dirac (or Dirac Live) is a digital signal processing software to measure your space (frequency/phase response) using a recommended calibrated USB microphone and then allows the user to make adjustments. A freeware alternative, REW (Room EQ Wizard) is more flexible but harder to use.
MQA (Master Quality Authenticated) is a Meridian (high-end audio company from the UK) sponsored digital format to "squeeze" high resolution formats into Redbook (CD format) using re-mastered versions of original recordings. Mostly found in Tidal (a CD quality subscription service with millions of songs in it's library), it requires compatible hardware to fully use it but can run through any CD quality system. It's benefits continue to be debated and most hardware vendors have not signed on.
BluOS is a proprietary operating system for accessing stored or streamed digital musical libraries developed by NAD and used in their label products and (originally) their BlueSound spin off brand of gear.
