Decoding in Kodi
I would imagine that in time (may be a lot f time) the Kodi built-in player (PAPlayer) will include a decoder but decoding of this format is currently not generally available and can only be found in a limited amount of software and hardware. probably due to how new MQA still is.
Software Decoding
I am currently enquiring with MQA to obtain a list of all software-based decoders (media players with add-ons for decoding MQA) so that I can configure Kodi to use an external player instead of the internal PAPlayer for all FLAC files in the hopes that I can create seamless unfolding/Decoding of MQA while using Arneson's TIDAL2 Add-on. The output of PCM bit stream would be expanded/unfolded to 96/24 etc. (at least one unfold, maybe eventually more) from Source/Kodi without the need for hardware intervention.
Hello Steve,
I found
MQA Decoding Explained on audiostream.com and
MQA: Questions and Answers on stereophile.com which explain details of the MQA Codec.
If I understand it right, MQA is an Analog-to-Analog reproduction Codec. So the DAC Hardware has to decode the MQA informations to re-create exactly the same Analog Signal as it was Mastered in the Studio. And it can "Authenticate" that it is decodec correctly.
Because every DAC has a different analog signal characteristic to create the Line Output Signal (analog amplifier at the end) the DAC hast to apply device specific filters to the digital values to reproduce the correct audio signal at the end of the amplifier.
I Think, that is the reason that software decoding to 96/24 or 192/24 can only be a kind of "controlled upsampling" and never can reproduce the audio signal to 100%.
So 48/24 or 44.1/24 is the best quality we can get with software decoding in Kodi.
And the most important thing: You have perfect ears to hear any difference between 48/24 and 96/24 or 192/24 !!
(My ears are too bad to detect any difference
)
Please correct me if I'm wrong !
