Ddcibel replied to the thread Oops, wrong UMIK cal file.You can select "change cal" on the measurement.

Like.
Not for the FSAF distortion plot, that shows the input spectrum as the fundamental. You can see the TF in the SPL & Phase plot. An odd... -
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Yes, the results are as expected if I compare for example a 100Hz high pass to 200Hz high pass, in that the tweeter distortion stays at...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.If I could return to this original problem on pink noise with no filter vs pink noise with a 20Hz high pass. Now that I have much better...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.How should I interpret the SPL on the distortion chart as far as the absolute level? If I recall, the level was 90dB via the "check...

Ddcibel reacted to John Mulcahy's post in the thread FSAF (Fast subband adaptive filtering) measurement with Like.
They show different things. The SPL tab is showing the transfer function magnitude, offset to be representative of the test level. The...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I'll test a bit more on that spike. It could be related to some other problem, perhaps a leaking baffle seal or something buzzing. It...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I believe this is a problem inherent to the Satori MW16P, caused by cone-surround interaction to my knowledge. Speaker 2 above was...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Thanks for taking the time to analyze my measurements. I must apologize, a few sentences into this explanation gets over my head a bit...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I've sent Mike the same MDAT and residual files that I sent to you previously. I'll have to re-do the measurement with the other...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I've tried pink noise, and 15s music clip. I've sent you a PM with the same MDAT and residual files I sent John previously. It doesn't...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I'm not trying to measure LF nor do I care about it at this moment. I'm having issues with FSAF measurement repeatability, and currently...
-
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...
