Looking For: Basic Dumb FREE FFT measurement Software??

bear · 23rd April 2009, 01:57 PM

Hi,

I am looking for links to basic, simple, dumb, easy-to-use and set up, usable with internal soundcard, FFT SOFTWARE!!

All I need to do is to look at the SIGNAL sent from a line level device to see if it is FLAT (and not all that closely) across 20-20khz. No brainer, right?

I want to plug in the mini plug into a laptop, put the test signal on the device (externally generated) push a button and capture the signal on the sound card (ok I'll record it as a .wav if I have to) then FFT the result and see what it looks like.

(oh XP, PC)

ANY SUGGESTIONS??

Needs a VST Host.

VST is an acronym for "Virtual Studio Technology". It's a type of plugin for audio software that was developed by Steinberg.

There is a free audio editor called Audacity, which, in addition to being very useful piece of software, is also capable of using VST plugins such as the one mentioned:

Maybe these might be useful as well (I haven't personally used any of them):

Visual Analyser is free and works pretty well. I have trouble getting full duplex to work on a USB AD/DAC but it is fine just in measurement mode. It does 1/3 and less octave measurements too.

Thanks for the link to the Audacity plug in... it will likely work for my friend who is the one who needs to do this trick...

Still interested in what is available in freeware that will do this sort of thing... or more.

Tnx.

"Signal Analyzer" is another VST plugin that can do real-time FFT.

Also possibly useful is "VSTHost", which is solely for loading VST plugins.

in fact the quickest way to find your soundcard performance capbility is to google its model name and RMAA:
