[0024] As mentioned above, with the continuous development of smart cockpit technology, the in-vehicle audio system has become a key part of in-vehicle infotainment in the smart cockpit. As users' demands for in-vehicle audio systems become more diversified and personalized, users will choose different in-vehicle audio system configurations according to their needs. At present, vehicles with different in-vehicle audio configurations use different versions of audio output software to output audio through speakers with different numbers or different amplifiers. However, it is costly to maintain and develop multiple different versions of audio output software.

[0025] An embodiment of the present application provides an audio output method, which obtains an audio file, parses the audio file, determines a target audio channel used by the audio file from an audio channel group, and controls at least one speaker to output the audio corresponding to the audio file according to the target audio channel, so as to output the audio corresponding to the audio file through a vehicle audio system. The audio output scheme in the embodiment of the present application can use at least some audio channels in the same audio channel group for different audio files, so as to output audio from speakers with different vehicle audio configurations. Compared with the prior art in which vehicles with different vehicle audio configurations use different versions of audio output software, vehicles with different vehicle audio configurations can use the same audio output software to achieve audio output, thereby reducing the development cost and maintenance difficulty of the audio software.

[0026] The audio output method provided by the present application is described below through embodiments.

[0027] Figure 1 is a flowchart of an audio output method provided in an embodiment of the present application, such as Figure 1 As shown, the audio output method includes the following steps 101 to 103:

[0028] Step 101: Obtain an audio file.

[0029] Audio files contain audio information for audio output. Vehicles with different car audio configurations can obtain different audio files. For example, when a vehicle with a low car audio configuration does not require stereo playback, it can obtain an audio file containing only mono audio information. When a vehicle with a high car audio configuration requires stereo playback of the sound source, it can obtain an audio file containing multi-channel audio information. Vehicles with the same car audio configuration can also obtain different audio files. These audio files contain different audio information and correspond to different audio output modes, such as surround sound mode, headrest mode, etc.

[0030] Step 102: parse the audio file and determine a target audio channel used by the audio file from an audio channel group, wherein the audio channel group includes a plurality of audio channels.

[0031] The audio file is parsed to obtain audio information contained in the audio file, wherein the audio information is used to indicate an audio channel to be used for the audio in the audio file, and a target audio channel used by the audio file is determined from an audio channel group according to the audio information contained in the audio file, wherein the target audio channel is used to indicate an input channel of the audio corresponding to the audio file in an audio digital signal processor (ADSP). In one example, an audio channel group may include 12 audio channels, and the target audio channel is at least part of the audio channels in the audio channel group.

[0032] Step 103: According to the target audio channel, control at least one speaker to output the audio corresponding to the audio file.

[0033] According to the target audio channel, the audio in the audio file is input into the ADSP, and the ADSP determines the speaker or the sounding mode of the speaker, or the sounding position of the speaker, etc. that outputs the audio corresponding to the audio file, and controls at least one speaker to output the audio corresponding to the audio file.

[0034] In an embodiment of the present application, an audio file is obtained, the audio file is parsed, a target audio channel used by the audio file is determined from an audio channel group, and according to the target audio channel, at least one speaker is controlled to output the audio corresponding to the audio file, so as to output the audio corresponding to the audio file through the vehicle audio system. The audio output scheme in the embodiment of the present application can use at least some audio channels in the same audio channel group for different audio files, so as to output audio from speakers with different vehicle audio configurations. Compared with the prior art in which vehicles with different vehicle audio configurations use different versions of audio output software, vehicles with different vehicle audio configurations can use the same audio output software to achieve audio output, thereby reducing the development cost and maintenance difficulty of the audio software.

[0035] In a possible implementation, when parsing an audio file and determining a target audio channel used by the audio file from an audio channel group, the audio file can be parsed to obtain multiple first audio streams of the audio file, and based on the multiple first audio streams, a target audio channel corresponding to each first audio stream can be determined from the audio channel group.

[0036] Parse the audio file to obtain multiple first audio streams contained in the audio file. The first audio stream is a sub-audio of the audio corresponding to the audio file, which can indicate the audio channel to be used in the audio input ADSP in the audio file. According to the multiple first audio streams contained in the audio file, determine the target audio channel corresponding to each first audio stream from the audio channel group, and each first audio stream corresponds to a target audio channel.

[0037] In an embodiment of the present application, an audio file is parsed to obtain multiple first audio streams in the audio file, and a target audio channel corresponding to each first audio stream is determined from an audio channel group based on the multiple first audio streams. Each first audio stream is input into the ADSP through the corresponding target audio channel to realize the input of audio corresponding to different audio files, thereby achieving compatibility of the same audio output software with audio corresponding to different audio files, so that the same audio output software can meet the vehicle audio output requirements of different vehicle audio configurations, thereby reducing the cost of software development.

[0038] In one possible implementation, if the audio corresponding to the audio file is multimedia, the audio file corresponds to a first number of target audio channels; if the audio corresponding to the audio file is non-multimedia, the audio file corresponds to a second number of target audio channels, wherein the second number is greater than or equal to the first number.

[0039] If the audio type corresponding to the audio file is multimedia, the audio file corresponds to a first number of target audio channels. In one example, an audio file with an audio type of multimedia can be designed according to the vehicle audio configuration. For example, the corresponding audio file of a vehicle with a low vehicle audio configuration may include only 2 target audio channels. In another example, the audio file corresponding to a vehicle with a high vehicle audio configuration may include 6, 8 or 12 target audio channels.

[0040] If the audio type corresponding to the audio file is non-multimedia, the audio file corresponds to a second number of target audio channels, where the second number of audio channels is 12, that is, 12 audio input channels are enabled when the audio corresponding to the non-media audio file is input to ADSP. When the first audio stream in the audio corresponding to the audio file is less than 12, only some audio channels have audio streams. In one example, when a vehicle with a low car audio configuration outputs non-multimedia audio without stereo requirements, there are only two first audio streams in the audio source file, corresponding to the front left channel and the front right channel. Therefore, when inputting ADSP, only the front left channel and the front right channel have audio streams, and other audio channels are enabled but there are no audio streams in the audio channels. In another example, when a vehicle with a high car audio configuration outputs non-multimedia audio, the first audio stream in the audio file can fill the 12 enabled audio channels.

[0041] It should be noted that in order to meet the needs of vehicle audio output of different car audio configurations, the vehicle multimedia audio channel group of different car audio configurations is determined according to the car audio configuration, for example, including 2, 6, 8 or 12 audio channels, and the non-multimedia audio channel group is uniformly determined to include 12 audio channels. In one example, the 5.1-configured car audio multimedia audio channel group includes 6 audio channels, and the non-multimedia audio channel group includes 12 audio channels. In another example, the 7.1-configured car audio multimedia audio channel group includes 8 audio channels, and the non-multimedia audio channel group includes 12 audio channels.

[0042] In an embodiment of the present application, if the audio corresponding to the audio file is multimedia, the audio file corresponds to a first number of target audio channels; if the audio corresponding to the audio file is non-multimedia, the audio file corresponds to a second number of target audio channels; multimedia audio can use audio files corresponding to different numbers of audio channels according to the vehicle audio configuration, thereby meeting the requirements of multimedia audio input of vehicles with different vehicle audio configurations; non-multimedia audio generally enables 12 audio channels, thereby achieving compatibility with non-multimedia audio output of vehicles with different vehicle audio configurations, and achieving audio input of audio files of different audio types through different audio channels; thereby achieving compatibility of the same audio output software solution with audio output of audio files of different audio types of vehicles with different vehicle audio configurations, thereby reducing the development cost of the audio output software.

[0043] In one possible implementation, when controlling at least one speaker to output audio corresponding to an audio file according to a target audio channel, a target sound channel can be determined according to a first audio stream and a target audio channel, and the first audio stream can be transmitted to the target sound channel through the target audio channel, so that a target speaker corresponding to the target sound channel outputs corresponding audio.

[0044] According to the first audio stream and the target audio channel, the target sound channel is determined. The target sound channel is an output channel in the ADSP. Different ADSP parameters are stored in the ADSP. The ADSP parameters are used to indicate the mapping relationship between the audio input channel and the audio output channel, that is, the mapping relationship between the target audio channel and the target sound channel. According to the mapping relationship between the target audio channel and the target sound channel indicated by the ADSP parameters, multiple first audio streams can be transmitted to the corresponding target sound channel through the target audio channel, so that the target speaker corresponding to the target sound channel outputs the corresponding audio.

[0045] It should be understood that the mapping relationship includes one-to-one, one-to-many, and many-to-one, that is, one target audio channel can be mapped to one target sound channel, one target audio channel can be mapped to multiple target sound channels, and multiple target audio channels can be mapped to one target sound channel. In one example, when there is no stereo requirement for the audio output, the front left channel audio in the target audio channel is mapped to the sound channel corresponding to the front left channel speaker, and the front right channel audio in the target audio channel is mapped to the sound channel corresponding to the front right channel speaker. In another example, the front left channel audio channel in the target audio channel can be mapped to the low-frequency, mid-frequency and high-frequency front left channel speaker sound channels. In another example, when the user selects the headrest mode, multiple target audio channels can be mapped to the sound channels corresponding to the two headrest speakers.

[0046] In an embodiment of the present application, a target sound channel is determined based on a first audio stream and a target audio channel, and the output of audio in different audio files in the ADSP is realized. The first audio stream is transmitted to the target sound channel through the target audio channel, so that the target speaker corresponding to the target sound channel outputs the corresponding audio, thereby realizing the output of audio in different audio files through the speaker. Therefore, the same audio output software solution is implemented to output audio of vehicles with different vehicle audio configurations, thereby reducing the development cost of the audio output software.

[0047] In one possible implementation, when making the target speaker corresponding to the target sound channel output the corresponding audio, the audio algorithm can be adjusted for the first audio stream to obtain a second audio stream, and the second audio stream can be transmitted to the target speaker corresponding to the target sound channel through the target sound channel, so that the target speaker outputs the audio corresponding to the second audio stream.

[0048] The audio algorithm in ADSP is used to adjust the first audio stream through the audio algorithm, such as volume adjustment, sound quality equalization, delay and / or mixing, to obtain the second audio stream, which is used to indicate the audio information of the audio output to the speaker in the audio file, and the second audio stream is transmitted to the target speaker corresponding to the target sound channel through the target sound channel, so that the target speaker outputs the audio corresponding to the second audio stream. Specifically, each sound channel in the target sound channel can correspond to one or more target speakers. In one example, there are six sound channels in a 5.1 channel system, and each sound channel corresponds to one of the six speakers of the 5.1 sound system. In another example, a bass channel can control multiple speakers for playing low-frequency effects to output bass audio.

[0049] In an embodiment of the present application, the audio algorithm in ADSP is used to adjust the first audio stream to obtain the second audio stream, thereby optimizing the audio quality. The second audio stream is transmitted to the target speaker corresponding to the target sound channel through the target sound channel, so that the target speaker outputs the audio corresponding to the second audio stream, thereby realizing the audio output of vehicles with different vehicle audio configurations and meeting the audio output requirements of vehicles with different vehicle audio configurations.

[0050] In a possible implementation, when parsing an audio file and determining a target audio channel used by the audio file from an audio channel group, the audio file may be parsed to determine the number of audio channels required for the audio file. If the number of audio channels required for the audio file is less than or equal to the number of audio channel groups, the audio channels required for the audio file are determined as target audio channels. If the number of audio channels required for the audio file is greater than the number of audio channel groups, each audio channel in the audio channel group is determined as a target audio channel.

[0051] Parse the audio file, obtain the audio stream information in the audio file, and determine the number of audio channels required to input the audio file into ADSP based on the audio stream information. If the number of audio channels required by the audio file is less than or equal to the number of audio channel groups, the audio channels required by the audio file are determined as target audio channels, that is, the number of audio channel groups meets the number of audio channels required by the audio file, and the audio channels required by the audio file in the audio channel group are determined as the channels for the audio stream in the audio file to be input into ADSP. If the number of audio channels required by the audio file is greater than the number of audio channel groups, each audio channel in the audio channel group is determined as a target The number of audio channels, that is, the number of audio channel groups, cannot meet the number of audio channels required by the audio file, and all audio channels in the audio channel group are determined as channels for inputting the audio stream in the audio file into ADSP. In one example, a vehicle audio channel group of a car audio configuration has 6 audio channels. If the user selects an audio file that needs to use less than or equal to 6 audio channels, the audio stream in the audio file is input into ADSP through the audio channels required by the audio file in the audio channel group. If the user selects an audio file that needs to use more than 6 audio channels, the 6 audio streams in the audio file are input into ADSP through the 6 audio channels in the audio channel group.

[0052] In an embodiment of the present application, an audio file is parsed to determine the number of audio channels required for the audio file. If the number of audio channels required for the audio file is less than or equal to the number of audio channel groups, the audio channels required for the audio file are determined as target audio channels. If the number of audio channels required for the audio file is greater than the number of audio channel groups, each audio channel in the audio channel group is determined as a target audio channel, thereby achieving the output of audio in different audio files for vehicles with different vehicle audio configurations, thereby achieving the same audio output software being compatible with different audio files for audio output, meeting the audio output requirements of vehicles with different vehicle audio configurations, and reducing the audio output software development cost.

[0058] In a possible implementation, the parsing unit 202 may further parse the audio file to obtain multiple first audio streams of the audio file, and determine, according to the multiple first audio streams, a target audio channel corresponding to each first audio stream from the audio channel group.

[0059] In one possible implementation, the parsing unit 202 may further, if the audio corresponding to the audio file is multimedia, the audio file corresponds to a first number of target audio channels; if the audio corresponding to the audio file is non-multimedia, the audio file corresponds to a second number of target audio channels, wherein the second number is greater than or equal to the first number.

[0060] In a possible implementation, the control unit 203 may also determine a target sound channel according to the first audio stream and the target audio channel, and transmit the first audio stream to the target sound channel through the target audio channel so that the target speaker corresponding to the target sound channel outputs the corresponding audio.

[0061] In a possible implementation, the control unit 203 may further perform an audio algorithm adjustment on the first audio stream to obtain a second audio stream, and transmit the second audio stream to a target speaker corresponding to the target sound channel through a target sound channel, so that the target speaker outputs the audio corresponding to the second audio stream.

[0062] In a possible implementation, the control unit 203 may further parse the audio file to determine the number of audio channels required for the audio file. If the number of audio channels required for the audio file is less than or equal to the number of audio channel groups, the audio channels required for the audio file are determined as target audio channels. If the number of audio channels required for the audio file is greater than the number of audio channel groups, each audio channel in the audio channel group is determined as a target audio channel.
