Bandwidth comparisons by codec

Calling all codec geeks! 

Ever wondered what the difference in true bandwidth requirements, latency, and so on is between G.729a 8k and G.711 48k (for example)?  Check out the bandwidth calculator to find out. It provides full details on latency, bandwidth requirements, packets per second and so on.

Cool!

It will be good if you can add other codecs like iLBC, iSAC and Speex. This will demonstrate that by trading processing power for bandwidth. one can have better quality voice. Thanks.
