Step S4: the ear-loop application of the application layer module 300 bypasses the audio subsystem of the Android Framework layer to directly call the audio HAL interface to obtain the dry audio data, so that the time delay caused by transmission and processing of the audio stream at Android Framework when the audio stream goes up to the application layer is greatly shortened.
Step S5: the singing application can directly acquire the dry audio data from the interface of the ear-return application, and corresponding business logic such as scoring, recording and the like is realized by utilizing the acquired voice audio stream.
Step S6: and the singing application simultaneously sends an accompaniment audio stream of the singing song to the ear-returning application in real time, and the reverberation effect of the human voice dry sound is realized by using a reverberation algorithm in the ear-returning application, so that wet sound frequency data are obtained.
Step S7: the ear-return application calls the audio HAL interface to send the accompaniment audio data and the wet audio data of the song to the signal processing module 200 for mixing, and the operation bypasses the audio subsystem in the Android, so that the time delay caused by transmission and processing of the audio stream at Android Framework when the audio stream is down to the driver is greatly shortened.
Step S8: after being mixed and processed in the signal processing module 200, the wet sound audio data and the accompaniment audio data are transmitted to the power amplifier module 400 through digital audio interfaces such as TDM, and the power amplifier module 400 drives the vehicle-mounted loudspeaker to play.
According to the entertainment system of the vehicle, the cost can be reduced through the built-in microphone, the human voice audio data of the person in the vehicle captured by the built-in microphone is preprocessed, human life enhancement and noise reduction are carried out, dry voice audio data are obtained, the dry voice audio data are reverberated through a preset reverberation algorithm, wet voice audio data are obtained, the wet voice audio data and accompaniment audio data are mixed to generate entertainment audio data, the use of the entertainment function in the vehicle is achieved, and the dry voice audio data, the wet voice audio data and the entertainment audio data can be used for reducing data transmission delay through an audio HAL interface, so that the use experience of a user is improved.
