MQA Decoding Explained – Audio Stream
If you play back a 24-bit/192kHz MQA-encoded file using iTunes through a regular DAC (i.e. a non-MQA DAC), you will get a 24/48 file.
If you play back a 24-bit/192kHz MQA-encoded file through an MQA software decoder like Tidal HiFi, Audirvana, or (soon) Roon, and you are using a regular DAC (i.e. a non-MQA DAC), you will get a 24/96 file. A software decoder does not offer the ability to ‘unfold’ the original file to resolutions higher than 24/96 (or 24/88.2).
If you play back a 24-bit/192kHz MQA-encoded file through an MQA-enabled DAC, you will get a 24-bit/192kHz file. If you are also using a software decoder like Tidal HiFi, Audirvana, or (soon) Roon, you can have the software decoder perform the first ‘unfold’.
One thing to note: if the original MQA file is 24/48, 24/96, or 24/88.2, it will pass through the software decoder and be ‘unfolded’ to its original resolution.
結局MQAの再生には……まぁいいや。
どのみち私にはストリーミングでしか縁がなさそうだし。
とりあえず、Roonのアレは間違いなくTIDAL Mastersの音源だったということだな。
そしてLINNやらLUMINやらの「TIDAL対応プレーヤー」の扱いはどうなるのだろう？
