VoIP Audio Device Recommendations
When using VoIP for your Webinar, audio quality can vary based on your audio software/hardware manufacturer as well as your operating system.

To select and test your Mic & Speakers settings
Right-click the
system tray icon and select Preferences.Select Audio.
|
Mac users can select audio devices in-session only. GoToWebinar will automatically detect the input and output devices connected to your computer.
To select and test your Mic & Speakers settings
You can test your audio devices through the Audio pane of the Control Panel. If your audio devices are connected correctly, you will see the sound meters in the Control Panel light up green.
If the meters for Mic or Speakers do not light up green when you or others are speaking, click the icons in the Audio pane of the Control Panel. A drop-down menu will appear when you click either icon.
Microphone: To test, speak into your microphone; if it is connected correctly, the sound meter will light up green. If the green meter does not light up, select another device listed in the drop-down menu and repeat this test.
Speakers: It is recommended that you test your speakers. To test, select each device from the drop-down menu until you will see the sound meter light up green and hear others speaking in the conference. If the green meter does not light up, select another device listed in the drop-down menu and repeat this test.
Avoiding Call Echo
A USB headset is recommended (see VoIP Audio Device Recommendations).
Built-in or external speakers can cause echo. We recommend reducing the speaker volume to a low level.
Webcams with microphones can pick up additional noise and cause echo. Using a Webcam for your audio is not recommended.
Laptops with built-in microphones: Built-in microphones can pick up noise and cause echo. Using a built-in microphone for your audio is not recommended. If you know how to turn off your laptop’s built-in microphone, turn it off for your presentation (check your laptop’s owner manual).
Echo from an attendee: If you suspect echo from an attendee, check who is talking at the bottom of the Audio pane and mute that attendee or ask the attendee to lower his or her speaker volume.
If you join your meeting via telephone make sure the audio setting in your control panel is not set to User Mic & Speaker.
Reduce background noise (see next section).
See also VoIP Organizer Tips and Best Practices in this section.
Avoiding Background Noise
A Webinar is best presented from a quiet location.
If using a microphone, move the microphone closer to your voice and away from competing sounds (i.e.,: computer fans).
Avoid moving or touching the microphone during your presentation.
A good quality headset is recommended. Webcams and built-in microphones can pick up noise and are not recommended.
Dropped Words, Delay, Robotic Sound
Dropped words, delay or robotic sound is often due to poor network performance, lack of memory or high CPU usage.
Close all applications you are not using for your presentation.
A dial-up Internet connection can cause poor performance. For optimum performance when using VoIP, we recommend a broadband Internet connection. (See System Requirements.)
Start Broadcast
GoToWebinar Audio Service: If you are using GoToWebinar’s audio service, you must click Start Broadcast in the Organizer Control Panel or *1 on your telephone keypad to start the conference.
Check Sound Device Settings
Are the correct sound devices selected in the GoToMeeting/GoToWebinar Preferences menu? See VoIP Audio Setup in this section.
If using a microphone: Does your microphone have a physical mute/unmute button on it? Check that your microphone is not muted.
If an attendee can’t hear you, his or her speaker volume may be off or set too low.
Analog microphones are sometimes too quiet; we recommend using a USB headset or USB desktop microphone instead.
If you are using a desktop microphone, avoid touching the microphone since it may cause a reduction in the volume of your voice.
Speaking very loudly can affect the volume; try speaking at a lower level.
Internet Connection
The speed of your Internet connection can affect one-way sound. For optimum performance when using VoIP, we recommend a broadband Internet connection. See System Requirements.
File Sharing
Uploading a file while using GoToWebinar can sometimes affect VoIP sound quality. It is recommended that you close all file sharing applications before you start your Webinar.
Streaming music or video while using GoToWebinar can sometimes affect VoIP sound quality. It is recommended that you close all streaming music or video before you start your Webinar.
VoIP Organizer Tips and Best Practices
Pre-Webinar
As with any Webinar, it is important to test your sound quality and audio settings before your live event. In addition to testing your audio settings, it is recommended to start your Webinar in Practice mode with other organizers or panelists to provide feedback on your voice quality.
If you plan to record your Webinar, be sure to test the recording feature while in Practice mode.
In-Session
It is a best practice to keep attendees muted during your presentation and unmute individual attendees as necessary.
Attendees who join the audio portion of your Webinar are joined muted by default. Up to 25 attendees can be unmuted at any one time (this is a combination of VoIP and phone attendees)
Manage Attendee Audio Attendee, joined via VoIP, muted (default) (a) Attendee, joined via telephone, muted (default) (b) Attendee joined via telephone, un-muted (c) Attendees who join the Webinar via telephone must enter their Audio PIN so that you have full audio controls through the Organizer Control Panel. If not entered, you can right-click the person’s name and select Send Audio PIN. This will send a pop-up message with the Audio PIN to that person (d) |

An audio device (speakers or headset) is necessary to join a Webinar using VoIP. When an audio device such as microphone or speakers is not detected, some of the following errors may occur:
• Virtual Operating System (VMware, Parallels, etc.)
An error message will appear if speakers (or headset) are not present or are not connected properly, or if there is no sound card installed in your computer. You will not hear audio at this time and will not be heard in the conference.
Check that your speakers (or headset) are properly connected and click Try Again in the Audio pane of the Control Panel. See VoIP Audio Setup – PC or VoIP Audio Setup – Mac.
If you have the option to join the Webinar via telephone, you will automatically be switched to Telephone mode. Dial in to the conference using the number and Audio PIN provided in the Audio pane of your Control Panel.
After the first minute of a session, GoToWebinar looks for microphone input from attendees who are using a microphone, have speaking rights and are un-muted.
If no input is detected, you may get a Trying to speak? error message. This error may appear under the following conditions:
You have not spoken or made any sound during the first minute of joining the Webinar, or
The microphone device was incorrectly selected. You can click the Audio Setup link if you are trying to speak but can’t be heard. See VoIP Audio Setup – PC or VoIP Audio Setup – Mac.
An error message will appear if a microphone (or headset) is not present or is not connected properly. You will still be able to hear the Webinar but will not be able to speak.
Check that your microphone (or headset) is properly plugged in.
If you have the option to join the Webinar via telephone, you can switch to Telephone mode. Then dial in to the conference using the number and Audio PIN provided in the Audio pane of your Control Panel.
An error message will appear if your microphone fails or is unplugged after joining a Webinar. When this happens, you will no longer hear audio nor be heard by others.
Check that your microphone is properly plugged in. If it is, test your microphone device and click Try Again in the Audio pane of the Control Panel. See VoIP Audio Setup – PC or VoIP Audio Setup – Mac.
If you have the option to join the Webinar via telephone, you can switch to Telephone mode. Then dial in to the conference using the number and Audio PIN provided in the Audio pane of your Control Panel.
Virtual Operating System (VMware, Parallels, etc.)
An error message will appear if you are attempting to join a Webinar using VoIP through a virtualized operating system, such as VMware, Parallels, etc. In this instance, to connect to audio, please choose one of the following:
Rejoin the Webinar through a non-virtual operating system.
If you have the option to join the Webinar via telephone, you can switch to Telephone mode. Then dial in to the conference using the number and Audio PIN provided in the Audio pane of your Control Panel
