"Codec" literally means compression-decompression. A codec is the part of
the application which digitizes the speech at one end (compression) and
changes it back to analog sound on the other end (decompression). Just how
well any particular codec works depends on a myriad of factors: the
available bandwidth, the state of collisions and congestion on the internet
itself, etc etc.

With CU, and ECU, you are given your choice of codec's to choose under
Edit/Preferences/Audio. Once chosen, you alter the quality and reliability
of your audio connection.

Similarly, there are video codec's which do the analogous magic with the
video signal.

Hope this helps,
