Member Function Documentation

GetCurrentSegment()

uint8_t daisysp::Adsr::GetCurrentSegment ( )

inline

get the current envelope segment

Returns

the segment of the envelope that the phase is currently located in.

Init()

void Adsr::Init	(	float	sample_rate,
		int	blockSize = 1 )

Initializes the Adsr module.

Parameters

sample_rate

- The sample rate of the audio engine being run.

IsRunning()

bool daisysp::Adsr::IsRunning ( ) const

inline

Tells whether envelope is active

Returns

true if the envelope is currently in any stage apart from idle.

Process()

float Adsr::Process

(

bool

gate

)

Processes one sample through the filter and returns one sample.

Parameters

gate	- trigger the envelope, hold it to sustain

Retrigger()

void Adsr::Retrigger

(

bool

hard

)

\function Retrigger forces the envelope back to attack phase

Parameters

hard	resets the history to zero, results in a click.

SetSustainLevel()

void daisysp::Adsr::SetSustainLevel ( float sus_level )

inline

Sustain level

Parameters

sus_level

- sets sustain level, 0...1.0

SetTime()

void Adsr::SetTime	(	int	seg,
		float	time )

Sets time Set time per segment in seconds
