In audio acquisition applications, how to remove external environmental noise (such as voice, singing voice, etc. in broadcasting) has been a technical problem to be solved. Especially, when audio is played in the environment, if the audio acquisition device does not know the audio already played by the audio playing device, it will bring great difficulty to the work of removing noise (i.e. the audio played by the audio device). For example, when the vehicle-mounted device collects real environmental sound, the real environmental sound is influenced by a broadcast or other sounds being played in the vehicle, and the real external audio cannot be collected.
