Use Audacity as speaker analyzer

As stated in post 18 and on title of results, mike was 6' from speaker front in all cases. 6' is > 2'. Thanks for reading.
Those 1 meter mike to speaker measurements are standard, but don't remotely simulate how I listen to a speaker in my music room. 10' is more usual.

Yeah, I can read.
What I'm saying is that because you're using a mic that does have proximity effect, you'll need to vary your measuring technique to get credible results - being more than 60cm away (IF your mic is a close enough clone of the KSM27) means it will be under-reporting the level of LF. Closer than 60cm and it will over-report the LF.
Measuring at any other distance than that means you don't know what you're measuring.

Of course, if your clone isn't particularly close, then it doesn't matter, as you still won't know what you're measuring.

Avoiding these complications is one of the reasons why proper measurement mics are always omnidirectional, not cardioid, as that eliminates the proximity effect, and why they come with calibration files to correct for any frequency response irregularities.

To run the REW installer, did you make the .sh file executable?

In your terminal emulator, type:

Code: 
chmod +x /pathtofile/file.sh
./pathtofile/file.sh

Just out of curiosity, I tried opening my REW installer with nano text editor and it worked.

Thanks IG81. When I try to read about bash it always wanders off into scripts and branches and program flow and things I'm extremely not interested in. I remembered the chmod command but not the +x part. REW installed and came up. It does recognizer the mainboard intel A/D chipset. Will wait a rainy day to hook up amp & cables to test speakers.
