Quoting Koen Vos <koen.vos@skype.net>: > For typical VoIP applications, Moore's law has lessened the pressure > to reduce bitrates, delay and complexity, and has shifted the focus to > fidelity instead. I think this is a typo, and you mean "lessened the pressure to reduce bitrates and complexity, and has shifted the focus to fidelity and delay instead". > All in all I'm happy with the current requirements document, and it's > unclear what specific changes (besides a Bluetooth mode) you have in > mind...? Me too; I'd also like some clarification as to whether we're talking about (a) existing Bluetooth headsets or (b) future hardware designed to support the IWAC. If (b), then this is just a matter of negotiating the acceptable encode+decode complexity, for eventual implementation by DSP or ASIC. If (a) ... I'm surprised that such a retrofit is even conceivable. If it is in fact possible, I would very much appreciate instructions on how to experiment with new codecs on existing headsets. Once we know how to build test rigs, we can see what the complexity requirement there is. If we can't test it, I don't think we can target it. --Ben
