1

Sample rate

snap shots across time

2

Bit depth

headroom

3

How do sample rate relate to digital audio?

quality and intelligibility

4

Sample rate measured in

Hz

5

Common sample rates

44.1, 48, 88.2, 96, 192

6

Nyquist says

we need at least double the frequency

7

human hearing

20-20k

8

oversampling prevents

aliasing (artifacts)

9

quantization

resolution of audio (resolution) - more headroom!

10

Common bit depths

16, 24, 32-bit float

11

condensor

2 polarized plates (electromagnetic)

12

dynamic

has a coil (electrostatic)

13

ribbon

thin corrogated metal diaphraghm (electrostatic)

14

tube mic

2 plates polarized with vacuum tube

15

normal flow

no extra patches

16

half normal

normal until you make a patch then it cuts out the signal

17

fully isolated

must patch everything

18

difference between 24 bits and 16 bits?

24 has 144dB of headroom, 16 has 96, so 48dB more at 24
