windowing
Attempting to set window in Fuzzmeasure for semi anechoic response. Using the impulse graph, I'm looking for that first echo, but not sure where it is. I zoom into the vertical, but it's still not obvious to me. Any tips? I'm generally measuring speaker systems at 1 meter.
I’m confused

Inappropriate?You might want to try the log squared impulse response view to find this echo. It's quite a bit easier to see when looking at the impulse this way.
You will likely have to zoom in manually to a more sane level though, like down to -60dB or -80dB at the most rather than the -700 or so that it currently auto-zooms to. -
Inappropriate?Thanks, Chris. I did that, and I am taking a guess this is the reflection, windowed, what do you think? I am measuring at 1 meter and I am getting a resolution of 127.83 Hz. Am I doing this right?

Inappropriate?Clarifying what I said above, I think I windowed the impulse, effectively gating out the reflection. I'm not sure if I got the window right. though.

Inappropriate?I think you should try increasing the zoom level a bit more, using the zoom area tool (using the zoom tool, click & drag) to draw a box around the peak to the -150dB point in that graph. See the attached picture.
