摘要

high quality pitch correction using audio processing a processed representation of an audio signal having a frame sequence is generated by sampling the audio signal within a first and a second frame of the frame sequence, c) second frame following the first frame, sampling using information from a pitch contour of the first and second frames to obtain a first shown representation. the audio signal is sampled within the second and third frames, the third frame following the second frame in the frame sequence. sampling uses information on the pitch frame of the second frame and information on a pitch outline of the third frame to obtain a second sampled representation. the first scaling window is obtained from the first sampled representation and a second scaling window is obtained from the second sampled representation, the scaling windows depending on the samplings applied to obtain the first sampled representations or the second sampled representation.
