Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.For comparative measures, here's a comparison of 10 repetitions of FSAF TD+N (a particularly good run to be honest), and 10 repetitions...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.No difference at 48kHz. 2/10 were no good, and the same amount of variation across the good measurements
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.With latest beta testing I ran first run of 10 measurements successfully, second run produced above problem in 1/10 measurements. So...

Like.
Builds updated today (beta 58) with these changes: Added: Show busy indicator while updating FSAF signal Added: Ctrl+click can be used... -
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I ran the same FSAF test with 10 repetitions. 8/10 measurements look like this: 2/10 measurements look like this:

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Thanks for taking a look. It's very likely that the room temperature was 1-2degC higher in the afternoon. In the afternoon, I was able...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.John, would you mind taking a close look at the attached mdat file? It contains 4 measurements, 2 were taken this morning before I left...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.The struggle I have is considering this knowing that this is a speaker I have designed myself, with a crossover around 2kHz, and the...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.The benefit for myself or anyone else would be to not have to listen to the sweep for a frequency response measurement. For example...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I am still struggling on comprehension of measurement results unfortunately. Below is a test of a pretty good speaker, a 2-way...

Log sweeps extract the linear part of the impulse response, move harmonic components to negative time and distribute other non-linear...
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Thanks John, but timing markers for clock rate correction is not what I'm after. I am after a complete dual channel measurement, where...
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.@John Mulcahy , do you plan to incorporate any of the timing reference functionality of a sine sweep into FSAF? For myself, I have no...
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.John, from some discussions at DIYAudio, should one expect some loopback test with a known harmonic distortion level and sine sweep...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Thanks John. This FSAF stuff is really impressive, thanks for incorporating it to REW! I think it may take some time for it's use and...
