Member Function Documentation

filterVector()

std::vector< float > krotos::EnvelopeFollowerSPD::filterVector

(

std::vector< float >

inputMonoVector

)

Processes the incoming sample and returns the envelope follower value. Depends on former incoming sample absolute value.

Parameters

inputSampleCurrent

current incoming Sample

normaliseEnvelope()

std::vector< float > krotos::EnvelopeFollowerSPD::normaliseEnvelope

(

std::vector< float >

inputMonoVector

)

Normalises the envelope vector from min.max to 0-1.

Parameters

inputMonoVector

mono signal envelope vector returns vector<float> with min = 0f and max = 1f

setAttackMs()

void krotos::EnvelopeFollowerSPD::setAttackMs

(

float

attackTimeMs

)

Sets the attack time parameter in miliSeconds and recalculates the coefficient In case only this parameter is updated.

Parameters

attackTimeMs

attackTime in miliseconds

setReleaseMs()

void krotos::EnvelopeFollowerSPD::setReleaseMs

(

float

releaseTimeMs

)

Sets the release time parameter in miliSeconds and recalculates the coefficient In case only this parameter is updated.

Parameters

releaseTimeMs

releaseTimeMs in miliseconds

setupEnvFol()

void krotos::EnvelopeFollowerSPD::setupEnvFol	(	float	attackTimeMs,
		float	releaseTimeMs )

Sets up the attack and release time parameters in miliSeconds and recalculates the coefficients

Parameters

attackTimeMs	attackTime in miliseconds
releaseTimeMs	releaseTimeMs in miliseconds
