<p>Encoding (2) an audio signal (A) is provided, wherein basic waveforms in the audio signal (A) are determined (200), a noise component (S) is obtained (21) from the audio signal (A) by subtracting (21) the basic waveforms from the audio signal (A), a spectrum of the noise component (S) is modeled (22) by determining auto regressive and moving average parameters (pi,qi), and the auto regressive and the moving average parameters (pi,qi) are included (23) in an encoded audio signal (A ) together with waveform parameters (Ci) representing the basic waveforms.</p> |
