Like.
Triangular high pass dither is added to file data as required to ensure the excitation has sufficient HF energy for the FSAF processing. -
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.@John Mulcahy , I've noticed when playing back an audio file, that the silent passages aren't silent. There is an abnormal level of...

Ddcibel replied to the thread REW Beta Release REW API beta releases.John, Could you fix the text of FSAF notes to just say "None" when no filter is selected.

Builds updated today (beta 62) with these changes: Added: Double-clicking a measurement on the All SPL or overlay graph selectors makes...

Ddcibel replied to the thread REW Beta Release REW API beta releases.Just right click on the measurement on the left side and adjust level from there, or from the All SPL tab you can right click and align...

@Tikkidy : yes, please! I'd like to examine the recordings spk/mic, both ESS and FSAF for the same setup. Could you use noise and music...

Ddcibel replied to the thread REW Beta Release REW API beta releases.That's unfortunate. I was hoping that something like pink noise with a pre-defined filter that matches the spectrum in my screenshot...

Note that I have only added Michael's improved filters. He has made many other changes in the subband processing, but porting those...

Ddcibel replied to the thread REW Beta Release REW API beta releases.Thank you! One more request would be to add M-noise to REW's signal generator and FSAF signal drop-down. Of course I can run the noise...

Yes, I have added that for the next build.

USER ERROR yet again. :gah: Thanks to @dcibel for the tips, as well @JohnPM for previously mentioning about displaying measurements in...

Ddcibel replied to the thread REW Beta Release REW API beta releases.Thanks John, I will try and find some time this weekend to test the improved FSAF routine. As a simple feature request, since FSAF...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.You've missed the word "not".
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I think the question is simply why the noise floor SPL is rather high at 50dBSPL, a quiet room would expect background noise in the...

The sweep noise floor plot takes into account the process gain applicable to the sweep length so that the noise floor plot can...
