Patent ID: 8750530

Claim:
A method for processing audio data, wherein at least one filter spectrum is derived from at least one audio signal, for each of the filter spectra, the deriving comprising: transforming the at least one audio signal into a spectral representation, defining the filter spectrum as an interpolation curve of the spectral representation which expresses the formant character of the at least one audio signal, the processing of the audio data comprising at least: providing to at least one first filter source audio data representing a first audio signal with first spectral properties, for removing from the source audio data the formant character of the first audio signal, where the at least one first filter is based on at least one first filter spectrum derived from the first audio signal, and providing the filtered source audio data to at least one second filter, where the at least one second filter is based on at least one second filter spectrum derived from at least one target audio signal with at least one second spectral properties, for impressing on the filtered source audio data the formant character of the at least one target audio signal.
