Abstract

The invention discloses an audio simulation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining at least two filters, and enabling different filters to represent different influence factors of an audio signal collected by a feedback microphone of an earphone when the earphone is worn; acquiring an original audio signal; and at least two filters are utilized to sequentially carry out at least two times of filtering processing on the original audio signal, and a simulation audio signal collected by a feedback microphone when the earphone is worn is generated. Through the above mode, the audio signal simulation method and the audio signal simulation device can enable the simulated audio signal to better conform to the real situation.

Description

technical field [0001] The present application relates to the technical field of signal processing, in particular to an audio simulation method, device, electronic equipment and storage medium. Background technique [0002] At present, for the training of the noise reduction model at the headphone feedback microphone, a large amount of training data is required. The existing training data collection generally adopts two ideas, one of which is to record a large number of speech and noise signals with headphones worn by different real people, and the other is to simulate a large number of speech signals by using data augmentation methods. For the former, a lot of data recording costs need to be invested and the recorded data can hardly be reused, while for the latter, it is impossible to cover the signal changes under different usage conditions of the headphones. Contents of the invention [0003] The technical problem mainly solved by this application is to provide an audi...
