hi res

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.
Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtense. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line. A line is either a dark line or a light line. A resolution of 10 lines per millimeter means 5 dark lines alternating with 5 light lines, or 5 line pairs per millimeter (5 LP/mm). Photographic lens and film resolution are most often quoted in line pairs per millimeter.

    Is 24 bit 44.1 kHz as Hi Res?

    Some selections on Qobuz say Hi Res 16, but they play back at 24 bit/44 .1 kHz (not 16/44.1, which I know is CD quality). Is 24 bit/44.1 kHz really hi res? Thanks

In my 20s, the idea that people’s appetite to consume new music regularly would be switched off like some kind of tap was ludicrous. However, now...
