Mute microphone in speakers but still be able to analyze (createAnalyser) with Web Audio Api?

Question

Im trying to create an Analyser node to get the signal from a microphone, and be able to create a graphic with the received input. But I dont want to the speakers to still recive the microphone signal.

Source (microphone) -> Analyser -> Destination(?)

The destination is always the speakers... Can I put the destination to a void or similar, and be able to still analyze the microphone?

I tried to play with the Volumne (gain node) but that affects the analyser in the end.

In summary: I need to be able to analyze an input from the microphone but mute that signal on the speakers.

EDIT: Here is what I'm doing.

analyser = context.createAnalyser();
analyser.smoothingTimeConstant = 0.4;
analyser.fftSize = 64;

microphone.connect(analyser)
analyser.connect(context.destination);

This is working fine... but Im getting the sound on the speakers. If I ask for example:

var data = new Uint8Array(analyzer.frequencyBinCount);
analyzer.getByteFrequencyData(data)

Then data will contain the reponse from microphone.

But if I add gain after like this

volume.gain.value = 0; 
microphone.connect(analyser)
analyser.connect(volume);
volume.connect(context.destination);

or I do not make the connect to context.destination, then the data array will be all 0 (not reponse from microphone)

Answer 1

Actually, you don't even need to connect the analyser. It should process without being connected to the destination.

Answer 2

Add a gain node after the analyser node and set its value to 0. So..

var volume = context.createGain();
volume.gain.value = 0;

microphone.connect(analyser);
analyser.connect(volume);
volume.connect(context.destination);
