Abstract: A method and apparatus for detecting and removing transient noise in an audio signal, in particular an audio signal containing speech by one or more of the following, determining a plurality of sound labels associated with the audio signal using an SED (Sound Event Detection) module, wherein the SED module comprises a machine learning model configured to divide the audio signal into a number of SED time windows, determining, one or more sound labels associated with each of the number of SED time windows, wherein the one or more sound labels are chosen from a predefined set of sound labels, detecting, based on the plurality of determined sound labels, transient noise in the audio signal, and removing, based on the detected transient noise, transient noise from the audio signal to generate a denoised signal.

Abstract: A computer-implemented method for transforming audio input data into audio output data is provided. The method comprises receiving audio input data, providing background sound data by separating speech components from the audio input data by using a speech removal module, determining acoustic scene data, linked to an acoustic scene matching the background sound data, by using an acoustic scene classifier module, selecting a specialized noise reduction module based on the acoustic scene data, and processing the audio input data by using the specialized noise reduction module such that the audio output data is generated.
