Study Notes
Introduction to Game Audio
- Game audio encompasses sound design for games and multimedia applications.
- The presentation highlights a historical overview of sound in video games.
Quick History of Sound in Video Games
- Early video games, like Spacewar! (1962), were silent.
- Arcade games (e.g., Pong, Atari, 1972) introduced rudimentary sound to attract players.
- The 1970s saw extremely limited custom hardware in arcade games, with only basic introduction and game-over music during gameplay.
- The 1980s marked the rise of dedicated sound chips (programmable synthesizers or PSGs) and the use of oscillator-based sounds.
- Over time, digital audio workstations (DAWs) began being used to create sound effects.
Home Consoles
- Home consoles began to integrate sound functionalities in the 1970s, with advancements in the 1980s and beyond.
- The number of channels in the audio system varied greatly over time, offering greater complexity in sound design.
16-bit Consoles
- Sega Megadrive (1988) and Super Nintendo (1990) introduced new advancements in sound hardware, like FM and wavetable synthesis.
- These systems benefited from new hardware advances. For example the Yamaha FM Synthesis chip (YM 2612) offered a greater range of more complex sounds.
- Specific sound hardware like the PSG chip (programmable sound generator), often employed multiple channels to enhance sound quality.
FM Synthesis
- FM synthesis was a sound synthesis technique invented by John Chowning.
- It gained popularity in gaming and offered a wider range of timbres and sounds for games.
- Different consoles utilized this technique in their processing capabilities.
16-bit Consoles (Specific Hardware)
- The Super Nintendo Entertainment System and Sony SPC-700 leveraged 16-bit digital signal processing (DSP) combined with wavetable synthesis.
- The capability utilized to play audio waveforms via digital signal processors.
PC + Soundcard
- PCs, in the 1980s and 1990s, featured sound cards that enhanced audio capabilities, such as the Adlib (1987).
- Further advancements in PC hardware led to the introduction of 16-bit stereo PCM and CD-ROM support for integrated audio.
- Other advancements offered more input and output channels for sound.
MIDI
- MIDI (Musical Instrument Digital Interface) was a protocol that enabled communication between digital musical instruments, such as synthesizers and keyboards.
- MIDI data, not sound, was conveyed among instruments.
- MIDI revolutionized games' sound design with better overall quality in sound.
- It played a pivotal role in game music compositions.
- General MIDI (GM) specifications provided standard sounds to ensure consistency across different synthesizers.
MOD
- MOD (a popular sound format) was originally used to produce game music for the Amiga computer.
- It employs small samples for each instrument.
- Similar formats emerged, such as SoundFonts and DLS.
PCM Audio
- PCM (Pulse Code Modulation) evolved, allowing sound cards to play arbitrary sound files.
- Initially, the limitations of bandwidth/storage restricted PCM audio to short sound effects.
- Music was still often handled by MIDI, with audio elements played sequentially over time.
CD-ROM
- Introduction of CD-ROM enabled full music tracks within games in digital sound file formats.
- Music quality in CD-ROM games became similar to studio recordings.
- The use of CD-ROMs made music creation much easier through digitization of music files.
Current Game Engines
- In modern game engines, sounds are imported as PCM files, enabling real-time mixing of effects and music, due to the nature of the interactive gameplay.
3D Games - Positional Audio
- 3D games enhanced realism by incorporating positional audio, enabling players to hear sounds based on the position of game objects relative to their character's position.
- The advancement introduced new techniques in processing, giving depth and variation to the game sound effects.
3D Games - Realism
- Advanced 3D games also simulated characteristics like room size (acoustic properties) and surround sound, for improved immersion and realism.
- This heightened depth and impact on the sound.
- Specific technologies like HRTF are important for virtual reality (VR) simulations.
Algorithm Music
- Several game series successfully integrated algorithm music, using methods like iMusic for generative music, providing distinct approaches to sound in video games.
Interactivity
- Games require real-time sound mixing due to their dynamic nature compared to static media.
- Dynamic audio in interactive content (games) is crucial.
Examples of Game Sounds
- Various sound categories (music, sound effects, dialogue) contribute to the overall experience within games.
Classification of Sounds - Diegetic vs. Non-Diegetic
- Diegetic sounds originate from sources within the game world (e.g., character footsteps).
- Non-diegetic sounds come from outside the game world (e.g., music from a narrator).
Classification of Sounds - Dynamic vs. Static
- Dynamic audio changes based on game events; static audio remains constant (e.g., constant background music).
Classification of Sounds - Ambient
- Ambient sounds create the atmosphere in a game world, creating a variety of sounds for virtual environments.
Classification of Sounds: 2D vs. 3D
- 2D audio in game engines typically does not change with positional changes.
- 3D audio in games dynamically updates based on the player's location, changing volume and location (pan) of sounds in 3D space.
Classification of Sounds: Constant vs. One-Shot
- Constant sounds are continuous loops, and are present in many video games and multimedia experiences.
- One-shot sounds are triggered based on game events.
3D Game: Ambient Sounds (Types)
- Area Loop - encompasses large areas of a map, with attenuation by distance and direction
- Source Loop - spatialized at a specific location.
- Source One-Shot - events occur rarely, can coincide with certain parts of the map.
Asset List
- The asset list comprises a catalog of all sounds within a game. This list usually includes filename, type, brief description, whether it's looping or one-shot, trigger, and location.
- It ensures efficiency in managing and using various game sound effects and other audio elements.
- Specific data is essential for the design process for many game creators.
