Abstract
A method for extracting at least one audio object from at least two audio input signals, each of which contains the audio object. The second audio input signal is syncronized with the first audio input signal while obtaining a synchronized second audio input signal. The audio object is extracted by applying at least one trained model to the first audio signal and to the synchronized second audio input signal. The audio object is outputted. Further, the step of synchronizing the second audio input signal with the first audio input signal includes the steps of: generating audio signals; analytically calculating a correlation between the audio signals; optimizing the correlation vector; and determining the synchronized second audio input signal using the optimized correlation vector.
