    they, most likely, need to be inside the audio passband, maybe under 2 1/2 KHz or so and they need to be kind of split and non-harmonically related. Like... one in the upper hundreds towards 1 KHz and the other could be just over 2 KHz.

    Here is a video:

    Does it do the double tone that you were wanting?

    Let's see...

    "Key of Middle C" on a piano...

    On Sheet Music...

    On a Piano...

    upload_2020-11-23_19-45-17.png

    Note it's not A3 ....

    It's approximately ~262 Hz (Cycles per Second)
    Cyan color key is C4 (Or middle C)

    Go here for help on this
    https://en.wikipedia.org/wiki/C_(musical_note)

    Note the Amber - color key, A4 - is 440Hz.

    Ok, why the above music lesson?

    Most Vocals don't use much above 2kHz - 2,000 Hz - unless you want to make your voice sound like scratching fingernails on a chalkboard...

    Let the "overtones" take care of themselves, you just have to keep your voice in the correct pass band.

    So, A3 to about A5 (if you're a "tenor") Bass? Try A2 to A4 .

    So @kaos513 - If you can use both tones - simultaneously - please do so, just remember to run the attenuator to keep their Fundamentals - 1.4kHz, 2.8kHz and above - out - from skewing your tuning results.
