1. A method of compressing digital signal data obtained from a signal, comprising:
receiving digital signal data associated with a signal and/or generating digital signal data based on a signal;
transforming the digital signal data into a transform domain, thereby generating transformed digital signal data, wherein a spectrogram of the digital signal is determined based on the transformed digital signal data;
determining at least one characteristic parameter based on the transformed digital signal data by an artificial intelligence circuit;
detecting and/or classifying at least one wanted signal portion based on the at least one characteristic parameter by the artificial intelligence circuit; and
storing only a subset of the digital signal data that is associated with the at least one wanted signal portion.
