Method for improving the quality of an audio transmission via a packet-oriented communication network and communication system for implementing the method

摘要

The invention permits the improvement of the quality of an audio transmission in which audio data including samples of an audio signal are asynchronously transmitted in data packets via a packet-oriented communication network, such as a LAN. According to the invention, the audio data to be transmitted and/or already transmitted are digitally converted such that their sampling rate is altered and/or the duration of an audio signal represented by the audio data is modified while largely retaining its pitch. The conversion is performed based on a transmission situation currently detected, in such a manner that a quality of service of the audio transmission is optimized.
