IMPROVED MAGNITUDE RESPONSE AND TEMPORAL ALIGNMENT IN PHASE VOCODER BASED BANDWIDTH EXTENSION FOR AUDIO SIGNALS |
| 摘要 |
An apparatus for generating a bandwidth extended audio signal from an input signal, comprises a patch generator for generating one or more patch signals from the input signal, wherein the patch generator is configured for performing a time stretching (1800, 1808) of subband signals from an analysis filterbank, and wherein the patch generator further comprises a phase adjuster (1806) for adjusting phases of the subband signals using a filterbank-channel dependent phase correction. |
