How to stop AudioStreamMicrophone from outputting to speakers?

Question

I’m trying to write a program where I process the input audio from my microphone. I’ve added an extra audio bus with an AudioEffectCapture and I seem to be capturing the data.

The problem is, Godot only seems to capture audio to the AudioEffectCapture’s ring buffer if I have AutoPlay checked on the AudioStreamPlayer. This has the side effect of echoing everything the microphone hears to speakers. I don’t want that - I want to just capture the audio data without playing it.

Can I somehow configure my setup so that the AudioStreamMicrophone captures the data without playing it at the same time?

Try audio effect record instead of capture

My other suggestion is just muting the bus, but idk if the mute is before or after the capture effect.

Muting the Capture channel seems to work.

Using Record won’t work since it is used for recording short clips rather than letting you access the raw data as it’s generated.
