However, if I import RTA data with banding set to “None” and then run ‘Octave smoothing’ the tilt does not change.
That is correct. FIR Designer works fundamentally with transfer functions, not power spectrums. So when a RTA spectrum is imported into FIR Designer, it’s shape is essentially treated as a TF spectrum (but without any phase), which is why the smoothing function does not act like “banding”.
We provide RTA importing into FIR Designer for convenience, since often it’s helpful to design EQ based on a RTA measurement. So when importing a RTA measurement, we recommend applying the “banding” in SMAART before importing.
Please add “stop generator after Capture’ beside of ‘Signal generator”
‘Signal Generator’ buttons are too far from ‘Reset Time averaging’. Please move to above ‘Signal generator”
We will consider this but no promises. 🙂
