getSound().audio?

Is editing the properties of getSound().audio allowed according to the guidelines?

Keeping in mind not repeatedly playing sounds in the draw function, is changing the volume and pitch allowed?

I made this function to play sounds at different pitches and volumes:

var advSound = function(name, volume, preservesPitch, playbackRate, startTime) {
    var sound = getSound(name);
    if(!sound){
        return;
    }
    sound.audio.preservesPitch = preservesPitch;
    sound.audio.playbackRate = playbackRate;
    
    sound.audio.volume = constrain(volume, 0.01, 1) || 1;
    sound.audio.currentTime = startTime || 0;
    sound.audio.play();
};

Is this allowed by the guidelines? If not why?

(I'll delete the program if it's not allowed. I have no desire to be banned.)
