Improvement of Cylindrical Record Reduction Utilizing Inharmonic Frequency Analysis GHA

Cylindrical records were important sound media around the beginning of 20th century, and a lot of historical recordings were made by using them. We have engaged in the research of Cylindrical record reproduction and noise-reduction of damaged SP records utilizing inharmonic frequency analysis of GHA(Generalized Harmonic Analysis). Surface noise of Cylindrical records are more serious than SP record, so we challenged its noise reduction by modifying GHA noise-reduction.
