Improving VoIP Audio Quality
With the increase in the VoIP technology, more and more people are heading towards the use of VoIP technology to make overseas calls as these calls become almost free of cost on VoIP. Millions of people are now using the VoIP services to make audio calls around the world.
The only issue, now-a-days, is the audio quality of the calls made. The audio quality is sometimes ok while at other times it is a bit poorer and this call quality must be corrected so that the people are able to substitute the costly conventional telephony calls with the VoIP audio calls.
The VoIP user may be hardware based or the software based. Actually, the VoIP technology uses the software to communicate. A mic plus headphones or speakers are the only hardware requirements while the software requirement include the program such as Skype (with above 100 million users), etc. which is free of cost. Some other people also use Instant Messaging (IM) clients like Google Talk or MSN Messenger.
Previously, VoIP poor quality audio was a common thing among the people of the globe. There are various reasons for this and the voice quality may be improved by correcting those problems.
1. Never use cheap or low cost mic and headphone as they have poor quality receivers and mics. Purchase high quality mic plus headphone so that to make a better audio call.
2. Close the rest of the programs on your computer and make sure that the RAM of your computer is free to be used by the audio call that you are currently making. The program Babble.net occupies a large portion of Ram, therefore, just close the other programs for the time being and concentrate on the audio call that you are making.
3. Check the speed of internet; If it is slow then contact the internet service provider for the solution of the problem. The bandwidth you are using must have, at least, 512 K downloading while 128K uploading speed. If you are using WiFi, then it might be a matter of positioning only.
4. Don’t run multiple applications simultaneously and if the problem persists, you may increase the RAM of the computer; this will surely make some difference as far as the audio voice quality is concerned.
5. The best latency is 200ms or less. Consult your VoIP service provider and let it be corrected if the latency goes above it.
6. Sometimes an echo of his own voice is heard by the person who is speaking through the microphone. This echo may be minimized by using a separate mic plus headphone for the purpose.
Thus, there are many methods through which you can improve the sound quality of the audio call that you are making now.
