Public Functions Documentation

function Adsr

inline Adsr()

---

function ~Adsr

inline ~Adsr()

---

function Init

void Init(
    float sample_rate,
    int blockSize =1
)

Parameters:

• sample_rate - The sample rate of the audio engine being run.

Initializes the Adsr module.

---

function Retrigger

void Retrigger(
    bool hard
)

Parameters:

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

\function Retrigger forces the envelope back to attack phase

---

function Process

float Process(
    bool gate
)

Parameters:

• gate - trigger the envelope, hold it to sustain

Processes one sample through the filter and returns one sample.

---

function SetTime

void SetTime(
    int seg,
    float time
)

Sets time Set time per segment in seconds

---

function SetAttackTime

void SetAttackTime(
    float timeInS,
    float shape =0.0f
)

---

function SetDecayTime

void SetDecayTime(
    float timeInS
)

---

function SetReleaseTime

void SetReleaseTime(
    float timeInS
)

---

function SetSustainLevel

inline void SetSustainLevel(
    float sus_level
)

Parameters:

• sus_level - sets sustain level, 0...1.0

Sustain level

---

function GetCurrentSegment

inline uint8_t GetCurrentSegment()

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

get the current envelope segment

---

function IsRunning

inline bool IsRunning() const

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

Tells whether envelope is active
