Microphone Audio Level using WebRTC

[Roma...@gaz.kherson.ua]

While initializing audio connection in Flash client we have sequence:

      1. WebRTC connection (checking if I can hear myself) and, If answering "No"

      2. connecting with Flash

When connecting with Flash we are able to control and change microphone gain, but If connecting via WebRTC - control is absent.

My question is - is there any option to enable microphone gain  control while connecting via WebRTC?

By now it's necessary to go to audio settings to Control panel to change this value or via Sound mixer.

It takes a lot of time and very inconvenient.

Thanks in advance!

Hi Romanenko,

Originally, the WebRTC APIs didn't let you control the microphone gain, so the join sequence for WebRTC was just "can you hear yourself talking".

However, WebRTC provides auto-levelling of gain, so you don't need to have users adjust.  FireFox and Chrome work slightly differently (they each have their own implementation of WebRTC), so we recommend that users try both.

Are you encountering cases where the auto levelling in WebRTC isn't working for your users?

We have mixed client configuration in our video conference.
On one side we have lot of people (no posibility to equip each person with notebook) and technically one notebook with video projector, connected via HDMI (video and audio out transferred to projector). External (USB) webcamera used to show speaking person. Build in microphone is used for audio input (it has comparely nice sensitivity).
On te other side, we have few notebooks on remote sites connected in VPN network, with simple headsets.

On remote places - autoleveling work fine, but on central place we have large room and some kind of unusual audio configuration.
And autoleveling is not working well... Sometimes manual level setting is highly wanted...

Hi Romanenko,

We've noticed that when using WebRTC audio, FireFox and Chrome behave slightly differently with regards to auto-leveling.  Also, recommend you try a professional USB microphone, such as

In an area setting, this microphone does a very good job of picking up audio of the presenter (much better than a built-in microphone which has a shorter range).
