Abstract

The invention relates to a computer-implemented method for processing an audio signal, in particular including speech. The method comprises obtaining a recorded audio signal having a dedicated sampling rate, in particular above 22 kHz, whereas the recorded audio signal comprises a speech portion and a noise portion. A spectrogram is generated from the recorded audio signal and then applied to a processing chain of two subsequent denoiser processes. A first of the two subsequent denoiser processes is a machine-learning based denoiser process to provide a denoised spectrogram. The second of the two subsequent denoiser process is a denoiser process configured to remove stationary noise from a spectrogram applied to it.
