Audio mastered for analog formats also has a lot of limitations.

Examine the vinyl record for example. Audio is encoded through grooves on a physical surface which is then read by a needle travelling at a constant speed.

Firstly, the physical size of the needle limits what you can decode. You can't have peaks or valleys that are too close to each other, otherwise the needle will just skip over them. You also can't have transitions that are too steep.

Digital actually makes everything closer to "intended" sounds, because you can eliminate so many physical and mechanical factors.
