Abstract:
An apparatus for decoding an encoded audio signal to obtain a reconstructed audio signal is provided. The apparatus includes a receiving interface, a delay buffer and a sample processor for processing the selected audio signal samples to obtain reconstructed audio signal samples of the reconstructed audio signal. The sample selector is configured to select, if a current frame is received by the receiving interface and if the current frame being received by the receiving interface is not corrupted, the plurality of selected audio signal samples from the audio signal samples being stored in the delay buffer depending on a pitch lag information being included by the current frame.

Claim (Index 12):
A method for decoding an encoded audio signal to acquire a reconstructed audio signal, wherein the method comprises:\n receiving a plurality of frames, decoding the plurality of frames by conducting an inverse modified discrete cosine transform to acquire audio signal samples of the decoded audio signal, conducting long-term prediction by\n storing the audio signal samples of the decoded audio signal, \n selecting a plurality of selected audio signal samples from the audio signal samples being stored in a delay buffer, and \n processing the selected audio signal samples to acquire reconstructed audio signal samples of the reconstructed audio signal, \n wherein, if a current frame is received and if the current frame being received is not corrupted, selecting the plurality of selected audio signal samples from the audio signal samples being stored in the delay buffer is conducted depending on a pitch lag information being comprised by the current frame, and wherein, if the current frame is not received or if the current frame being received is corrupted, selecting the plurality of selected audio signal samples from the audio signal samples being stored in the delay buffer is conducted depending on a pitch lag information being comprised by another frame being received previously, wherein the method further comprises rescaling the selected audio signal samples depending on a modified gain, wherein the modified gain is defined according to the formula:\n gain=gain_past*damping; \n wherein gain is the modified gain, wherein gain_past is set to gain after gain has been calculated, and wherein damping is a real value with 0\u2264damping\u22641.
