Module 1 AUDIO PRODUCTION

MODULE 1:

AI - search engine, autocorrect 

3 types of AI: 

  1. Artificial narrow intelligence (ANI)

  • Personal assistants like Alexa or Siri 

  • Recommendation systems like Netflix or Hulu

  • Self-driving cars 

  1. Artificial general intelligence (AGI)

  • Does not exist 

  • Would possess human-like intelligence 

  1. Artificial superintelligence (ASI)

  • Hypothetical intelligence that surpasses humans 

Examples of text generative systems: Chapt GPT, Claude, Gemini

Example of image generative systems: Dalle, designer, firefly

Example of video generative systems: Sora 

Amplitude: the number of molecules that are moved by a vibration 

Frequency range: 

  • Bass: 10hz - 256hz -> associated with power and fullness

  • Midrange: 256 - 2,050Hz -> most of sound origin (LOWER)

  • 2,050 - 5,000hz -> fundamentals of speech frequencies (UPPER MIDRANGE)

  • Treble: 5,000 - 20,000hz -> sparkle and clarity 

CPS: cycles per second, how frequency is measured 

Dynamic range: difference in the space between quietness and loudness 

Frequency: determined by the length of the waveform and measured from the beginning of one cycle to the beginning of the next (CPS and Hz)

Hertz: CPS is expressed in Hz - 1CPS=1HZ

Human dynamic range: 0db - 140db, 85+ causes damage, 100db avoid, 120db threshold of pain, 140 db ears bleed 

Human hearing frequency range: 20-20,000 hz

Psychographics: groups of people by their likes and interests 

Sound envelope: describes the way the amplitude of the sound varies - Attack, Decay, Sustain, Release 

Sound Level Pressure: amplitude is measured in SPL and expressed in decibels. Sound is measured on a logarithmic scale 

Stinger: short piece of music or sound that makes the beginning of a segment (transition)

3 elements of audio production: voice music, SFX 

Wavelength: the distance between 2 identical parts of a sound wave
