Ultra Beeper is a freeware waveform sound generator that can create beeps, morse code and even hearing tests.

Ultra Beeper is more of a toy than anything else.

Beeps - You can create beeps with 5 pitches from low to ultra and even custom. A slider allows you to set the exact Hertz.

Morse code - Type in anything you like and play it with varying speeds or pitches.

Insects - The author also claims you can even scare away insects, but that's a little out of our realm of expertise. You decide.

If you need to make annoying beeps, Ultra Beeper is your app.
