Digital Audio Theory

Nyquist Theorem

The samples required to properly represent the audio is 2 times the highest frequency.

What happens when the sample rate is not two times

Imperfections occur, called “aliasing”

Frequency range of human hearing

20Hz-20kHz

How many characters is a 16 bit word/24 Bit Word

16 characters/24 characters

What is Dithering

introducing randomly generated low level noise to fill the bottom bits of a digital “word”

What is Noise Shaping

altering the frequency curve of the dither noise to maximize
effectiveness with the least amount of audible effects.

What is a Work Clock

In digital audio electronics, a word clock or wordclock, or
sampleclock, is a clock signal used to synchronize devices
which interconnect via digital audio signals.
