Abstract:
The invention provides an audio encoder including a combination of a linear predictive coding filter having a plurality of linear predictive coding coefficients and a time-frequency converter, wherein the combination is configured to filter and to convert a frame of the audio signal into a frequency domain in order to output a spectrum based on the frame and on the linear predictive coding coefficients; a low frequency emphasizer configured to calculate a processed spectrum based on the spectrum, wherein spectral lines of the processed spectrum representing a lower frequency than a reference spectral line are emphasized; and a control device configured to control the calculation of the processed spectrum by the low frequency emphasizer depending on the linear predictive coding coefficients of the linear predictive coding filter.

Claim (Index 4):
Audio encoder according to  claim 1 , wherein the control device comprises a spectral analyzer configured to estimate a spectral representation of the linear predictive coding coefficients, a minimum-maximum analyzer configured to estimate a minimum of the spectral representation and a maximum of the spectral representation below a further reference spectral line and an emphasis factor calculator configured to calculate spectral line emphasis factors for calculating the spectral lines of the processed spectrum representing a lower frequency than the reference spectral line based on the minimum and on the maximum, wherein the spectral lines of the processed spectrum are emphasized by applying the spectral line emphasis factors to spectral lines of the spectrum of the filtered frame.
