Sound.envelope
Revision as of 07:04, 28 April 2020 by SpatialPlays (talk | contribs) (Adds a link to the audio generated by the example script)
Sound.envelope controls the volume over the duration of the sound. It can be set a value or list of values between 0 and 1, 0 being silent and 1 being the maximum volume possible.
Examples
This script creates a strange sci-fi sound effect that gradually changes volume over time: Link to Audio Generated
scifi = new Sound
duration = 5
freqList = [ noteFreq(72), noteFreq(72), noteFreq(72), noteFreq(84), noteFreq(84), noteFreq(84), noteFreq(80), noteFreq(80), noteFreq(80), noteFreq(80), noteFreq(79), noteFreq(79), noteFreq(77) ]
envelopeList = [ 0.0, 0.5, 0.25, 0.75, 1.0, 0.8, 0.75, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2 ]
