[nrv-hams] Audio signal generator to borrow?

[J.C. Hassall]

Folks,
Does anyone have an audio signal generator I may borrow for a week?  I've
shown granddaughter Bea what her voice looks like and she was just blown
away.  Now I'd like to show her what the frequency components look like,
teach her about wavelength and amplitude, sine waves and stuff I haven't
thought of yet.  But I need an audio source.  I thought about programming
an Arduino but need a smooth sine wave, not a digitized wave.

Thank you!
