Good FFT Software with WHITE window?

[ssashton]

Hi Everyone,

Just a quick question - I like the FFT spectrum analyser in Adobe Audition, but I want to put the results in a document so the dark theme looks bad. Does anyone know a good option with a white / light theme?

I already recorded the .wav files - 80Hz sine stimulus to analyse distortion and noise products, I can not go back and do it again. Or perhaps I can export the Audition data as FRD etc? Help appreciated!

I tried REW but when I import the .wav file the results look a mess. Perhaps someone knows the settings better than me to get a good result? Looks like a windowing issue.

I Also tried Audacity but I can't see how to expand the graph range below -90dB.

Thanks, that's not terrible. I did try 'colour replace' in Photoshop but it didn't look good.

Try smoothing in REW.
Step 1 - Click on "Actions"
Step 2 - Selection amount of smoothing from "Smoothing" drop down
Step 3 - Click "Apply smoothing"

Result of 1/12 octave smoothing

Thank you for your help. Unfortunately this does not show the detail I need. This is a speaker port noise measurement where I want to see the spikes, but also the broadband turbulence noise in the floor of the measurment.
