There are many factors as to why the audio quality in your conference sounds bad. One of the main culprits of bad audio is bad microphones. Almost all built-in microphones on laptops have bad sound quality. They pick up the presenter’s voice and also all the ambient sound of the room that the speaker is in. We highly recommend presenters using PC headset microphones for better sound quality.
If users are experiencing what sounds like scrambled audio or robotic voices, there is a data bandwidth issue happening. Depending on everyone’s Internet connection to the conference and who actually is listening, there will be different audio experiences heard.
Any users on wireless Internet will also hear scrambled or robotic audio due to interference and a small amount of bandwidth capable of being shared. If someone is presenting, we highly recommend they present from a hard line connected to the respective PC.
To save on audio bandwidth, try asking presenters to place their microphones on “push-to-talk” which is an option offered to users once they are invited to speak. Using push-to-talk turns the data transmission on and off saving everyone bandwidth when audio is not transmitting.
I hope one of these solutions helps with your audio quality issue.
