That’s it.
You should be done. The way that I knew that things were NOT initially set
correctly on my machine was that I was getting VERY DIFFERENT SPL traces from
20-­‐20,000 Hz depending on “length” setting the sweep was set for. THAT SHOULD
NOT HAPPEN!!! Setting the length to higher settings extends the length of time for
the sweep and collects more data points/frequency (which would theoretically
make the data more accurate at the expense of computation time to perform the
Fourier transform) but it should not “demonstrably” affect the overall SPL trace.
Good luck!
