I've just done something similar for a wavetable synth - I did an FFT, found the lowest bin with a lot of energy in it, then back to the time domain, autocorrelating the start of the next cycle with the beginning of the current, with sub-sample precision. It works well enough for my application but isn't tested in real-time.
