How to create a wav file that is outside of human hearing range

[sudo-ninja]

This may be a noob question, but is there a way to create a wav file (tone) that is around 99khz? Is this possible?

Set audacity to 384khz, generate 99khz tone, done.

And be careful not to blow your tweeters trying to hear ultrasonics.

And when you DO hear something it may very well be a distortion product.

Good point. I've heard people falsely claim that they can hear well into the ultrasonics, and even I once thought I can hear 21khz tones through my headphones. The thing is, if you need to crank up the volume massively to hear it, you are probably hearing something else, could be a distortion product. Your useful hearing cuts off at the point where while maintaining the same volume, you're going up in frequency but can no longer hear the difference between on or off.

Thanks so much. Unfortunately, Audacity wont let me create a file with 99000Hz. The "OK" button is greyed out at that frequency. The OK button disappears with any Frequency over 22050Hz. Am I doing something wrong?

nm. I figured it out. I needed to change the Project Rate.

I am curious what you need the 99kHz tone for ...

22 kHz is plenty high enough to be inaudible, and you can do that with a standard 44.1k sampling rate.

To mess with the local bats?

Who knows, though I'm curious as well. Could be something like checking a frequency counter. Not enough digits for 100 khz so 99 khz is just enough. Maybe some experiment to use a high tone as a timing reference without having to buy specialized gear. I once used a headphone adapter from my phone to feed a 25 khz squarewave reference tone to a digital rpm measuring device for calibration. It was in the field and I needed software to play at 88 khz so I could generate such a tone. And fortunately the headphone jack on my phone actually went that high in response. Let me fix and put online an important piece of equipment without wasting time.

PS: another way to generate a variety of useful test tones is in Room EQ Wizard, which has a signal generator. Also free and open source, like Audacity.

Then you'll realize you can't hear above 18khz..
