Computational models can synthesize natural ambient sounds like footsteps and thunder

Evidence

‘Natural sources’ refers here to non-musical and non-speech sources, such as sounds of walking in different terrains, the sound of a falling tree, thunder, and so on. Such synthesis methods have applications in computer games and other virtual environments. Different statistical and other methods are used to synthesize such sounds (Cook, 2007; Farnell, 2010). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 694

Categorization

• DEFINE: Defines ‘natural sources’ as a synthesis category distinct from music and speech.
• SEED: An angle on procedural audio for virtual environments — how sound design in games leans on physics-based synthesis rather than sample playback.
• corroborated: 2 independent passages support this claim — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 694
