Audio Spectrum Monitor Customer Insights

1. also didnt seem like it would enumerate and select connected usb otg microphoneswhen i try to import some audio... its crashed immediately... a little sad.. huhu everything is great but only that problems.. i hope you can fix it better thankyou!Get rid of the bloody adds give people the option to buy the program for a couple of £ can't you see the adds destroy your application.IF WE COULD HAVE PLAYED SONG IN THIS APP WITHOUT FOCUSING ON EXTERNAL SOUNDS TO EXTRACT THE NOTES OF THE SONGS THEN IT WOULD HAVE BEEN BETTER.

2. Would give it 5 stars if there was a paid version without the adds!I made some EVPs at a abandoned grocery store and I actually captured some good results with it plus with the graphic spectrum in the app I could actually see some sounds that I couldn't register with the naked ear so to me this thing is legit.

3. You could find one that LOOKS better, but you won't find one that PERFORMS better.I love the look and feel of the interface! It feels like the right balance of complexity and usability.

4. Very responsive, not flashy, a lot of options in the settings, a hold button that lets you freeze the display, and a record function.

5. I'm not a musician, I'd like to see the option to switch from tone NOTES to a Hz/MHz reading.

6. Also, why can you not have the whole spectrum/scale on the screen (?) IDK what I'm listening for in real time, n have to drag back n forth to see what I might be missing at the other end.

7. What's the purpose of "P&Z" using 🎵 notes rather than MHz that reduce endlessly (?)Solid app.

8. The only app (next to SPECTROID)that successfully picked up any trace of the LFI's that I am tormented by day and night.

9. You all be the judge people.crashes so i wasnt able to use it.

10. WHY ONLY .WAV FORMAT SUPPORTEDUseless.

11. Very Recommended.
