How Digital Audio works

[ThinkSta]

Huh?

Are you talking about the power supplies to the converters or something?

[Robert]

Nope. When an Analogue to digital conversion takes place, it's better to use sample and hold - rather than continuously changing the voltage. AD conversion does require a steady voltage - hence sample and hold is used. When the sample as finished, the voltage is dropped - but with sample and hold, when it finishes the sample - it smooths the voltage over rather than dropping it

The stair step is a bad analogy to how digital audio works and leads to lots of confusion.

Please watch this video, everything is repeatable and a list of resources to try it yourself are given.
