Det finns ingen firma som vet vad den håller på med och det har heller aldrig existerat någon sådan firma och det är oavsett affärsområde
Däremot de som de som startade firman och de som jobbar i firman kan ha god kunskap.
Wiki skrev:Meridian Audio is an English manufacturer of high-performance, high-fidelity audio and video components and systems founded in 1977 by Bob Stuart and Allen Boothroyd.
In 2007 a significant minority shareholding in the company was sold to the Muse Group, a consortium of the Swiss-based luxury goods group Richemont and U.S. film company New Regency.
Muse is now a majority shareholder and is 100 percent owned by Reinet Investments, a sister company of Richemont.
In late 2014, Meridian launched the Master Quality Authenticated (MQA) audio encoding system with the intention of enhancing the quality of digital music experienced via downloaded files or online streaming.
MQA utilises a novel digital sampling technology that is capable of capturing extremely fine timing information accurately, down to the microsecond level, which Meridian claims is not possible with conventional techniques, even at high sample rates. Meridian maintains that current neuroscience indicates such timing accuracy is necessary for truly lifelike recording and reproduction.
When an original master recording is MQA-encoded, this information is "encapsulated" into the bulk of the audio signal by "folding" it in two stages into a standard (typically 24-bit; 44.1 or 48 kHz sampling depending on the sample rate of the original signal) digital coding space but beneath the noise floor. The resulting data is transferred using any lossless audio format such as WAV, FLAC, Apple Lossless etc. As a result, the bandwidth required to stream an MQA file (or the size of a file for download) is significantly less than using conventional techniques, while retaining the full detail of the original master.
On replay via an MQA decoder, the encapsulated detail is recovered, providing an exact representation of the original master recording, and this is confirmed ("authenticated") by the decoding system, generally illuminating an indicator light. If the information is replayed without an MQA decoder, the encapsulated data is ignored and audio quality somewhat better than Compact Disc (16-bit, 44.1 kHz sampling) is experienced.
Initial listener reports appear to be positive. In 2015, Meridian Audio Ltd spun off MQA into its own company, MQA Limited, set up for the purpose in July 2014 and based at the Meridian address in Huntingdon, UK.
Imagination Technologies (IMG.L) and Meridian Audio have entered into an agreement to collaborate on the next generation of multi-channel high resolution wireless audio streaming systems.
https://www.meridian-audio.com/news-events/meridian-news/meridian-audio-and-imagination-announce-collaboration/Jag tycker att det är svårt att veta vad MQA är. Jag har ännu inte sett någon förklaring som framstår såsom begriplig. Det är en oerhört stor svaghet. Man undrar vad de döljer. Då personal och ledning ändras i ett bolag så förändras bolaget mot något nytt med nya vinstintressen.
Vad är Meridian idag? Vad de var igår syns i backspegeln.
