Detailed Description

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

Todo

• Add Cycling

• Implement Curve (its only linear for now).

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

Public Functions Documentation

function AdEnv

inline daisysp::AdEnv::AdEnv () 

---

function GetCurrentSegment

inline uint8_t daisysp::AdEnv::GetCurrentSegment () 

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

---

function GetValue

inline float daisysp::AdEnv::GetValue () const

Returns the current output value without processing the next sample

---

function Init

void daisysp::AdEnv::Init (
    float sample_rate
) 

Initializes the ad envelope.

Defaults: * current segment = idle * curve = linear * phase = 0 * min = 0 * max = 1

Parameters:

• sample_rate sample rate of the audio engine being run

---

function IsRunning

inline bool daisysp::AdEnv::IsRunning () const

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

---

function Process

float daisysp::AdEnv::Process () 

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

Returns:

the current envelope value.

---

function SetCurve

inline void daisysp::AdEnv::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 SetMax

inline void daisysp::AdEnv::SetMax (
    float max
) 

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

---

function SetMin

inline void daisysp::AdEnv::SetMin (
    float min
) 

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

---

function SetTime

inline void daisysp::AdEnv::SetTime (
    uint8_t seg,
    float time
) 

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

---

function Trigger

inline void daisysp::AdEnv::Trigger () 

Starts or retriggers the envelope.

---

function ~AdEnv

inline daisysp::AdEnv::~AdEnv ()
