Great thanks so much for this. I knew it was basic. One more question does REW provide an Octave Band Analysis or do we just get the db at exactly each frequency rather than a computed dba summation of the Octave band? I'm presuming i need a sound meter for that right?

The button above the graph? Can yo please be a little more specific? Usually, you press the start button to start a sweep, in this case where do I go to capture the pink noise.

Apologise if the heading isn't correct but I just want to use REW in a room where there is a night club upstairs. I want to measure the full range frequency to see the the transmission loss through the ceiling. If the above sound system plays sweep or generic live white noise, and I have REW on...

Usually on Hangloose if it crackles it is buffer size issue and I have fixed the issue with buffer size with my tri amp system as well in the past so I do suspect it could be culprit. However it is already on the 2048 in the minidsp UAC2 control panel. Shall I try a smaller buffer size and if so...

I have a standard 3 way Audiolense XO tri amp set up and after reinstalling windows I now have some crackling that comes and goes. I used to get this if pitch and tempo was left on in JRiver and with a few tweaks it would go away. Does anyone have any ideas what it could be...?

My apologies just read the spec sheet and apparently the phase doesn't change in BTL mode...

Yes, these amps are tranparent. I just thought the phase maybe played a role when switching to BTL mode.... Thanks.... This is good news.

My limited understanding is that with the Hypex amplifiers in BTL you have to invert one side of the wiring which will put the two amplifier channels out of phase. Does this mean that my woofers will be out of phase?

I might, switch my amp to my mid woofer(midrange) in my tri-amp system from a Hypex NC502MP to a NC122MP in BTL. Does that have detrimental affect on impulse repsonse or group delay or any other factor inlfuencing sound? Regarding gain, I am not too fussed as I often switch the gain from the...

Great, thanks so much. I just had no idea why changes where made in the preferences after I downloaded but then again maybe it had made some changes and just not measured after the change, in any case thanks again. Regarding the ETC I will send screen shots to explain what I mean.

I haven't really changed anything in the preferences. Except maybe keep full IR. Also, the ETC is the way I used to see it in the overlay but not in the main screen but that isn't too important as i can use the overlay to check the ETC. The FR is priority....

I tried with the log spacing both checked and unchecked and I am still getting a FR with 1/48 without it having the option to change it. And the smoothing is definitely no smoothing. This only happened after upgrading REW to the latest version. Could it be something else?

I checked th ebox, I will retest to check if that does the job, not that I doubt you. But, the Filtered IR also looks different than the usual ETC is this the same issue...?

I checked that its checked no smoothing. So am I right to presume this is a bug? I''ll try downloading an old version and measure again.

Oh brilliant, taken me 5 years to figure this out really apreaciate it. Also, I just downloaded the latest version of REW and my new measurements are all 1/48 smoothing and undoing smoothing is not changing it. Any ideas? Next to selection options at the bottom of the screen to choose the right...
