  • Apparatus, method and computer program for manipulating an audio signal comprising a transient event
    Patent number: 9230557
    Abstract: An apparatus for manipulating an audio signal comprising a transient event has a transient signal replacer configured to replace a transient signal portion, comprising the transient event of the audio signal, with a replacement signal portion adapted to signal energy characteristics of one or more transient signal portions of the audio signal, or to signal energy characteristics of the transient signal portion, to obtain a transient-reduced audio signal. The apparatus also has a signal processor configured to process the transient-reduced audio signal to obtain a processed version of the transient-reduced audio signal. The apparatus also has a transient-signal-re-inserter configured to combine the processed version of the transient-reduced audio signal with a transient signal representing, in an original or processed form, a transient content of the transient signal portion.

  • APPARATUS FOR ENCODING AND DECODING
    Publication number: 20100027625
    Abstract: An apparatus for encoding a sequence of samples of an audio signal, with each sample within the sequence having an original position, includes a sorter for sorting the samples depending on their sizes, in order to obtain a sorted sequence of samples, with each sample having a sorting position within the sorted sequence. Furthermore, the apparatus has an encoder for encoding the sorted samples and information on a relation between the original and sorting positions of the samples.
