Coinciding with the announcement, the Japan Audio Society (JAS) also released a statement certifying MQair with the "Hi-Res AUDIO WIRELESS" logo.

High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
MQA is a three part process applied to digital audio music recordings consisting of: 1) modifying and controlling the end to end digital filter response; 2) preparing the high-quality audio for transfer to a smartphone or audio device using a lossy audio compression format; and 3) decompressing the recording for playback.

The Super Audio CD (SACD) format was created by Sony and Philips, who were also the developers of the earlier standard audio CD format. SACD uses Direct Stream Digital (DSD) based on delta-sigma modulation. Using this technique, the audio data is stored as a sequence of fixed amplitude (i.e. 1-bit) values at a sample rate of 2.884 MHz, which is ...

A Super Audio CD uses two layers and the standardized focal length of conventional CD players to enable both types of player to read the data. Objective lenses in conventional CD players have a longer working distance, or focal length, than lenses designed for SACD players. In SACD-capable DVD, Blu-ray and Ultra HD Blu-ray players, the red DVD ...
An audio format is a medium for sound recording and reproduction. The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data. Note on the use of analog ...
An extreme example, Todd Rundgren's Initiation LP, with 36 minutes of music on one side, has a "technical note" at the bottom of the inner sleeve: "if the sound does not seem loud enough on your system, try re-recording the music onto tape." The total of around 40–45 minutes often influences the arrangement of tracks, with the preferred ...
