Abstract
The present document relates to audio communication systems. In particular, the present document relates to the control of the level of audio signals within audio communication systems. A method for leveling a near-end audio signal () using a leveling gain () is described. The near-end audio signal () comprises a sequence of segments, wherein the sequence of segments comprises a current segment and one or more preceding segments. The method comprises determining a nuisance measure () which is indicative of an amount of aberrant voice activity within the sequence of segments of the near-end audio signal (); and determining the leveling gain () for the current segment of the near-end audio signal (), at least based on the leveling gain () for the one or more preceding segments of the near-end audio signal (), and by taking into account—according to a variable degree—an estimate of the level of the current segment of the near-end audio signal (); wherein the variable degree is dependent on the nuisance measure ().
