Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Just to highlight the variability in low end noise. Below is 10 sine sweep measurements, and 10 FSAF measurements. The FSAF measurements...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I have to think that this problem is somehow inherent to my use of Motu M4. I've changed all other variables and receive the same...

Ddcibel replied to the thread REW for the first time.1 and 2 are the same, 3 I have provided for you, it is the same but with a voltage divider at the soundcard input to step down the...
-
Ddcibel replied to the thread REW for the first time.Any resistor is fine really. REW's calibration process will compensate for the resistor and test lead inductance, so I'm not sure why...

Like.
MacOS has the same behaviour, I have added a fix in the next build. -
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Thanks for taking a look, John.
-
Ddcibel replied to the thread REW Beta Release REW API beta releases.Yes, on Linux. I have a similar behaviour with the "add a number to the name" context menu.
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Today I caught REW adjusting timing by -0.11ppm, I don't think it's done that before. This is possibly the worst selection of 10 repeats...

Ddcibel replied to the thread REW Beta Release REW API beta releases.Minor bug report. In the measurement setup, when entering the number of measurement repeats, if you don't hit the Enter key in the box...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.So far I have tested either with 5s pink noise, or 15s music clip, and two different speakers. Unfortunately I don't have another audio...

Clearly your loopback with audio interface only and audio interface + amplifier can give consistent results, which means that your setup...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Good idea. Here's loopback with a real music clip, 15s playback, 10 repetitions. ...and the same music clip through the speaker and...

It's odd. Perhaps some tests with a music track and comparing the residuals would give some clues.

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.FWIW I also tried on windows with ASIO driver and got a similar result. I ran a loopback from the amp output (simple voltage divider to...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I thought I would try as well to use pink noise from a file, but no change there either.
