Attack Decay Envelope using AudioGain
Use an AudioGainNode to smoothly raise and lower the volume of a sound.
Roll mouse over the paragraphs below to start and stop sound.
Mode=' . $mode . ", " . $label . "
\n"; } printRollover(1,"linearRampToValueAtTime() for attack and decay"); printRollover(2,"linearRampToValueAtTime() up and down several times, linear down"); printRollover(3,"linearRampToValueAtTime() for attack, exponentialRampToValueAtTime() for decay, setTargetValueAtTime() for release"); printRollover(4,"setTargetValueAtTime() for attack and release"); ?>
Look in the code below to see how the test modes are applied. Example uses "webaudio_tools.js".
