HD Voice is Easy to Realize

Last month Daniel Berninger wrote a guest column expressing the benefits of using high definition codec for voice communication. In that post, Dan argues that widespread use of compatible codecs is critical. When we decided to use a wideband codec in EnThinnai, we also faced the problem of compatibility. More importantly, we decided that our users would like to communicate with people who are not yet users of EnThinnai. Our strategy is to dynamically download the codec. I think this simple technique effectively addresses the compatibility issue.
But this means that the codec we use must be freely distributable. This is the reason we decided to use Speex. Last week Skype announced that they will make their codec widely available. I am not sure whether this kind of use is allowed.
