Frequently Asked Questions
How does the Microphone Monitor work?
The tool captures the microphone stream via getUserMedia and routes it through a Web Audio API AnalyserNode. The analyser reads frequency-domain and time-domain data every animation frame to draw real-time level meters and waveform visualizations. An optional direct connection to the audio destination lets you hear your own mic input through speakers or headphones.
Can I hear my own microphone?
Yes. Enable the playback option to route your microphone input directly to your speakers or headphones in real time. Use headphones to avoid feedback loops.
What do the level meter and waveform show?
The level meter shows your microphone's current input volume in real time. The waveform displays the audio signal shape, helping you identify clipping, background noise, or silence.
