Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I have nothing to gain or reason to present "fraudulent" data. I've already got what I wanted out of the little experiment so draw...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Filter settings are in the notes, when no filters are used, no note.

Like.
@Berndh Why the noise is different? This is one of the "why" questions I have no answers for. It's all my fault. The REW LP filtering... -
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Glad I could help with the evaluation. It's really interesting to run these comparisons, and I am still baffled by the magic that has...

Ddcibel reacted to FSAF's post in the thread FSAF (Fast subband adaptive filtering) measurement with Like.
I am glad that FSAF, however imperfect, helps. My experience agrees with @dcibel. Driving a woofer in a 2-way configuration below 2*Fs...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I did! Exclamation point! Both of my files sound the same, only audible difference is amplitude. Adjust for same volume and they...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Sorry, perhaps I did not complete a perfect replication of your test. When measuring with the pre-filtered file, I turned filters in REW...
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Difference in level was 3dB between pre-filtered and REW filtered measurement. When I adjusted the level by 3dB, overall distortion...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.If I understand correctly, you are comparing two "identical" files, one is a pre-filtered file, and the other is filtered by REW. I...

Ddcibel reacted to John Mulcahy's post in the thread REW Beta Release REW API beta releases with Like.
Builds updated today (beta 59) with these changes: Added: Multi-input capture has options to align the individual measurements to the...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Overlay of the 3 measurements in the previous post. Frequency response of filters applied.

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Much testing over the past day. Comparing my large condenser to small condenser, the large condenser provides a bit better noise floor...

Ddcibel replied to the thread REW Beta Release REW API beta releases.Hi John, As a small feature request, could you make the SPL level calibration window open off to the side of the SPL meter display...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Precisely, so I would make a few for my commonly used measurement distances. For example, I usually stick to 315mm for distortion, as it...
