Abstract:
1. An apparatus, comprising: a payload extraction block configured to extract coded digitised analogue signals from a digital network, wherein the extracted coded digitised analogue signals comprise at least in part parameterised coded digitised analogue signals; a first processor configured to process the extracted parameterised coded digitised analogue signals in a parameter domain with functions suitable to enhance a quality of the extracted parameterised coded digitised analogue signals; a second processor configured to process at least part of the extracted coded digitised analogue signals in a linear domain with functions suitable to enhance a quality of the extracted coded digitised analogue signals; a payload insertion block configured to insert the processed coded digitised analogue signals into the digital network; and an analyzer configured to determine a quality improvement of the digitised analogue signals resulting from a processing of the extracted parameterised coded digitised analogue signals in the parameter domain and from a processing of the extracted coded digitised analogue signals in the linear domain, and to determine which processing is capable of providing a better quality improvement, wherein the payload insertion block is further configured to insert at least the coded digitised analogue signals processed by the first processor or the second processor which lead to the quality improvement back into the digital network.
