Detailed Description

class daisysp::AdEnv;

Author: shensley

Todo:

• Add Cycling

• Implement Curve (its only linear for now).

• Maybe make this an ADsr_ that has AD/AR/Asr_ modes.

Trigger-able envelope with adjustable min/max, and independent per-segment time control.

Public Functions Documentation

function AdEnv

inline AdEnv()

---

function ~AdEnv

inline ~AdEnv()

---

function Init

void Init(
    float sample_rate
)

Parameters:

• sample_rate sample rate of the audio engine being run

Initializes the ad envelope.

Defaults:

• current segment = idle
• curve = linear
• phase = 0
• min = 0
• max = 1

---

function Process

float Process()

Return: the current envelope value.

Processes the current sample of the envelope. This should be called once per sample period.

---

function Trigger

inline void Trigger()

Starts or retriggers the envelope.

---

function SetTime

inline void SetTime(
    uint8_t seg,
    float time
)

Sets the length of time (in seconds) for a specific segment.

---

function SetCurve

inline void SetCurve(
    float scalar
)

Sets the amount of curve applied. A positve value will create a log curve. Input range: -100 to 100. (or more)

---

function SetMin

inline void SetMin(
    float min
)

Sets the minimum value of the envelope output. Input range: -FLTmax_, to FLTmax_

---

function SetMax

inline void SetMax(
    float max
)

Sets the maximum value of the envelope output. Input range: -FLTmax_, to FLTmax_

---

function GetValue

inline float GetValue() const

Returns the current output value without processing the next sample

---

function GetCurrentSegment

inline uint8_t GetCurrentSegment()

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

---

function IsRunning

inline bool IsRunning() const

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