Apparatus, method and corresponding computer program for generating an error concealment signal using an adaptive noise estimation |
摘要 |
An apparatus for generating an error concealment signal, comprises: an LPC representation generator (100) for generating a replacement LPC representation; an LPC synthesizer (106, 108) for filtering a codebook information using the replacement LPC representation; and a noise estimator (206) for estimating a noise estimate during a reception of good audio frames, wherein the noise estimate depends on the good audio frames representation generator (100) is configured to use the noise estimate estimated by the noise estimator (206) in generating the replacement LPC representation. |
