What is the difference between a sound effect (SFX) and background music (BGM) in 2D games?
Answer: SFX are short one-shot clips triggered by events; BGM is a looping track for ambiance
Sound effects are brief audio cues triggered by in-game events, while background music loops continuously to set the scene's emotional tone.
What audio format is most commonly used for looping music in HTML5/WebGL 2D games?
Answer: MP3 or OGG Vorbis
MP3 and OGG Vorbis are compressed formats widely supported by browsers and game engines, balancing file size with audio quality for streaming BGM.
What is 'audio pooling' in 2D game development?
Answer: Reusing a fixed set of audio source objects to play sounds without constantly creating new ones
Audio pooling pre-allocates a set of audio sources that are recycled for playing sounds, avoiding the garbage collection cost of instantiating new sources each time.
What is 'spatialized audio' or '2D positional audio'?
Answer: Adjusting volume and panning based on the sound source's position relative to the listener
Positional audio changes volume (distance-based falloff) and stereo panning so that sounds appear to come from specific locations in the game world.
What is 'audio falloff' in 2D games?
Answer: The reduction of sound volume as the listener moves farther from the source
Audio falloff (attenuation) reduces sound volume with increasing distance from the source, simulating how real-world sound travels.
What is a 'music transition' technique used for in 2D games?
Answer: Smoothly changing between music tracks using crossfade or stingers to match gameplay state
Music transitions (crossfades, layering, or stingers) switch BGM tracks seamlessly when game state changes, such as entering combat or completing a level.
