a better example, 2 sensors placed at different seats and using EoT as the test signal
usual vibsensor style view against time, suggests it is a bit noisy (wasn't especially careful with securing the sensor tbh) but seems sane
now looking at the frequency response, using the summed vibration to keep the graph simple & comparing the two seats. They look pretty similar except one seat falls away at the low end
pick one as the reference so we can really concentrate on the differences, now we can really see that one seat is feeling it much more than the other and this seat is the one that is closer to the sub. This suggests a need for more subs to produce a more even response across the area & also illustrates how quickly TR falls away as the sub gets further away.
next add the source track as a target curve (means get the track as a wav and drag it onto the target screen)
you can now add this to the analysis screen, for now you have to manually adjust the level so in this case I set it so the curves meet at the 30Hz tone. We can already see my room adds a random spike at ~40Hz that is non existent in the content and in fact this is my room mode so we can see how a room mode adds TR as well
(NB: the glitch over on the right appears to be some sort of rendering bug on chrome on linux, doesn't happen on windows)
finally set EoT as the reference series so we can see how we track the source, this makes it clear how much one seat is hotter than the other and the extent to which we're falling behind the curve.
