-
John Mulcahy replied to the thread Optimal REW settings for measuring amplifiers.Looks like an issue with clock rate differences between the input and output devices. If you add a loopback connection as a timing... -
John Mulcahy replied to the thread IMD Measurements: "Generator" vs "Input" Level Discrepancy.The code is the same on all platforms, so differences are likely due to local settings such as whether you have chosen to display phase...
-
John Mulcahy replied to the thread UX suggestions for measurements list.Use the V5.40 beta version, it has a lot of changes including an option to put measurements in groups and sort the list alphabetically.
-
John Mulcahy replied to the thread Optimal REW settings for measuring amplifiers.The distortion limits for most published specifications are 20 Hz to 20 kHz. Sample rate will have an effect if your limits exceed half...

John Mulcahy replied to the thread IMD Measurements: "Generator" vs "Input" Level Discrepancy.Which REW version? The V5.40 beta builds got this fix in May: Fixed: When stepped IMD measurements are plotted against the input level...

John Mulcahy replied to the thread REW Beta Release REW API beta releases.Was that after dragging a measurement?
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Builds updated today (beta 101) with these changes: Changed: When the FSAF excitation for a file measurement is saved there is also an...
-
John Mulcahy replied to the thread Distortion Measurement - Generator Calibration Value - Export.You can see it on the Info panel for the measurement.
-
John Mulcahy replied to the thread Cross core align.The responses are being aligned, not just one part of the response. The difference in timing of the peaks you seem concerned about is...
-
John Mulcahy replied to the thread REW Beta Release Scan for speakers.Debug information about the attempt to communicate with the 8c is logged in the rew_output.txt file in the REW log files folder, whose...
-
John Mulcahy replied to the thread REW Beta Release Calibration Loopback Setup Help (UMC204HD).Calibration is done with the measurement output and the measurement input. If a loopback connection is to be used to provide a timing...
-
John Mulcahy replied to the thread My go with REW, getting popping noises on audio out.That's a misunderstanding. The base Java drivers only deliver 16-bit data, the EXCL device entries deliver the full capability of the...
-
John Mulcahy replied to the thread REW Beta Release Calibration Loopback Setup Help (UMC204HD).Your soundcard preferences show the left channel as input but you said your cable was going to the right...
-
John Mulcahy replied to the thread Feature request: In overlays be able to display more than just one harmonic at a time.That would be difficult because it would be hard to distinguish which trace came from which measurement. For Overlay graphs each trace...
-
John Mulcahy replied to the thread Optimal REW settings for measuring amplifiers.Generally best measuring at the lowest rate that covers the bandwidth you are interested in. Can't think why you would. For RTA...
