Member Function Documentation

active()

virtual bool active ( )

inlinevirtualinherited

determines if the effect is active

clip()

int16_t clip ( int32_t  in, int16_t  clipLimit = 32767, int16_t  resultLimit = 32767  )

inlineprotectedinherited

generic clipping method

clone()

Boost * clone ( )

inlinevirtual

Implements AudioEffect.

copyParent()

void copyParent ( AudioEffect *  copy )

inlineprotectedinherited

id()

int id ( )

inlineinherited

Allows to identify an effect.

process()

effect_t process ( effect_t  in )

inlinevirtual

calculates the effect output from the input

Implements AudioEffect.

setActive()

virtual void setActive ( bool  value )

inlinevirtualinherited

sets the effect active/inactive

setId()

void setId ( int  id )

inlineinherited

Allows to identify an effect.

setVolume()

bool setVolume ( float  volume )

inlineoverridevirtual

define the actual volume in the range of 0.0f to 1.0f (values > 1.0f boost the signal, capped to q1_14_t's ~1.99994 range when PREFER_FIXEDPOINT is active)

Reimplemented from VolumeSupport.

volume()

virtual float volume ( )

inlinevirtualinherited

provides the actual volume in the range of 0.0f to 1.0f

Reimplemented in I2SCodecStream, VS1053Stream, USBAudioDeviceBase, AudioPlayer, and VolumeStream.
