I also think this is the weakest spot in the argumentation of the paper. While in theory with Nyquist I can reconstruct the waveform with the lower bound of samples (i.e. 2x frequency) perfectly, I need infinite sums for it - so speaking in algorithms: I cannot compute it in reasonable time. So what is done in DACs is to approximate the original waveform with as much sums as possible in a given timeframe. Let's say for proper playback I can do 100calculations (take whatever number you like) in 1ms. Based on 100 calculations: can I get a better approximation of the original waveform if I have 100 samples or 200 samples ? Reading Wikipedia articles about Nyquist doesn't give me an answer for that. But that's the central question that needs to be answered, not if Nyquist in theory can reproduce a waveform with a given number of samples. -- bluegaspode Did you know: *'SqueezePlayer' (www.squeezeplayer.com)* will stream all your music to your Android device.
