Detailed Description

template<int DownsamplingFactor>
class hise::DownsampledSmoother< DownsamplingFactor >

A lowpass filter that can be used to smooth parameter changes.

Constructor & Destructor Documentation

DownsampledSmoother ( )

inline

Creates a new smoother.

If you use this manually, you have to call prepareToPlay() and setSmoothingTime() before using it.

Member Function Documentation

float getSmoothingTime ( ) const

inline

Returns the smoothing time in seconds.

void prepareToPlay ( double  sampleRate_ )

inline

Sets the internal sample rate.

Call this method before setting the smooth time.

void setDefaultValue ( float  value )

inline

Sets the internal value to the given number.

Use this to prevent clicks for the first smoothing operation (default is 0.0)

void setSmoothingTime ( float  newSmoothTime )

inline

Sets the smoothing time in seconds.

If you pass 0.0 as parameter, the smoother gets deactivated and saves precious CPU cycles.

float smooth ( float  newValue )

inline

smooth the next sample.
