QUOTE (KMD @ Feb 22 2012, 07:57)  The digital waveform in the first picture is a plot of the samples. It is a correct plot of the samples . Not quite. It is a plot of the samples with straight lines drawn between them, something no DAC would ever do. |

I used audacity a few years ago and as I remember the lines switch off at the sample resolution magnification. I wonder what software the original "plots" came from. |
