摘要： The present document relates to audio signal processing, in particular to an apparatus and a corresponding method for improving an audio signal of an FM stereo radio receiver. In particular, the present document relates to a method and system for reliably detecting the quality of a received FM stereo radio signal and for selecting an appropriate processing based on the detected quality. An apparatus (20) configured to estimate the quality of a received multi-channel FM radio signal is described. The received multi¬ channel FM radio signal is representable as a mid signal and a side signal, and the side signal is indicative of a difference between a left signal and a right signal. The apparatus (20) comprises a power determination unit configured to determine (101) a power of the mid signal, referred to as mid power, and a power of the side signal, referred to as side power; a ratio determination unit configured to determine (102) a ratio of the mid power and the side power, thereby yielding a mid-to-side ratio; and a quality determination unit configured to determine (105) a quality indicator of the received FM radio signal based at least on the mid-to-side ratio.

摘要： Described is a method of training a neural-network-based system for determining an indication of an audio quality of an audio input. The method includes obtaining, as input, at least one training set comprising audio samples. The audio samples include audio samples of a first type and audio samples of a second type, wherein each of the first type of audio samples is labelled with information indicative of a respective predetermined audio quality metric, and wherein each of the second type of audio samples is labelled with information indicative of a respective audio quality metric relative to that of a reference audio sample. The method further includes: inputting the training set to the neural-network-based system; and iteratively training the system to predict the respective label information of the audio samples in the training set.
