struct MaterialA type that describes the acoustic characteristics of a surface. An audio material defines how a surface absorbs and scatters sound energy across frequency bands. Use preset materials for common real-world surfaces, or create custom materials from raw absorption and scattering coefficients. ```swift // Use a preset material: let walls: Audio.Material = .concrete // Create a custom material: let custom = Audio.Material( absorption: .init([0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10]), scattering: .init([0.10, 0.09, 0.08, 0.07, 0.06, 0.05, 0.04, 0.03, 0.02, 0.01]) ) // Modify a preset material: let thickCarpet: Audio.Material = .carpet.scalingAbsorption { frequency in frequency > 1000 ? 0.5 : .zero } ```
absorption(data: Audio_Absorption): Audio_Materialfunc absorption(_ data: Audio.Absorption) -> Audio.MaterialCreates a new audio material with the provided absorption data. Example usage: let material: Audio.Material = .concrete.absorption([500: 0.3, 1000: 0.4, 4000: 0.5])
scattering(data: Audio_Scattering): Audio_Materialfunc scattering(_ data: Audio.Scattering) -> Audio.MaterialCreates a new audio material with the provided scattering data. Example usage: let material: Audio.Material = .wood.scattering([500: 0.3, 1000: 0.4, 4000: 0.5])
