Apparatus, method or computer program for processing an information signal using a compression of a dynamic range

An apparatus for processing an information signal, comprises: a feature extractor (100) for extracting a set of features from the information signal, wherein the feature extractor (100) comprises: a raw feature calculator (110) for calculating raw feature results, each raw feature result having at least two raw feature components; and a raw feature compressor (120) for performing a compression of a dynamic range to the at least two raw feature components to obtain at least two compressed raw feature components for each raw feature result, wherein the set of features comprises the compressed raw feature components; and a signal processor (600) for processing the set of features to obtain the processed information signal, wherein the information signal comprises an audio signal, an image signal, or a radar signal.
