LFO不會影響biquadfilter頻率

Question

我可以使用振盪器來調製另一個振盪器頻率或增益節點增益值......但是當我連接到biquadfilter頻率參數時，沒有任何變化。這是一個錯誤？

let ctx = new AudioContext() 

let o = ctx.createOscillator() 
let oGain = ctx.createGain() 

let lfo = ctx.createOscillator() 
lfo.type = 'sin' 
lfo.frequency.value = 5 

let lfoGain = ctx.createGain() 

let hipass = ctx.createBiquadFilter() 
hipass.type = 'highpass' 
hipass.frequency.value = 3000 

o.connect(oGain) 

lfoGain.gain.value = 25 

oGain.connect(hipass) 

hipass.connect(ctx.destination) 

o.type = 'square' 

lfo.connect(lfoGain) 
lfoGain.connect(hipass.frequency) // does nothing? 
lfoGain.connect(o.frequency) // works 

o.start() 
lfo.start()

好吧，我需要對我的LFO一路走高gain價值聽到的區別。將其從25更改爲1000我可以聽到它。
