AB  - GHA is a frequency analysis originally proposed by N.wiener in 1930. He aimed to analyze stochastic signals utilizing harmonic frequency analysis and clarified that any signal can be represented by almost periodic function whose frequency components are in inharmonic relationship. In 1993 Dr. Hirata proposed an inharmonic frequency analysis applicable to audio signal processing and it became called as “GHA”. The authors have been engaged in its improvements and utilizations, and reported several applications. Among them the authors have reported intensive noise reduction to damaged SP records in the past convention. In this paper, the principle of GHA and its fundamental characteristics will be explained together with its application to noise reduction in comparison with conventional spectral subtraction method.
