Hi dear,
Do you necessarily need to create it with Canvas?
There are several extensions that can do this.

Description: Using this extension, you can create audio visualisation effects such as Wave , Bar, Hifi, Circle, etc.

I’ve already tried it, but it still doesn’t work. My plan is for a wave to appear when the sensor is actived.

It doesn’t seem like you followed the instructions on how to use the extension.
And I see that this extension is based on an audio source, so it isn’t able to read audio in real time from VUMeter.
Yes, because before I added the latest extension, I already had an extension for the sound sensor. And my plan is to add an innovation in the form of waves, and I have to create another extension. That’s why I followed your suggested extension, but it turned out to be impossible. So, I am still looking for an extension for the sound wave sound sensor.

Forgive me, but at first you didn’t give many details, such as specifying that you wanted a soundwave based on the microphone input, and I assumed you meant an audio file.

However, I haven’t found any extension.
Let’s wait, maybe someone else will succeed.
In the meantime, you could try to find a JavaScript project to use in a WebViewer, like this one.
