John Mulcahy replied to the thread Impedance calibration problem on REW 5.40 beta 54.As above, it works for me. If you attach screenshots of your Measure dialog and soundcard preferences I can make sure I am testing with...

John Mulcahy replied to the thread I am looking for help getting all test signals out of REW.The HDMI signal is multi-channel linear PCM, it is not encoded. Check your AVR's manual for a surround choice that supports that.

John Mulcahy replied to the thread I am looking for help getting all test signals out of REW.The surround mode should be one that supports multi-channel linear PCM. Some AVRs have limited functionality for front panel HDMI inputs.

John Mulcahy replied to the thread REW Beta Release REW API beta releases.The error buffer might be full with previous errors. I'll add some code to only keep the most recent errors.

John Mulcahy replied to the thread REW Beta Release REW API beta releases.Windows are not affected, but response copy does not include distortion data. If you want an identical copy of a measurement just save...

John Mulcahy replied to the thread REW Beta Release REW API beta releases.Sounds like the way the inverted signal is being generated is causing some issues. Probably worth asking on the thread I linked.

John Mulcahy replied to the thread REW subwoofer delay measurements don't make sense.Delay measurements are unreliable for low bandwidth devices like subwoofers, the alignment tool is best for that.

John Mulcahy replied to the thread REW Beta Release REW API beta releases.I guess you could make a sweep or stepped sine measurement across a small resistor in series with the driver, on the ground side if your...
