Abstract: An audio processing method and an audio processing apparatus are described. A mono-channel audio signal is transformed into a plurality of first subband signals. Proportions of a desired component and a noise component are estimated in each of the subband signals. Second subband signals corresponding respectively to a plurality of channels are generated from each of the first subband signals. Each of the second subband signals comprises a first component and a second component obtained by assigning a spatial hearing property and a perceptual hearing property different from the spatial hearing property to the desired component and the noise component in the corresponding first subband signal respectively, based on a multi-dimensional auditory presentation method. The second subband signals are transformed into signals for rendering with the multi-dimensional auditory presentation method. By assigning different hearing properties to desired sound and noise, the intelligibility of the audio signal can be improved.

Abstract: A method for audio signal processing is provided. The method includes acquiring a first set of metadata associated with consumption of an audio signal by a target user, acquiring a second set of metadata associated with a set of reference users and generating, at least partially based on the first and second sets of metadata, a recommended configuration of at least one parameter for the target user, the at least one parameter being for use in the consumption of the audio signal. Corresponding apparatus and computer program product are also disclosed.
