Hello, there are microphone level controls inside of the application, where you can adjust the input levels of the built in microphone or an external microphone. They are located under the sidebar menu, under the "Mic" option.
If you are using an external microphone, you may also need to make audio adjustments on that device as well.
If you are currently using our solution at an invent, you can also contact our 24/7 live support using the contact below:
