Adaptive comfort noise parameter determination

A method for generating a comfort noise (CN) side-gain parameter, the method comprising:

• receiving an audio input, wherein the audio input comprises multiple channels;
• detecting, with a Voice Activity Detector (VAD), a current inactive segment in the audio input;
• and
• as a result of detecting, with the VAD, the current inactive segment in the audio input, calculating a CN side-gain parameter SG(b) for a frequency band b, wherein
• the CN side-gain parameter SG(b) is calculated based at least in part on the current inactive segment and a previous inactive segment.

A method for generating comfort noise (CN), the method comprising

• receiving a CN side-gain parameter SG(b) for a frequency band b;
• and
• generating the comfort noise based on the CN side-gain parameter SG(b), wherein the CN side-gain parameter is generated by:
• detecting, with a Voice Activity Detector (VAD), a current inactive segment in an audio input comprising multiple channels,
• as a result of detecting, with the VAD, the current inactive segment in the audio input, calculating the CN side-gain parameter SG(b) for a frequency band b, wherein
• the CN side-gain parameter SG(b) is calculated based at least in part on the current inactive segment and a previous inactive segment.

A node for generating a comfort noise (CN) side-gain parameter, the node comprising:

• a receiving unit configured to receive an audio input, wherein the audio input comprises multiple channels;
• a detecting unit configured to detect, with a Voice Activity Detector (VAD), a current inactive segment in the audio input;
• a calculating unit configured to calculate, as a result of detecting, with the VAD, the current inactive segment in the audio input, a CN side-gain parameter SG(b) for a frequency band b, wherein
• the CN side-gain parameter SG(b) is calculated based at least in part on the current inactive segment and a previous inactive segment.
