Abstract The variable length record method of spectral analysis is considered as a composite of perturbations of a simple harmonic analysis. By smoothing over near neighbours, the composite spectrum can be made to approach the true spectrum. Since the method is computationally expensive, a less costly technique of multiple interpolation is considered and shown to produce equivalent results. This method is suitable for examining the low frequency end of cli ma to logical spectra.
