Hi, could you suggest a spectrum analyzer software for Mac or PC, perhaps for free? I would like to start measuring how my speakers respond in the listening room. If you can suggest me how to do it. Thank you
Adding just a tad to the previous post, more information on REW can be found here:

I suppose you want "simple"?

Get one of these and a smartphone app for 10€.
Nothing cheaper or simpler, even a calibrated microphone!
50€ and your are ready.

Thanks for the suggestions, I'll try using REW. I have two microphones that come from my musical past, a Sennheiser BF504 and an Electro Voice PL80 that I would use with a microphone pre connected to the PC, are they suitable for the purpose? If they are suitable, which of the two do you recommend I use? I attach a pdf of the microphone specifications (the BF504 has the same characteristics as the MD504 that I attach). Thank you
Sorry, these are not useable for any meaningfull measurements.
You need something like this:

For serious measurements you need something that comes with a calibration file, like here:
https://www.thomann.de/de/sonarworks_soundid_ref_measurement_micro.htm
You also need a linear preamp and an interface to get the sound to your PC.
Then wire up the whole thing. Now you still don't know how loud this really is, you need a calibrator to get absolute level:

Now you know how loud the measured data is. To correct for the microphone you have to enter the correction file.
Done. You can measure...
Understand why plugging a small device into your smart or i-phone is simpler?
The quality of these little Dayton gadget is much better than one would expect.
If you handle it well you get near to +- 1dB. Surprisingly this better than you can expect from some professionel measuring gear. Your phone has much more CPU power than any expensive stand allone measuring system. Which pays of.

CPU power makes taking in and processing the data in near real time possible. Maybe have a look at some apps and what they do. The accuracy is dependent on calibration and the number of data taken and averaged over time, but you know that. I know that some are not comfortable if some stupid 15$ part works just as well as their expensive Class XY measuring system they have spend thousends for. Sorry, this is how progress works.
These cheap stuff is not for academic work, but makes it possible for the average hobbyist to take useable measurements, close to reality. I prefer my "real" microphones too, but use a Dayton as well. It works better than it should, compared to price.
