When you organize a webinar and have to deliver information through voice or video, you want to make sure that all participants get the crispest audio quality possible of your voice and have as clear a view as possible of yourself or the images and videos you want to show.

Webinars and web conferences today use VoIP technology, which takes advantage of the underlying network infrastructure of the Internet to carry the voice and video data packets to and from the correspondents.

This makes communication free in many cases, and cheap otherwise, much cheaper than what it would cost with the good old telephone system. This also allows for a lot of additional features and power that enhance and enrich the communication experience. Here’s what you can do to optimize your webinar.

What You Can’t Control

While there are many things you can do to achieve this, there are also a number of factors that can affect your voice and video quality that are beyond your control. You can deliver good stuff, but if on the receiving end your recipients have poor quality hardware, poor bandwidth and inefficient software, the quality they receive will definitely suffer. So make sure you specify the necessary requirements for prospective participants in case you doubt adequate equipment and requirements.

Get the Right Hardware

Invest on some good hardware that will wrap your voice in the clearest envelope.
Don’t speak in a webinar using your smartphone or cell phone, unless in dire situations, like you are exclusively reporting as a special envoy. The microphone in the portable device has fuzzy sounds and inconsistent volume levels, and makes you subject to battery autonomy limitations and possible dropouts.
Also avoid using speakerphones, which will pick up a lot of background noises.

Use a headset or special microphone that plugs in your computer and uses your sound card. Also invest on a headset or microphone that is of high quality, like one with echo cancellation, noise reduction and optimized for VoIP communication. If you have an in-house voice system through which you are using your existing telephone set or an IP phone, you can use it for voice delivery, as it offers good voice transmission.

If you are including video, you will want to deliver high quality, although it is not yet the default standard. It is not complicated. Invest on a high quality HD web cam and deliver high quality video. Of course you need to have sufficient bandwidth, and only those recipients who have sufficient bandwidth and have hardware appropriate for HD video will receive the HD. If you do this, choose software that allows your users to switch to low quality as an alternative to squarely being denied the video.

Get the Right Service

A webinar service is one that hosts everything behind the curtains and makes everything possible on the technical side. Take time to choose and select the right service for you.
After the important criteria of budget, features, number of participants etc., consider the other technical factors. Get an expert to advise you if need be. For instance, you might want to know and be advised on which codecs and which protocols are used for voice and video transmission. Here is a list of some webinar tools you can choose from.

Have Sufficient Bandwidth

None of the other factors will improve your webinar if you don’t have adequate bandwidth. It is best to have a high bandwidth ADSL line. This is the main factor affecting voice and video quality in modern telephony.

Set Your Environment

The place where you will be for the webinar needs to have an environment conducive to it. You don’t want your participants to hear your dog barking, your child shouting or the toilet being flushed in the background. Don’t allow anyone or anything to disturb you, and get rid of your mobile phone for the duration of the webinar, so as to eliminate interferences, of both technical and personal types. If you are showing yourself in video, make sure you are in a well lit environment, as lack of luminosity affects the quality of a picture and of video.
