I think we should focus a fixed point version. There should be no need for floating point at all. If fixed point isn't good enough, then we screwed it up. And in case of embedded devices we are seriously limited with floating point and doing that in software just doesn't work out. And this is mostly not directly a performance problem. It is more a power consumption problem. We don't wanna have A2DP drain the battery. Regards Marcel
