Audacity Forum

Maybe the conversion is seeing the "other" zero value and interpreting as maximum output instead? I would have to dig back through my source code and notes from the 90's, but if memory serves there are two zeroes in this signed 8-bit system: 0x00 and 0x80. That looks like what's going on in the capt...

It is a nice presentation, but in fact I AM dealing with an "old" "simplest" DAC, as the video (7m50s) suggests (zero order hold). "Not wrong, just really confusing". Even in the video he mentions that the stair steps are not at the very OUTPUT ("not a finished conversion"). And I don't believe I sa...

Hi, Thanks for the reply. I understand this can't be changed in Audacity. For the record, the DAC in my pro audio hardware sampler works exactly like that. It requires a reconstruction LPF filter at the output to remove the stepping. (Info: http://en.wikipedia.org/wiki/Digital-to-analog_converter in...

Hi, Well assuming you are looking at the output of a DAC (lets say DC coupled and the data latched -- which is common and what I'm working on), the stepping I showed is exactly what you would see. Of course later on there would be a reconstruction LPF or something. However, what Audacity is doing is...

Hi, I'm doing some file comparison between audio on a PC and a hardware DAC playing the same data. It would be great if I could zoom in to the individual sample level and see the data as the steps they are, rather than the (interpolated) ramps that audacity draws. Is there any way to turn off the ra...
