Interfaces
AudioProcessor |
Interface for audio processors, which take audio data as input and transform it, potentially modifying its channel count, encoding and/or sample rate.
|
AudioProcessorChain |
Provides a chain of audio processors, which are used for any user-defined processing and applying playback parameters (if supported).
|
DefaultGainProvider.FadeProvider |
Represents a time unit-agnostic fade shape to be applied over an automation.
|
GainProcessor.GainProvider |
Interface that provides sample-level gain automation to be applied on an audio stream.
|
SpeedProvider |
A custom interface that determines the speed for media at specific timestamps.
