\"hey there, ive decided to look into these nifty devices as i plan to get more into my home recording n stuff... and i was checking out the frequency response graphs on this site and was wondering how did you make the graph appear... for example did you just play 1 note on the guitar to get that graph? or a chord or a long riff or something? im not quite sure on that part, maybe someone could fill me in, churr\"

    That's from an ap analyzer. That is the speaker compensation response chart/graphic. That is done several ways..either a fixed point or sweep generator or within the programming like the ap we use for other designs.

    Most likely a fixed prec gen on the input and measuring the output with SC on.

    edit- many meas devices have various noise and filter options. A, is that the one SteveK did a while back?

    You usually feed pink noise or a chirp to measure the frequency response of a system. that's what you see there.
