Abstract (en)
[origin: WO2021105574A1] The invention relates to a method and device for processing an audio signal, for example a signal received by a vehicle (103) and converted in a tuner (104). To that end, the audio signal is sampled in order to obtain a vector of values of amplitudes each associated with a sample of the signal. The input vector is passed through a plurality of convolutional layers of a neural network in order to obtain, as output, a classification of the audio signal, a class representative of a noise level being assigned to the audio signal.
