    The links in the first post are still pointing at 91 for me.

    Testing Individual Drivers in a "9.1.4" Samsung HW-Q950T Soundbar System

    Not sure what problem you hit; I've used REW with 7.1 output to a Q950A and Q990D. You can find REW compatible frequency sweeps in that post and pink noise files in that post.

    Yeah, I guess that will work, if the outputs are clean enough.

    I have DUT output going to a digital capture card, with a separate app that's controlling the capture and producing a multichannel WAV file. There's no Windows input device to point REW at. Otherwise I'd have to try writing some code to try to identify the right sections of the timing ref...

    FSAF (Fast subband adaptive filtering) measurement

    It would be useful to me, but it's admittedly not a normal use case.

    Normal playback measurement doesn't work for my odd use case. To analyze a digitally captured LFE channel, I need the timing ref on a separate digitally captured channel, and import of the resulting pair.

    FSAF (Fast subband adaptive filtering) measurement

    I see the Generator supports creating FSAF files, but I don't see a way to perform FSAF analysis on offline recordings. Am I missing something, or is that on the wish list?

    When importing sweep recordings, would it be possible to support a response file that has the timing ref and sweep on different channels?

    Does the Soundcard preference to treat 32-bit data as 24-bit also apply to importing WAV files?

    Ah, I get it, thanks!

    If I use a generated sweep like 256kMeasSweep_20_to_20000_-12_dBFS_48k_Float_ref.wav as both stimulus and response for import sweep recording, and then look at the Clarity graph, C20/C50/C80 go off the top of the graph, and Fit to data doesn't help. But Fit to data does work in the Clarity...

    Thanks. If I use a generated 128kMeasSweep_20_to_20000_-12_dBFS_48k_Float_ref.wav as both stimulus and response for the import, I also get a high distortion warning, but looking at the resulting phase data, perhaps that's a different problem?

    If I mistakenly import an all-zero channel as a sweep recording, a java.lang.ArrayIndexOutOfBoundsException:0 error pops up, prior to the warning that the data is zero and was ignored.

    REW Beta Release REW API beta releases

    When I import the R channel of the attached stereo wav file as a sweep recording, against a 1MMeasSweep_20_to_20000_-12_dBFS_48k_Float_ref.wav stimulus, I get a warning that the distortion is 73.2%. But when I look at the Distortion graph with % selected, the max seems to be less than 4%. I'm...
