I've figured that out. The workaround at the moment is to not let q = 1, but always slightly smaller (0.995 is fine).

I’m sure the comfortable folks in West Linn are used to much worse from across the river. You should see OC now... but I digress off topic

But that is soooooooo much technicality, and not the least to do with anything that matters real world.

But even technically, another great thing about dual-channel using pink or music or whatever, is that it allows real-time temporal averaging, increasing accuracy beyond that of a single sine sweep.

But that said, you could average multiple sine sweeps as REW explains, and maybe achieve even greater technical excellence ....

And make everybody, including ourselves, even more ultra annoyed !!! LoL

Angelo Farina, the author of the ecponential sweep method, has shown that the best, most accurate, result is when you use one really long sweep instead of averaging.

( which is of course even more annoying, I know )

Interesting! I'll need to try that out.

(Original post said "I'll need to increase my length" and I realized that was NSFW)

Ha! That's exactly the town I was talking about. Right across the river.

I'm having a bit of trouble getting the reports to work, seems like it might be due to my file structure but I can't quite work out what I'm doing wrong, any ideas?

[miero]

fluid, try to remove whitespace from the directory name "ATH FILES"

[tmuikku]

Hi, you've got space in the directory name which ruins the command. It just renamed my problematic folder, couldn't figure out other way around

[fluid]

You were both right, now it is working Needed to make a new directory structure for 4.7 otherwise my old files would complain about being in the wrong place.

You are the first one!
