This is mostly a natural and credible recording. For an inexpensive recorder, the clarity and noise lever are surprisingly good. The 3-second silence at :39 seems out of place - were two separate recordings pasted together there? There's also a human voice saying "test" (?) at :52, and what sounds like wind noise (or could be handling noise) near the end. However, these problems can be fixed with just some minor editing. Thanks for posting this recording.
Its just such a high frequency it irritates the treble sensors in your ears. The problem I'm having is it seems to disagree with some speakers/headphones. It works fine on my laptop speakers, but my studio headphones distort when it gets to a certIn point. May be a manufacture error in the headphones, but they dont agree with that frequency. I've found it with another similar sound on this site as well.
