Measuring distortion

Buzzy · 2nd November 2008, 10:10 AM

Is there any software that i can use to measure harmonic distortion of a driver or speaker ?

www.speakerworkshop.com - free. up to 4th order harmonic only

I think Arta does this also.

SoundEasy as well as others.

The last time I tried using SW for distortion measurement (a few months ago), it didn't work, so I bought a copy of soundeasy...

In speakerworkshop i can't find the distortion measurement. the help file does not show how. Any one know how to do the distortion test in speakerworkshop ?

ARTA does an accurate measurement of individual harmonics and THD using the STEPS part of the program.

Make a new 'signal'. Select it (double click), then go up to the menu 'Measure' and select 'Harmonic Distortion'.
