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.

2⁰	=1	monochrome, often black and white
2¹	=2
2²	=4
2³	=8	Most early color Unix workstations, VGA at low resolution, Super VGA, AGA http://en.wikipedia.org/wiki/Web_colors#Web-safe_colors
2⁴	=16
2⁵	=32
2⁶	=64
2⁷	=128
2⁸	=256
2⁹	=512
2¹⁰	=1024
2 ¹¹	=2048
2¹²	=4096
2¹³	=8192
2¹⁴	=16384
2¹⁵	=32768
2¹⁶	=65536	"thousands of colors" on Macintosh
2²⁰	=1048576
2²⁴	=16777216	Truecolor or "millions of colors" on Macintosh systems
2³²	= 4,294,967,295	refers to 24-bit color (Truecolor) with an additional 8 bits
2⁶⁴	= 18,446,744,073,709,551,616	= 16 exabytes. That's more than 18 billion billion bytes.

-===One's Compliment===
-One's Compliment uses regulgar binary numbers to represent positive numbers. To make that numer negative you just filp all the bits from 1 to 0 or 0 to 1.

-11111011
-To figure out the sign of the answer we mustcheck the MSB (most significant bit).If MSB is 0 number is positive, intepretnormally If MSB is 1 number is negative
-    * complement all bits
-    * add 1
-    * interpret as negative number
-==Sampling theory==
-sampling process
-Bit Depth
-over 24 bit 	used mainly for internal processing and really high end audio equipment
-bit 	Professional recording and internal processing
-bit 	CD quality audio (not so good for processing)
-bit 	Smaller size used for consumer voice stuff and multimedia
-==Sampling Rates==
-kHz 	Professional recording and new fancy sound cards
-kHz 	Professional recording (New CD/DVD format)
-kHz 	Professional recording (found mainly on DAT recorders used for film)
-.1 kHz 	CD quality Audio
-kHz 	Multimedia/ Games
-kHz 	Multimedia/ Games
-File Size per Sampling rate and Bit Depth
-Sample Rate 	Bit Width 	File Size per minute
-kHz 	24-bit Stereo 	33.0 MB
-.1 kHz 	16-bit Stereo 	10.5 MB
-.1 kHz 	16-bit Mono 	5.3 MB
-.1 kHz 	8-bit Stereo 	5.3 MB
-.1 kHz 	8-bit Mono 	2.6 MB
-kHz 	16-bit Stereo 	5.3 MB
-kHz 	16-bit Mono 	2.6 MB
-kHz 	8-bit Stereo 	2.6 MB
-kHz 	8-bit Mono 	1.3 MB
-kHz 	16-bit Stereo 	2.6 MB
-kHz 	16-bit Mono 	1.3 MB
-kHz 	8-bit Stereo 	1.3 MB
-kHz 	8-bit Mono 	660 KB
-Note : Dropping the Sampling Rate or Bit Depth by half leads to half the file size
-File formats
-name 	ext. 	info
-aiff 	.aif 	audio interchange file format (mac native) supports markers and regions
-sd2 	.sd2 	sound designer 2 (digidesign native) supports markers and regions
-wave 	.wav 	wave file (Microsoft) many different formats most support markerz and regions
-au-law 	.au or .aul 	au-law file (unix native) supports compression
-RAM 	.ram or .ra 	Real audio File supports compression and streaming
-Mpeg3 	.mp3 	Mpeg layer 3 supports vairble compression and streaming (AMP)
-AAC 	.aac 	Mpeg2 Advanced Audio Coding AC-3 standard NEW not supported yet
-http://www.execpc.com/%7Ereal/aac/index.html
-MIDI 	.mid 	not and audio format
-Modular (MOD) 	.mod 	kinda an audio format (used mainly for games)
-ASF wmv 	.asf .wmv 	windows Media and Advanced Streaming Format Microsoft supports variable compression streaming video encryption
-CD Formats
-RedBook Audio standard CD audio format
-CDROM-XA (eXtended Archetecture) audio and data
