如何调制 Web Audio API Square OscillatorNode 的脉宽? [英] How to modulate the pulsewidth of the Web Audio API Square OscillatorNode?

问题描述

我想通过连接到其他 OscillatorNode 来调制 Web Audio API OscillatorNode 的方波.但是我在 AudioParams 中找不到参数.

I want to modulate the square waveform of the Web Audio API OscillatorNode by connecting to other OscillatorNodes. But I can not find the parameter in the AudioParams.

这是可能的还是有解决方法?

Is this possible at all or is there a workaround?

我想过使用audioContext.createWaveTable()"函数创建一个自定义"波表振荡器.该波表可以包含具有扫描脉冲宽度的不同脉冲.

I thought about creating a "custom" wavetable Oscillator with the "audioContext.createWaveTable()" function. This wavetable could contain different pulses with sweeping pulsewidths.

但我不知道如何通过 AudioParams 控制波表指针的位置来调制扫描.

But than again I have no idea how to control the position of the wavetable pointer via AudioParams to modulate the sweep.

这是可能的还是我对这个 API 的工作原理有根本的误解?

Is this possible or do I have a fundamental misunderstanding how this API works?

推荐答案

恐怕不行.我们的振荡器中还没有脉宽调制.您必须在脚本处理器节点中手动完成.

You can't, I'm afraid. We don't have pulse-width modulation in the oscillator yet. You'll have to do it by hand in a script processor node.
