It’s interesting to compare the quality that can be obtained using digital audio with legacy media such as the vinyl disk and magnetic tape.
Noise shaping performs an important role in digital audio because it allows hardware to be made at lower cost without sacrificing performance, and in some cases allowing a performance improvement.
Oversampling is a topic that is central to digital audio and has almost become universal, but what does it mean?
Digital audio relies completely on sampling and no treatment of the subject can be complete without looking at how it works.
Digital audio has a remarkably short history, but apart from a few enthusiasts of legacy technology, the takeover has been total.
It seems almost superfluous today to specify that audio is digital because most audio capture, production and distribution today is done numerically. This was not always the case and at one time audio was primarily done without the help of numbers and the term digital audio was introduced to distinguish the new technology from what went before.
