Yes, you could use a tuning fork and mic to measure the tuning fork's frequency with this circuit, but you would need a pre amp for the microphone. There should be plenty of simple circuits for that online. I haven't worked much with audio amplification. Setting the frequency of musical instruments will have the same issues as the human voice. Frequency Counter Results depend on your device and its hardware. If you just want to know the frequency of a sound with harmonics (e.g. mucial instrument), a FFT based app such as keuwlsofts spectrum analyser, harmonicity meter or guitar tuner will be better. This app can provide more accurate frequency measurement for single frequency input signals.
