Audio Analyzer up to 45khz

Hello,

Anyone know of a free audio spectrum analyzer for android devices or windows PC's that can 'hear' up to 45 KHz?  All of the ones I googled (so far) top out at 22 KHz.  It's for my dog who apparently hears things that I don't.  I'd like to track down what's bothering her.  Not sure if standard mics on a laptop are filtered for normal human range or not.  I have the Adobe suite of products so I could use Audition if that helps?  Maybe capture a sample and try running it thru Audition but I don't know if that goes up to higher frequencies either.  Maybe a nature sound analysis program?

I have programming knowledge but it seems like quite a project to create a custom sound analyzer...

Thanks

Spectrum Analyzers are anything but free.

Here is a decent one that is software https://www.trueaudio.com/rta_abt1.htm and permits a trial for you if you think it is worth it.

It is not expensive to purchase

Hmm, it looks like it might work if I had a sound card that could sample at 96khz.  None of my laptops do, I'll have to look into my PC sound card then find an external mic.  

Will it always depend on the sound card having 96 kHz sampling rate even if I only want to get to 40-45 k hz?


I was nosing around this website but couldn't find anything to download that would suit my needs

Looks like I am using the onboard / mother board sound capabilities. No sound card.  Trying to figure out what the capabilities are to change the sampling rate and can't find them so far....

Windows 7 pro, intel motherboard.  Not sure on make ATM.

Any ideas?
Bummer,  found "supported formats" under AMD HDMI Output Properties at least and it only goes to 48khz.  Not sure if more options would open up if I plug in an external mic.  guess its DOA at this point.

Unless someone knows if it can be done with only a 48 KHz sample rate?
I am not sure why the sample rate needs to be exactly 48 KHz. Sampling can be done at a different frequency and preferably higher sample rate so you can see the audio distribution
In the FAQ section for TrueRTA it says it needs at least 96 KHz of sampling to provide analysis up to 48 kHz.

If there are other apps that can do it with less sampling rate then I haven't found them yet.
I misinterpreted your sentence "only a 48 KHz sampling rate"  Yes, of course you need a higher frequency (96 KHz would be the minimum). This will be true in hardware Spectrum Analyzers as well as software.

My Digital Oscilloscopes sample at ten times or more the waveform I wish to display.
Playing with adobe audition for a few minutes and *kinda* looks like it might allow sample rates up to 192,000 hz.  Just need to try to find a mic - or install it on a laptop.  Think I might have one in the basement.  I can try to connect it up to Audition to capture audio.  For now I need to take said dog for a walk.  

John,  thank you for your thoughts so far.  I'd like to leave this question open in case anyone else has solved this problem and has a free (ish) and easy solution.  This is just a one time capture around the house to make sure the dern dog is happy.

Fast response and right on.  I need a better mic.  The only ones I have handy are boom mics for a head set.  Adobe Audition has everything I need including tone generation, spectral analysis, and 192k sampling.  Easy as pie.
You are very welcome. Sometimes my electronics experimenting in the basement comes in handy
Incidentally,  I discovered a tone of 19,000hz makes everyone in the house stop what they are doing and cover their ears in pain...except me...completely oblivious to it.  BAW Ha ahahahaha!!  Maybe I'll set up speakers on a Bluetooth remote....
Thanks for the update. Maybe you (like me) have a hearing deficiency at higher frequencies.
