Audio effective applicator and audio effective grant program

摘要

P To provide a sound effect imparting device and a sound effect imparting PROGRAM capable of performing various sound conversion. PSOLUTION: A FFT part 2 analyzes the frequency of an input sound to determine spectrum distribution area including local peaks respectively. A spectrum deformation part 4 varies spectrum intensities of the respective spectrum distribution areas according to spectrum intensity variation tables stored in various tables 5. At this time and the degree of effect can be adjusted with parameters from a parameter specification part 6. The spectrum deformed by a spectrum deformation part 4 is converted by an IFFT part 7 into time areas and which are put together again and output. Values of the parameters may be varied according to the frequency of a spectrum distribution area. PCOPYRIGHT: (C)2006 and JPO& NCIPI
