Abstract
The invention claims a method for estimating the noise in the audio signal (102). for the energy value (174) for the audio signal (102) is estimated (S100) and converting the (S102) with the logarithm domain. based on the energy values of the transform (178) of the audio signal (102) noise level estimate (S104).
A method is described that estimates noise in an audio signal (102). An energy value (174) for the audio signal (102) is estimated (S100) and converted (S102) into the logarithmic domain. A noise level for the audio signal (102) is estimated (S104) based on the converted energy value (178).
