Audio Frequency Counter

Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period. FOR INDICATION ONLY. Results depend on your device and its hardware. If you just want to know the frequency of a sound with harmonics (e.g. mucial instrument), a FFT based app such as keuwlsofts spectrum analyser or guitar tuner (both free) will be better. This app can provide more accurate frequency measurement for single frequency input signals. Features include:
Display of triggered event count and frequency or time period.Graph of input signal, 2.5 ms/div up to 640 ms/div.Gate time of 0.1s, 1s, 10s or 100s.Gain from x1 to x1000.Trigger on rise or fall.AC or DC coupling.Set a noise level so new event is not triggered until the signal has first passed this level.

More details can be found on the website.

It definitely works. I got a gadget and had to test it somehow and when I turn it on the app detects the frequency immediately.

top notch app, while it's not as accurate as regular frequency counter, it still does it job well. i tested this on a 1000 hz and 500 hz audio and the frequency that was shown in the app was correct.

The reading i get is accurate , as i wanted to test a gadget i download this app. The gadget is anti repellent insects , and since it works on low frequency i couldn't know if the device is working or not so i tried few apps and discovered this app and the results was accurate.

I tested this app with pure tones and it works perfectly. Dont go buy the titles on you tube that suggest 528 hz most of them are not even close to accurate. Look for pure tones with this app.

Super accurate, I measured a 0.1 Hz difference at 360Hz. You have to push all the buttons a few times to figute out whats going on but it has good features. Also, free

This app does exactly what it tells. I have compared the readings simultaneously with an oscilloscope and the frequency difference is only about 100-500 Hz.

Another dumb dog app it recieves from the microphone and the g.u.i outlays the graph in the form of a decibel wave chart since most phones have no hardware on board that can measure electro magnetic emittance and hense why this app is a helarious attempt of a waste of time by our security employees to send poor people down the app rabbit hole

๐ŸŒŸ Great application just what I was looking for. it would be nice if I could choose a sound pitch or tone to count. otherwise, this is one of the better applications I've used for this purpose. Thank you developer! ๐Ÿ™‚

i am experiencing extreme ULF sound in my home. It's a low low oscillating droning sound. My eardrums are vibrating otherwise i can't hear it. i chkd my appliances,a/c and listened to my walls to see if it's my neighbor. nothing. very weird. I dl'd this app to see if i can measure the Hz level. Is this a helpful app for this purpose or should i D/L a different one? I'll check back later

Awesome!! But can be improved, you can add some information like the avg reading and an option to down the recorded results. Again awesome app!!!

great! it counts rotation frequency of skate wheel, seems well. Please do a possibility to write a log file. I need to analize a speed of decreasing frequency.

What does this counts are in audio frequency counter?

Rus. W. Jan 26, 2019     

This app is very accurate and allowed me to identify an issue with one of my DAW plugins not referencing A 440.

NOH. Oct 6, 2019     

I got this app becuse there was a sound that was being bothering and i tested and this app found the place the sound was coming thus app was very helpful

Kha. A. Feb 9, 2021     

Nice thanks but must have color picker and switch for mic for audio innt source colors choices for oscilloscope ^_^

Plo. t. t. Jun 23, 2021     

It's completely accurate. I reccomend this app over spectroid due to the accurate reading.

Mat. D. C. Jul 27, 2021     

Thank you very much I'm really grateful, cause this app works perfectly thanks to that I can make my project.๐Ÿ˜

Iul. J. Apr 26, 2019     

Very acurate. Found it with only 0.5Hz diference than the reality between 70Hz and 19000Hz

Bob. P. Apr 15, 2021     

Excellent piece of software. Very accurate. +/- 1Hz

Han. E. Mar 5, 2019     

very accurate i tested with different tones and it was right

Den. F. E. Aug 14, 2019     

Hello I thank the developers for a great looking app if it really does what it says then maybe theres a chance Id give 5 stars its at 4 now.

No where near! Even with a tuning fork it is miles out.

Pan. S. Mar 9, 2022     

Gives completely right information

Lnr. B. Jan 1, 2022     

I use this tool quite a lot when I want to know the frequency of that squeal.

Fak. N. May 21, 2020     

Wil this app be updated to support high refresh rate displays?

ser. r. Sep 25, 2018     

One of the most useful app for speed calibration

Ric. K. May 12, 2021     

Its a sound frequency apps

POO. K. Oct 8, 2020     

It gives exact frequency.Better than higher rated apps

A. G. u. Mar 3, 2019     

good app with various features
