Audio Mapping

Terminology

• Frequency

• Amplitude

• Spectrum

• Spectrogram

• Waveform - less useful for pixelmapping?

Modules

• spectrum bars
  • bars that increase in length depending on amplitude
  • x = frequency, y = amplitude
  • or vice versa
  • one-sided or middle-out
• spectrum graphs?
  • like bars, but bar is full length and intensity with amplitude changes instead?
• spectrogram (involves time)
  • like spectrum graph, but dots instead of bars and dots move / feedback over time
  • could also be pulses, aka one frequency across that pulses down time

Unified Version (does not include waveform)

Could be one module that has two sets of variables:

• X Position / Size
• Y Position / Size
• Intensity
• Color?

matched with

• Frequency
• Amplitude
• Time

"Preset" Template:

Matrix	Frequency	Amplitude	Time
tx	0-1 = 0-1	0-1 = 0-1	0101
sx	0-1 = 0-1	0-1 = 0-1	0101
ty	0-1 = 0-1	0-1 = 0-1	0101
sy	0-1 = 0-1	0-1 = 0-1	0101
in	0-1 = 0-1	0-1 = 0-1	0101
re	0-1 = 0-1	0-1 = 0-1	0101
gr	0-1 = 0-1	0-1 = 0-1	0101
bl	0-1 = 0-1	0-1 = 0-1	0101
