Method for processing audio data of e.g. guitar, involves removing spectral property from spectrum of audio data, and impressing another spectral property on audio data, where another spectrum is formed corresponding to latter property

摘要

The method involves removing a spectral property from a spectrum of audio data. Another spectral property is impressed on the audio data, where another spectrum is formed corresponding to the latter spectral property. A minimal-phase filter is generated with cepstral-transformation of a linear-phase filter. The spectrums are determined by analyzing the audio data by interpolating maxima of a spectral representation of the audio data. A power intensity spectrum is generated from the spectral representation of the audio data before the interpolation. Independent claims are also included for the following: (1) an arrangement for processing audio data, comprising a chip (2) a computer program comprising a set of instructions to perform a method for processing audio data.
