Generate Online Tone EASY.
Here you can input your desired tone frequency and press play. The output tone will be a pure tone sine wave sampled at a rate of 44 Khz. Tone can be stopped when the stop button is pressed.
Tone Generator can play in four different waveforms. It can be Sine, Square, Sawtooth and Triangle. You can choose between any of them, by pressing the waveform that you would like to generate.
Please make sure the headphones or speakers are set to a low volume before playing the sound in order to avoid any damages to hearing or sound equipment.
Online Tone Generator is compatible with the most modern browsers like the latest versions of Chrome, Firefox, Safari . If there is no output sound please consider to update or change your browser before trying again. If this is not possible, you can download and save a 10 second WAV file that can be played at any time on any equipment.
You can also increment the frequency of the frequency tone by clicking in the generator's input box, and pressing and holding the up or down arrow on your keyboard. This will result in a frequency increase/decrease by 1Hz at a time. If you hold the shift key at the same time, the frequency will change by plus or minus 10Hz at a time instead.
Now you can share specific tones with others using simple links. If you want to share a link for a frequency of 621Hz, simply type the following into your address bar: http://onlinetone.net?freq=621. The number at the end of the URL represents the frequency so simply change this to whatever frequency you want.
A similar principle also applies for pre-selecting a waveform. For example, to pre-select the square wave, simply use the link http://onlinetone.net?waveform=square. For the other types, change the word "square", with "sine", "sawtooth" or "triangle".
