Apparatus and method for processing an audio signal for speech enhancement using a feature extraction |
| abstract |
An apparatus for processing an audio signal to obtain control information for a speech enhancement filter (12) comprises a feature extractor (14) for extracting at least one feature per frequency band of a plurality of frequency bands of a short-time spectral representation of a plurality of short-time spectral representations, wherein the at least one feature represents a spectral shape of the short-time spectral representation in the frequency band of the plurality of frequency bands. The apparatus additionally comprises a feature combiner (15) for combining the at least one feature for each frequency band using combination parameters to obtain the control information for the speech enhancement filter for a time portion of the audio signal. The feature combiner can use a neural network regression method, which is based on combination parameters determined in a training phase for the neural network. |
