Embodiments of the present invention provide a method for identifying radio music, a vehicle-mounted system, a vehicle, and a computer-readable storage medium, wherein the method is applied to a vehicle-mounted system, and the vehicle-mounted system includes an application processor AP, an echo cancellation AEC module, and a radio module , the AP runs a radio application, and the method includes: the radio application controls the AEC module to acquire radio music data from the radio module; the radio application acquires radio music data from the AEC module; the radio The application identifies the station music data. The embodiment of the present invention solves the problem that the APP cannot obtain the music data of the radio station, so that the radio application can identify the music data of the radio station to obtain music information.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a music recognition method, a vehicle-mounted system, a vehicle and a computer-readable storage medium. Background technique [0002] With the development of vehicle entertainment, more and more users like to listen to music during driving, and when users listen to favorite music, they often wish to know the title of the music. [0003] Car radio is a way to listen to music in vehicles. Taking FM radio as an example, there is an FM module in the vehicle's control unit CDU (Conversion&Distribution Unit), which can be a dedicated FM function chip, or integrated in the audio codec device Codec The internal FM subsystem only needs to have FM function. The FM module receives the FM signal through the FM antenna, and demodulates the received signal. The demodulated signal is amplified by the power amplifier PA (Power Amplifier), and finally played out from the speaker. [0004] T...
