1, different mass
HQ is the abbreviation of English High Quality, which means high quality; SQ is English Super Quality, which means super quality, that is, a kind of music that is almost lossless. For those without HQ and SQ logo, it is the standard music type, that is, the quality is average as the saying goes.
2, the amount of information is different
The standard mass belongs to lossy compression. By reducing the audio sampling frequency and bit rate, the output audio file will be smaller than the original file, so the quality of the song is average. There are also high-quality music like HQ and SQ.
3. Different densities
Because of the different information content between SQ and HQ, the number of tracks and the degree of stereoscopic impression of SQ are far stronger than that of HQ. When listening to large-scale compilation, SQ can enhance the sound of subtle hidden instruments and remove noise, which is better than HQ. So the sound density is different and the sound field is different.
4. Different degrees of lack of music.
HQ refers to the songs in high quality mp3 format with 320kbps, and SQ refers to the songs in flac or ape format with lossless music.
5. Different musical experiences
Listening to the same song with special music headphones, SQ music sounds purer, truer and clearer than HQ music.
