Abstract
Apparatuses, arrangements and methods therein for generation of comfort noise are disclosed. In short, the solution relates to exploiting the spatial coherence of multiple input audio channels in order to generate high quality multi channel comfort noise.
Claims9
A method, performed by an encoder, for supporting generation of comfort noise for two audio channels at a decoder, the method comprising:
- determining a spatial coherence between two audio signals on respective input audio channels;
- and
- signaling information about the spatial coherence between the audio signals to the decoder, for generation of comfort noise at the decoder.
An encoder, the encoder comprising at least one processor and a non-transitory memory containing instructions which, when executed by the at least one processor, cause the encoder to:
- determine a spatial coherence between two audio signals on respective input audio channels;
- and
- signal information about the spatial coherence between the audio signals to a decoder, for generation of comfort noise at the decoder.
