John Mulcahy replied to the thread Confusion about FFT length and Max overlap.I can't follow the logic of combining a long FFT with heavy smoothing, but that is very likely to result in skipped sample blocks. The... -
John Mulcahy replied to the thread Confusion about FFT length and Max overlap.More overlap means more frequent updates since fewer new samples are required to calculate the next FFT result.
-
John Mulcahy replied to the thread REW multiple instances on Linux.There's nothing in REW that enforces single instance. It's possible the installer shell script has some content that requests that, but...
-
John Mulcahy replied to the thread Measuring Bluetooth delay.Yes. REW will measure and show the system delay relative to the loopback in the measurement notes, after removing any timing offset...
-
John Mulcahy replied to the thread REW multiple instances on Linux.The REW installer only specifies single/multiple instances on Windows, otherwise it relies on the OS behaviour.
-
John Mulcahy replied to the thread Newbie question - REW and Umik-1 problem.Please use the "Generate diagnostic file" option in the help menu and attach the file, making sure the mic and devices are connected first.
-
John Mulcahy replied to the thread Create and export Room Response.The room response is the impulse response, you can export it as a WAV file.
-
John Mulcahy replied to the thread Measuring Bluetooth delay.You would need to provide a loopback timing reference channel to allow the delay to be measured.
-
John Mulcahy replied to the thread Newbie question - REW and Umik-1 problem.REW may not be able to identify the mic as UMM-6 depending on how FlexASIO has handled the naming. Try the Java WASAPI Exclusive drivers...

John Mulcahy replied to the thread Is it possible to display total RMS of a measurement?.You will see a 3 dB difference in the dBFS values depending on the setting of the View preference "Full scale sine rms is 0 dBFS". REW...

John Mulcahy replied to the thread FSAF (Fast subband adaptive filtering) measurement.I should have checked my code before replying, the first two seconds of the mic wav file is the silence capture. The exc, res and lti...

John Mulcahy replied to the thread REW won't install on MacOS Ventura 13.7.1 M1 Max Macbook Pro.Someone had a problem running the installer a few years back that related to the display colour profile, perhaps the HDR setting reset...
-
John Mulcahy replied to the thread FSAF (Fast subband adaptive filtering) measurement.The residual is aligned so that the stimulus, capture and residual can be compared at the same timestamps, putting extra content ahead...

John Mulcahy replied to the thread REW won't install on MacOS Ventura 13.7.1 M1 Max Macbook Pro.Which version are you trying to install? Getting debug is a bit more complicated on macOS. In Applications/Utilities open the Terminal...

John Mulcahy replied to the thread Measuring capacitors and inductivities not related to speakers.Sure, same as any other impedance measurement. REW can fit a component model to the measurements after you have made them.
