common use case
Conduct your own audio experiments.
Test your hearing: On average, humans hear frequencies between 20 Hz and 20,000 Hz, but hearing deteriorates with age, especially for frequencies close to ultrasound.
Find and try to mask the frequency of your tinnitus.
Removes water from phone speakers by generating sound waves in a specific frequency range.
Play and export randomly generated sound effects. Export requires Android 6.0+.
Understand how your audio setup handles frequency sweeps from very low frequencies to near ultrasound.
note
The application generates frequencies from 1 Hz (infrasound) to 22000 Hz (ultrasound) and supports decimal values (eg 7.83 Hz).
The available waveforms for generating signals are: sine, square, triangle and sawtooth.
Several studies have found that ultrasound is not an effective method of repelling mosquitoes. If you still want to use this app as a mosquito repellent, you should know that anti-mosquito apps only produce ultrasonic or near ultrasonic waves (between 15000 Hz and 22000 Hz).
Keep in mind that the resulting tones can be very annoying and irritating to your surroundings. Always use this application responsibly. Also, keep the audio volume low to avoid damaging your hearing or audio equipment. If you raise the volume to better hear very low frequencies, don't forget to lower the volume before playing higher frequencies: the perceived volume of a tone depends on its frequency.
