Question Easiest software to measure the Frequency Response

Hello !


I want the easiest possible software (freeware is better) to measure the response frequency of my loudspeakers.

There's no need to be very accurate or have a real plain frequency response (calibrated microphone etc.), it's just to compare two loudspeakers, that one is the reference.

What would you suggest ?



Thanks !


Best Regards,


Fernando

Probably the best for your purpose is True RTA.

I'm trying the Speaker Workshop, but I'm having problems.

The microphone response must be set through a dataset archive. But I don't know how to create it !

I'd like to try the Speaker Workshop, because it's free and seems to be a great software, and also can be very accurate.

The RTA is an interesting software, but the free version is not much useful

Try audiotester. Free demo, cheap license. I found it one of the easiest to learn and use, _much_ easier than Speakerworkshop which must be the worst wrt user-friendliness.

Default ARTA

Try the ARTA family. The demo is without any restrictions regarding measurement, just the file handling is limited.

http://www.fesb.hr/~mateljan/arta/download.htm

Furthermore you will find a lot of supporting papers in the download area.

I'm also having problems with setting up "Speaker Workshop", but I assume that these are due to my old amplified sound card.

Also, the proposed jigs, give more confusion than help. The software request me to use one to measure passive components. If I do not do in this way, always indicate to me that "probably I have an open circuit". When I use the jig, in the x1/10 option, I do not know what I am measuring. Anyway I am still trying to understand it.

SW forum also looks a death forum.

Hi all,
Fernando in my HP you can download the GENERIC calibration files of the most used mics.
Anyway, I don't think SW doesn't work without a calibration file, simply doesn't compensate for it.

Hugo, SW forum is not dead at all! Of course after so many years of life it's quite for sure that the most was already asked and probably answered. The SW forum is full of info, so doing a search you get your answer and there's no need to open a new thread. Besides, SW is the same since 2002, so no new problems arises in these years.

A new life to SW should come in the future, since Mark Zackmann published the code.

This ARTA is VERY GOOD, although I don't see an option to correct the mic response. But is so easy, just run two seconds of pink noise and your response graph is on the screen !

I compared my speakers with ARTA, and I really detected the horrible peak in 3khz, then I ran some sinewave with TrueRTA (free), and the audible diference between 2000Hz and 3000hz is frightning. Now I'll work in a eletronic notch filter and equalization to compensate the &$$#&* that the sound is now


Claudio, thank you very much, now I'll try SW !


Best Regards,


Fernando

The software available look interesting.

Now, if we could just find an available, affordable, and reasonably good microphone

I have searched the forum, but the answers seem to indicate several 100 $$$ s worth of Behringer, almost as much as a good ready-made loudspeaker (god forbid!).

Panasonic makes some good (20-20khz?) electret microphone capsules (cost is about 2$), the same that are used in the Behringer. Just add phantom power, a thin stick to hold the thing and some wire and you're done. I think digikey carries them. typenumbers differ for European and American market.
