Arta distortion graphs

[davepellegrene]

Is it possible to add the distortion graphs to the fr plot in Arta? I can do it in steps but don't see a way in Arta.
Another Question. Can you view polar plots in Arta?

Thanks
Dave

Easy peasy -

In ARTA, go to Analysis, choose "Frequency Response and distortions"
You will get a dialog box that says:

to use this command

PIR must be used with swept sine
Single channel mode
sequence lenght > 64K
with option: Center peak of impulse reponse


Then you go to Record, and make sure that the Sweep (swept sine)
has those values or check boxes.
Record as usual, and the usual Analysis -> Single Gated will show distortion levels.

Ok, Sequence length was 32K and center peak of impulse response was not checked. Did those. Now I have been using left channel but I don't see anything that you check for single channel mode other then not having dual channel mode checked.

I'll give it a try tonight.
Thanks Dave
