## Digital Theory

Word of the Day Analog How stuff works - How Analog and Digital Recording Works

Analog vs. Digital the arguments in a nutshell

Analog Digital Good
Infinite dynamic quantization (infinite resolution) Quantization error fix - more bit depth/oversampling
Good? - The warming effects 'we're used' to from tape compression. Good?-'Perfect' reproduction of high frequencies - 'soundz harsh fix - 'using warm-sounding mikes and preamps (tubes)'
Bad - Tape noise and generation loss Good - 'no generation loss'
Bad - 'Cheap recordings sound cheap' Good - 'cheap recordings sound good but digital'

* 'anything in quotes is what I like to call an opinion

## Binary Numbers

As Humans we use a 10 base numbering system. For machines this numbering system is impractical.

Gottfried Willheml von Leibnitz devised the binary number system in 1679

Converting Binary Numbers

Binary->Decimal

```   110102 = (1 * 24) + (1 * 23) + (0 * 22) + (1 * 21) + (0 * 20) = 1610 + 810 +  0 + 210 + 0 = 2610
```

Dividing by two

integer remainder binary #
26
26/2 0 0
13/2 1 1 0
6/2 0 0 1 0
3/2 1 1 0 1 0
1/2 1 1 1 0 1 0
0/2 that's it kids

Base2

Each new bit doubles the number of intervals.

That's more than 18 billion billion bytes.
