Study Notes
Audio Communication
- Hertz (Hz) is a unit of frequency, measuring cycles per second. One Hz equals one cycle per second.
- Frequency refers to the number of times a sound wave oscillates per second, measured in Hz. Higher frequency equals a higher pitch.
- Standard human hearing range is 20Hz to 20,000Hz. The human voice range is 80Hz to 4,000Hz (higher for females). CD quality audio is 44,100Hz.
- Decibels (dB) measure sound wave amplitude (loudness). Higher amplitude equals louder volume.
- 0dB is the threshold of human hearing.
- 96dB is a common 16-bit recording level.
- 144dB is associated with a 24-bit recording level.
- Dynamic range is the difference between the softest and loudest sounds in a recording.
- Gain is the input signal loudness, controlled by the interface.
- Level refers to the loudness in a mixer relative to unity gain
- Volume is the output signal loudness.
- Equalization (EQ) adjusts the balance of frequency components in an audio signal. This allows boosting or cutting specific frequencies.
Compression
- Compression controls sound dynamic range by reducing the difference between loud and soft sounds.
- Compression needs to start working at a threshold level.
- The compression ratio indicates how much the output changes for each dB above the threshold.
- A ratio of 1:1 means no compression.
- A ratio of 2:1 means 1dB of output for every 2dB of input above the threshold.
- "Hard Knee" compression kicks in sharply once the threshold is reached.
- "Soft Knee" compression gradually increases as the input level goes above the threshold.
- Attack time is how quickly the compressor reduces the input signal above the threshold.
- Release time is how quickly the compressor returns to normal once the signal falls below the threshold.
Digital Audio Terms
- DAW: Digital Audio Workstation
- MIDI: Musical Instrument Digital Interface
- AD/DA: Analog to Digital/Digital to Analog conversion
- ADSR: Attack, Decay, Sustain, Release (describes the envelope of audio signals)
Digital Games
- Games share family resemblances.
- "A game is voluntary activity, separate in time and space, uncertain, unproductive, governed by rules, contains make-believe." (Roger Caillois)
- Digital games can or can not have a clear win condition. Animal Crossing doesn't have a clear objective, while Tetris does.
- Games have components: material, objects, systems, rules, player experience.
