Answer 1

是的。查看StereoPannerNode来自 Web Audio API .

The pan property takes a unitless value between -1 (full left pan) and 1 (full right pan). This interface was introduced as a much simpler way to apply a simple panning effect than having to use a full PannerNode.

另请参阅此示例:https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Using_Web_Audio_API#Adding_stereo_panning_to_our_app :

const pannerOptions = { pan: 0 };
const panner = new StereoPannerNode(audioContext, pannerOptions);

<input type="range" id="panner" min="-1" max="1" value="0" step="0.01">

const pannerControl = document.querySelector('#panner');

pannerControl.addEventListener('input', function() {
    panner.pan.value = this.value;
}, false);

track.connect(gainNode).connect(panner).connect(audioContext.destination);

(注意:这不是 Vue 特有的)
