Bug in Imported frequency response section 11 years 10 months ago #3883

Hi,

I have loaded the following file-
20.0 -0.0
100.0 -1.0
110.0 10.0
120.0 -5.0
200.0 0.0
9000.0 -8.0
10000.0 -10.0
and in the PEQ setting screen the data is graphed incorrectly.
the 200.0 Hz point is on the graph at 275 Hz. Point the mouse at it and the orange box says 275Hz, the blue box says 200Hz.
Also the 10Khz point is missing.
Previously I tried a file with integers and that produced even stranger results. The sample in the help doesn't have integers, but it might be good to mention in the help to only use floats.

Im going to add a feature request too - it would be great on the PEQ graph screen to have a button which when pressed adds the PEQ response with the imported freq response. (I realise this may need some interpretation when the input and output PEQs are used).

The plugin is the 2.1 way advanced plugin downloaded today.

@ John,

We can have a closer look later on..

Blue is the imported so that's the value you should be reading (not orange which is the PEQ data). Seems like on my side I'm seeing the correct data (i.e. read the blue point, imported freq and it's showing 200Hz). Float is indeed required as the typical .frd file format. We can add it to the user manual indeed.

Have a look at the attached screenshot. The blue line hits the 0db mark at just under 288Hz instead of 200Hz. The Blue box says 200Hz but points to the same spot well to the right of the 200Hz vertical line on the graph.
Note also that the 9000.0Hz point in the .txt file appears close to the 20K mark on the graph, and the 10000.0Hz point is not on the graph (perhaps off the end).
These seems to be some frequency stretching going on.

Indeed, something seems odd here. I wonder if it's related to the limited number of samples.. (i.e. not realistic application). We can get our software guys to investigate later on this week.
