Struct AudioFrame

Single raw uncompressed audio frame.

Namespace: Microsoft.MixedReality.WebRTC
Assembly: Microsoft.MixedReality.WebRTC.dll
Syntax
public struct AudioFrame
Remarks

The use of ref struct is an optimization to avoid heap allocation on each frame while having a nicer-to-use container to pass a frame accross methods.
