The simplest technique I've had success with is to use FFT and then perform a Harmonic Product Spectrum. It is simple to implement and not very resource intensive, you just need to correctly downsample your result FFT and make products. The following question should also be useful: Detecting the fundamental frequency.

The motion pattern of a system oscillating at its natural frequency is called the normal mode (if all parts of the system move sinusoidally with that same frequency). If the … Ver más Free vibrations of an elastic body are called natural vibrations and occur at a frequency called the natural frequency.
