Background playback is not possible due to firefox extension permission limitations. However, if the tab that the extension was started on is left playing in the background and not minimised, the tone can continue playing underneath another window.

With the Frequency Audio Tone Generator, you can experiment with different frequencies, create ference tones, test audio equipment, generate calming sounds for relaxation and meditation or test your hearing range.
