Constructors

  Type Name Description
Public function  

FSilenceDetection ( float InOnsetThreshold,
float InReleaseThreshold,
int32 AttackDurationInSamples,
int32 ReleaseDurationInSamples
)

 InOnsetThreshold is the minimum amplitude of a signal before we begin outputting audio, in linear gain.

Functions

  Type Name Description
Public function float Returns the current estimate of the current amplitude of the input signal, in linear gain.
Public function int32

ProcessBuffer ( const float* InAudio,
float* OutAudio,
int32 NumSamples
)

 Buffers InAudio and renders any non-silent audio to OutAudio.
Public function void

SetThreshold ( float InThreshold
)

 Set the threshold of audibility, in terms of linear gain.
