Abstract:
In this contribution, current developments in packet-based HD-voice communication are summarized. Moreover, the, usually problematic, issue of interoperability with the already installed infrastructure is addressed. Therefore, several algorithmic approaches—including embedded coding, receiver- or network-based parameter estimation, and steganographic parameter transmission — are discussed based on the practically relevant example of parametric bandwidth extension for speech and audio signals. Index Terms — speech coding, speech transmission, wideband, super-wideband, bandwidth extension
