Leakage is a problem in nearly all aspects of signal processing,
especially when the FFT is involved. Leakage takes the form of wide frequency
spikes due to a ``spilling over'' of information across frequency bins and
occurs most often when the sampling frequency is not an integer multiple of the
base frequency. The leakage correction method presented here substantially
reduces this problem. The method resamples the original time domain data within
specified limits. A frequency error measurement is taken for each sampling rate
within the defined limits. The minimum frequency error is recorded along with
the fundamental frequency of the
