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.

Member Function Documentation

GetCurrentSegment()

uint8_t daisysp::AdEnv::GetCurrentSegment ( )

inline

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

GetValue()

float daisysp::AdEnv::GetValue ( ) const

inline

Returns the current output value without processing the next sample

Init()

void 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

IsRunning()

bool daisysp::AdEnv::IsRunning ( ) const

inline

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

Process()

float AdEnv::Process

(

)

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

Returns

the current envelope value.

SetCurve()

void daisysp::AdEnv::SetCurve ( float scalar )

inline

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

SetMax()

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

inline

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

SetMin()

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

inline

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

SetTime()

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

inline

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

Trigger()

void daisysp::AdEnv::Trigger ( )

inline

Starts or retriggers the envelope.
