Let’s start with the example of the WebAudio implementation with the Real-Time BPM counter Website. This Website records audio and shows its playback speed,sample rate and output channel detail. To use equalizers and spectograph in WebAudio tool you have to download its extensions respectively. In the website press start. This website is provided as an example by Microsoft EDGE as an sample webpage.

Press start and it will start calculating BPM.

After clicking Start get into inspect section and enable WebAudio tool from the steps provided above. When you click start you will get following output on the right side of the screen showing details about the audio provided.

The output window showing detail about the audio.

You can have different tool for optimizing your audios such as equalizer,spectograms,frequency visualtization.
