Like.
Because there is clipping somewhere along the path for higher levels. Stop over-driving the system or adjust gains to stop the clipping. -
Ddcibel replied to the thread REW Beta Release REW API beta releases.Minor UI stuff, when removing a measurement, any measurement groups that were open will be collapsed. I'd really like it if the groups...

Ddcibel replied to the thread Q to John - How does the sweep work?.I'd answer, but I'm not John, or a John.

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.What I am finding with this testing, is that drivers obviously have very different suspension systems, so free air testing through bass...

Oops, big mistake, post #288, thanks for pointing.

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Are you sure you've got that post # right?
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.If you've not allocated enough RAM for REW at time of install, it will produce an out of memory error if IR length is too long. For...
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Try increasing IR length to 500ms, I can reproduce similarly bad results with IR length too short. I think perhaps 300ms provides the...

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.Same amp loopback measurement as a sine sweep.

Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.I can't speak to your problems @JanRSmit, there's lots of possible causes for what you are encountering. Sine sweep or RTA measurements...

Ddcibel replied to the thread Phase wrapping with loopback.You measured excess phase with your loopback timing reference. It takes time, as in milliseconds, between loopback impulse and actual...
-
Ddcibel replied to the thread Phase wrapping with loopback.If you're talking about using a loopback cable as a timing reference, what you're observing is excess phase due to time of flight for...
-
Ddcibel replied to the thread REW Beta Release REW API beta releases.Currently, SPL scale does not change, but dBFS scale does, and in the wrong direction. I would expect that dBFS scale remains unchanged...
-
Ddcibel replied to the thread FSAF (Fast subband adaptive filtering) measurement.If you are talking about the TRS vs XLR for 48V phantom power, I've used 3 different audio interfaces, and found this to be true of all...

Ddcibel reacted to FSAF's post in the thread FSAF (Fast subband adaptive filtering) measurement with Like.
I have been playing with current measurements for quite a while but have not found a way to make much sense of them. First, you need a...
