Abstract

Verfahren zur Audioübertragung, insbesondere Sprachübertragung, über ein paketbasiertes Telekommunikations- bzw. Datennetz, das eine senderseitige Kodierung und empfängerseitige Dekodierung von Audiodaten einschließt, wobei die Audiodaten zur Bitratenreduktion oder Bandbreitenerhöhung senderseitig vor der Kodierung einer Stauchung der Zeitbasis und/oder empfängerseitig nach der Dekodierung einer Dehnung der Zeitbasis unterzogen werden.A method for audio transmission, in particular voice transmission, via a packet-based telecommunications or data network, which includes a transmitter-side encoding and receiver-side decoding of audio data, wherein the audio data for bit rate reduction or bandwidth increase transmitter side before encoding a compression of the time base and / or receiver side after the decoding of a Elongation of the time base to be subjected.
