Le Spectrogram

This app needs microphone access to visualize your voice. Click Start to begin.

This is a simple spectrogram utility created by kd8lvt for LesageSinging on YouTube. It allows you to visualise the qualities of your voice, for learning purposes.

How do I use it?

Click the "Start" button above, and allow usage of your microphone.

Does my microphone data get sent anywhere?

Only if you supply a valid session password. If you do, your data will be sent directly to your session host.

Otherwise, all your data stays entirely on your device. Feel free to snoop around the client code using your browser's dev tools :)

What spectrogram library does this use?
