What is VoIP Codec?

A codec refers to an algorithm that is used to decode and encode voice conversation in VOIP. The sound and voice that human beings hear is in analogue form and has to be converted to digital to make it possible to transmit it over the internet. The sound or voice has to be converted back to analogue once it reaches the receiving end so that it can be heard.

There are various ways that the decoding and encoding can be done but the majority of them use compression. This method ensures that the bandwidths are reduced. If the compression is heavy, there is usually a delay in the conversation because it takes time. It is possible to find a VoIP codec that will take a minimum amount of time.
