Flashcards
Hertz (Hz)
Hertz (Hz)
The unit of frequency, which measures the number of sound wave oscillations per second. One Hertz is equal to one cycle per second. Higher frequency means higher pitch.
Dynamic Range
Dynamic Range
The difference between the loudest and the softest sounds in a recording. Dynamic range is important for achieving a balanced audio experience.
Equalisation (EQ)
Equalisation (EQ)
The process of adjusting the balance between different frequencies of a sound signal. This allows you to control the overall sound of your audio.

Study Notes
Audio Communication
- Hertz (Hz): The unit of frequency, measuring the number of 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 corresponds to higher pitch.
- Standard Hertz (Hz) Ranges:
- 20Hz to 20,000Hz: Theoretical human hearing range.
- 80Hz to 4000Hz: Human voice range (higher for females).
- 44,100Hz: CD audio quality.
- Decibels (dB): Measure the amplitude (loudness) of a sound wave. Higher amplitude means louder sound.
- Standard Decibel (dB) Ranges:
- 0dB: Threshold of human hearing (minimum audible sound).
- 96dB: 16-bit audio recording level.
- 144dB: 24-bit audio recording level.
- Dynamic Range: The difference between the loudest and quietest sounds in a recording.
- Tracking: The process of recording audio either from a voice or an instrument.
- Gain, Volume, and Level:
- Gain: Input signal/loudness measured.
- Level: Loudness measured in mixer relative to unity.
- Volume: Output signal loudness.
- Equalization (EQ): Adjusting the balance of different frequencies within an audio signal. Used to increase (boost) or decrease (cut) specific frequencies.
Compression
- Compression: A technique used to control the dynamic range of audio. It reduces the difference between loud and soft sounds.
- Compression Ratio: Describes the amount of reduction in the audio signal for a given increase beyond the threshold. Higher ratios mean more compression.
- Threshold: The level at which the compressor starts to work.
- Attack Time: How quickly the compressor reacts to the sound going above the threshold (milliseconds).
- Release Time: How quickly the compressor stops reacting to the sound going below the threshold (milliseconds).
- Hard Knee: The compressor abruptly changes to reduced volume past a threshold.
- Soft Knee: The compressor gradually reduces volume past the threshold.
Digital Games
- Definition of a Game: Possess "family resemblances"—various components, but with shared characteristics. Games are voluntary; occur in space and time; are uncertain, and are unproductive.
- Winning Condition: Not always necessary. As examples, animal crossing, etc.
- Games as Narratives: Distinction between games and storytelling. Both are different but have elements in common.
- Components of a Game: Material components (physical objects), rules, and player experience.
Audio and Digital Terms (from page 2)
- DAW (Digital Audio Workstation): Software for audio editing.
- MIDI (Musical Instrument Digital Interface): Standard protocol used to connect electronic instruments to a computer.
- AD/DA (Analog-to-Digital/Digital-to-Analog): Processes converting between analog and digital signals.
- ADSR (Attack, Decay, Sustain, Release): Parameters controlling how audio effects react to input.
