Claim Text:
1. A decoder for decoding an encoded audio signal comprising: an input interface for processing the encoded audio signal to acquire a noise filling measure and encoded audio data; a decoder/re-quantizer for generating re-quantized data; a signal analyzer for retrieving information, whether a time frame of the audio data comprises harmonic or speech characteristic; and a noise filler for generating noise filling audio data, wherein the noise filler is configured to generate noise filling data in response to the noise filling measure and the harmonic or speech characteristic of the audio data; and a processor for processing the re-quantized data and the noise filling audio data to acquire a decoded audio signal; wherein the encoded audio signal comprises data indicating, whether the time frame of the audio data comprises a harmonic or speech characteristic, and wherein the signal analyzer is configured for analyzing the encoded audio signal to retrieve a data indicating, whether the time frame of the audio data comprises a harmonic or speech characteristic; wherein the data is an indication that the time portion has been subjected to a time warping processing, and wherein the processor comprises a time dewarper for time dewarping an audio signal derived from noise filling data and re-quantized data.
