Abstract:
An audio communication endpoint receives a bitstream containing spectral components representing spectral content of an audio signal, wherein the spectral components relate to a first range extending up to a first break frequency, above which any spectral components are unassigned. The endpoint adapts the received bitstream in accordance with a second range extending up to a second break frequency by removing moving spectral components or adding neutral-valued spectral components relating to a range between the first and second break frequencies. The endpoint then attenuates spectral content in a neighbourhood of the least of the first and second break frequencies for thereby achieving a gradual spectral decay. After this, reconstructing the audio signal is reconstructed by an inverse transform operating on spectral components relating to said second range in the adapted and attenuated received bitstream. At small computational expense, the endpoint may to adapt to different sample rates in received bitstreams.

Claim (Index 2):
The audio communication server of  claim 1 , wherein the mixer is further configured to:\n receive, from each audio communication endpoint, an output break frequency defining a frequency range on which the audio communication endpoint operates to reconstruct an audio signal encoded by an outgoing bitstream; and output a bitstream containing spectral components relating only to a frequency range extending up to an mixer break frequency being less than or equal to the least of the output break frequencies received from the audio communication endpoints.
