Revision as of 00:38, 30 April 2020 by SpatialPlays (talk | contribs) (Added arguments table and "See also" sections)
Sound.init synthesizes a sound from various parameters, including look-up tables
that represent one cycle of the waveform and the volume envelope.
Arguments
| Parameter Name | Type | Default Value | Meaning |
|---|---|---|---|
| duration | number | 1 | length of the sound in seconds |
| frequency | number | 440 | number of repeats of the waveform per second |
| envelope | [number] | [1] | volume (0 to 1) over the duration of the sound |
| waveform | [number] | [-1, 1] | wave value over an audio cycle |
Usage Notes
Call this on a new Sound object, or to reset a previous one.
Example
pew = new Sound
pew.init 0.3, [8000,100], [1,0]
pew.play
Example 2:
hitSnd = new Sound
hitSnd.init 1, 100, [1,0], Sound.noiseWave
hitSnd.play
