Easiest and fastest way to measure a crossover's transfer function?

454Casull · 8th August 2009, 03:05 AM

I'm building a bunch of active filters and I'd like to simply plug them into my sound card somehow to measure the frequency response. What's the best way to do this?

Do you have software like Adobe Audition or MATLAB? Those tools have signal creation and analysis functions.

Or google "Visual Analyser" by sillumsoft (sp?) for a free soundcard analyzer.

Hello,
I have used ARTA on a PC to measure the frequency response of some active filters. In demo-mode you have all functions you will need but you can not save files and projects. I have used sceenshots to compare different graphs.
