Comment: It would be nice if the MQA decoding function became compatible with 360 Reality Audio (MPEG-H 3DAUDIO). USB-DACs with MQA decoding are common, but it would be nice if TVs, motherboards and graphics boards could have MQA decoding as a standard feature.

1 High quality sound: Digital sound with less sound blur - Time axis resolution (sound blur) is equivalent to human sensitivity to time (10μsec or less) → Playback sound naturally expresses the sound at the time of recording. This means that the reproduced sound naturally represents the sound as it was recorded. In the past, digital sound had pre-echoes and post-echoes, which were blurred before and after the sound.  ＊MQAの音のにじみはCDの1/400  
2 High-resolution with small file size: Less bulky storage capacity and support for streaming ・For digital distribution, the file size is small, so the download time is short and communication costs can be reduced. In the case of digital distribution, the small file size reduces download time and communication costs. Home audio devices do not require large storage capacity, and can hold more content than high-resolution sound files. High-resolution sound files can be used with streaming services, which are expected to expand in the future.

  

＜During encoding, the data is folded and stored in an area that does not affect the original data. During decoding (playback), the folded data is opened and played back. It is characterized by the fact that it is not "compressed" but "folded.

3 File Compatibility and "High-Resolution on CD" MQA-CD: Compatibility with existing playback environments. Even if you don't have an MQA decoder, you can still play back high-resolution sound files in the existing format. Even without the MQA decoder, the sound file can be played as an existing format sound file, and even in this case, it can be enjoyed as a sound source with less sound blur. In this case, the sound file can be played back as an existing CD player. It can also be ripped. Ripping is also possible. (MQA sound source even after ripping).
