Methods
(static) adsr()
Create an adsr envelope
- Source:
(static) freqEnv(frequency, octaves, options)
A frequency envelope. Basically the setup to provide an adsr over a number of octaves.
Parameters:
| Name | Type | Description |
|---|---|---|
frequency |
Number | the initial frequency |
octaves |
Number | (Optional) the number of octaves of the envelope (1 by default) |
options |
Object | the same options as an ADSR envelope |

Example
conn(saw(1200), lowpass(freqEnv(440, 2, { release: 1 })))(static) perc(attack, decay, options) → {AudioNode}
Create an attack-decay envelope with fixed duration. It's composed by a linear attack ramp and an exponential decay. This envelope doesn't have release, so it stops after the duration (attack + decay).
Parameters:
| Name | Type | Description |
|---|---|---|
attack |
Number | (Optional) the attack time, defaults to 0.01 |
decay |
Number | (Optional) the decay time, defaults to 0.2 |
options |
Object | (Optional) an options with a context |

Returns:
the signal envelope
- Type
- AudioNode
Example
conn(sine(1000), perc(0.01, 0.5))
conn(sine(1000), perc(null, 1)) // default attack
conn(sine(1000), perc()) // default values
