Generate multiple tones at the same time, it's free and easy to use.

Multiple Tone Generator

This multiple tone generator allows you to enter any number of frequencies which can then be played simultaneously. The tones can be one of the following waveforms: sine, square, sawtooth and triangle.

Additionally, the volume and panning (left/right) can be adjusted independently for each tone, using the sliders provided in the table below.

Use the On/Off toggle switch to play/pause the tone, and the "Add a tone" button at the bottom of the table allows you to add any number of additional tones.

Please always make sure headphones/speakers are set to a low volume to avoid damage to hearing or equipment.
