Speaker response graph program?
« on: 14 Apr 2008, 12:57 am »
Is there a web-based program out there where one can fill in the spl values taken at 1/3 octave and get a graphic representation of a speaker response?
Something similar to those where you can plug in speaker parameters and make your own crossovers.

Thanks for that program. I d/l it...lotsa features, but couldn't find a way to manually enter the measurements I already took. But I guess I can use it to take "official" measurements...now I would need to get a mic with a long enough cord...mhnnn...

You want to go to File -> Import Measurement to load a pre-measured file. Synrta and speaker workshop are some other freeware alternatives --speaker workshop has a pretty steep learning curve.

Yeah I did that, but...my measurements where taken with a Radio SHack meter/Stereophile test cd, so its all hand written on a piece of paper, its not a computer file which is where that "import measurement" lead to...
Guess I will just have to get the graph sheet paper out and transcribe it manually(long hand).
I will check out those other mentioned programs...
Thanks.

You could enter it in to a file and then import that to REW.  But if all you want to do is make a graph, there are hundreds of programs that will do it for you.  Here's the first hit from google:

I see, you just want a graphing program. You can enter them in tab or space delimited text file and import into REW (as opaqueice suggested) or download one of many graphing/spreadsheet programs --openoffice, gnumeric, gnuplot, octave, excel, ...

The Stereophile test CD is not suitable for measuring the bass response in a room. Room EQ Wizard is much better. So just measure again using REW. That's the best way to know what's really going on in your room.
