Lossless generally means that there is no information loss when converting from cd audio source to digital format, that is, the information density reaches 44khz, like cd 16bit.
brief introduction
High resolution refers to the information density outside the optical disk, such as 96khz and 24bit. Or more.
However, most people can't tell the difference between cd sound quality and more advanced lossy 320k mp3 files. So the upward natural egg.
But genuine hi-res sound source, recording technology and excellent post-production will have better music effect. However, many lossless materials on the Internet are transcribed from unknown sources many times, and many times the information has been lost, so there is indeed a gap, but this gap does not come from the format itself.
