APPARATUS, METHOD AND COMPUTER PROGRAMM FOR AVOIDING CLIPPING ARTEFACTS
摘要
An audio encoding apparatus includes an encoder for encoding a time segment of an input audio signal to be encoded to obtain a corresponding encoded signal segment. The audio encoding apparatus further includes a decoder for decoding the encoded signal segment to obtain a re-decoded signal segment. A clipping detector is provided for analyzing the re-decoded signal segment with respect to at least one of an actual signal clipping or an perceptible signal clipping and for generating a corresponding clipping alert. The encoder is further configured to again encode the time segment of the audio signal with at least one modified encoding parameter resulting in a reduced clipping probability in response to the clipping alert.
