InfraUltra Sound Generator

The human range of hearing is fairly limited, but there are many reasons one might wish to generate sounds that are above and below the audible threshold, whether to test out equipment or observe their effects.

InfraUltra Sound Generator is a very simple piece of software that enables you to generate sound waves at a number of set frequencies that fall outside the human audible spectrum. It offers a limited set of features, but it is very easy to use.

Humans can’t normally hear sounds that have a frequency below 20 Hz or above 20 KHz, but they can still be detected using specialized devices, and many other animals can perceive them. Using this utility, you can play several samples recorded at frequencies below 20 Hz and above 20 KHz.

Since you can’t hear these sounds, it would be difficult to tell if the program is functioning correctly. Fortunately, you can check this by clicking the Test button to play a sound file that is audible.

Sadly, a fairly limited number of frequencies can be played, as only 4 samples are available for infrasounds and 8 for ultrasounds. If you want to be able to fine-tune the frequency and select an exact value, this program may not be the right choice.

The user interface leaves a lot to be desired, as it features a very outdated and simplistic design. Also, it would have been great if users were able to select frequencies without entering the values, as there aren’t that many options to choose from.

Overall, InfraUltra Sound Generator can be useful if you are looking for a simple way to play sounds that are outside the human range of hearing, but it is a rudimentary application at best. Nevertheless, it can be set up in no time, and it is very easy to use.
