As shown in fig. 2, fig. 2 is a schematic flowchart of an audio transmission method according to an embodiment of the present application. When the first device is used for multi-device networking, the remote second device is usually used as an audio playing output device, so that resource sharing between the first device and the remote second device is achieved, wherein the second device can be a virtual device. In this scenario, an audio stream is first generated at a first device and transmitted to a Hardware Abstraction Layer (HAL). Then, the HAL performs audio coding compression on the audio stream or uses Pulse Code Modulation (PCM) to transmit the audio stream to the remote second device through the network, and after receiving the audio stream, the remote second device outputs the audio stream through the audio playing device of the second device and performs audio playing, thereby completing the virtual sharing of the audio from the first device to the audio playing of the remote second device.

As also shown in fig. 3, fig. 3 is a schematic flowchart of another audio transmission method provided in the embodiment of the present application. The application program of the first device plays different types of audio (such as call audio, alert tone, ringtone, music, etc.), the Android system plays audio streams to the HAL layer, before sending to the HAL, the Android system resamples the different audio streams to convert the different audio streams into audio streams with fixed audio parameters (such as sampling rate, sampling precision, channel number), the HAL layer receives the audio streams with the fixed audio parameters, then performs audio coding compression on the converted audio streams or processes the audio streams into a PCM format, transmits the PCM format to the remote second device through the network, and the remote second device receives the audio streams and then outputs and plays the audio streams through the audio playing device of the device.

In a multi-device networking scenario, when an HAL layer is used to virtualize an audio stream to a remote device for playing, an Android system of a first device can only process the audio stream by using fixed audio parameters (such as sampling rate, sampling accuracy, and channel number), and when a remote second device plays different audio types (such as call audio, alert tone, ringtone, music, and the like), can only use the fixed audio parameters. Since distributed remote devices are very different, many low-cost second devices do not support audio resampling capability, for example, low-end internet of things (IOT) devices only support the most basic playing function, depending on the hardware cost. As another example, for a particular audio type (e.g., call audio, alert tone, ring tone, music, etc.), only fixed audio parameters may be used for playback (such as older Linux car machines). In this case, the audio playing of the remote second device may not be compatible, which may cause an audio playing effect in a multi-device networking scenario, and affect the user experience. In order to solve the above technical problem, embodiments of the present application provide the following solutions.

As shown in fig. 4, fig. 4 is a schematic flowchart of an audio playing method provided in an embodiment of the present application. The steps in the embodiments of the present application include:

s401, the first device obtains the audio capability of the second device.

In a specific implementation, in a multi-device networking scenario, a first device may obtain an audio capability of a second device through a discovery connection protocol. The audio capability comprises at least one of a target audio parameter, an audio coding and decoding capability and a networking connection mode. The target audio parameters may include a sampling rate, a number of channels, a sampling precision, and the like. The audio codec capability may include the second device supporting audio codec or the second device not supporting audio codec. For example, the audio codec may be Advanced Audio Coding (AAC) or sound coding (OPUS). The networking connection mode may include a wired connection and a wireless connection.

Further, the audio capability may include a target audio parameter corresponding to each of the plurality of audio types. The plurality of audio types includes, among others, alert tones, call audio, and media audio. For example, the audio capabilities may include the following information: for the prompt tone, the sampling rate is 16K, the sampling precision is 16bit, and a single sound channel is formed; for the call audio, the sampling rate is 8K, the sampling precision is 16bit, and a single sound channel is formed; for media audio, sample rate 48K, sample precision 16bit, binaural.

Optionally, after establishing a connection with the second device, if it is required to use the remote second device as an audio playing output device, the first device may send a request message to the second device, where the request message is used to request the audio capability of the second device. And after receiving the request message of the first device, the second device feeds back the audio capability of the second device to the first device. If the first device does not receive the audio capability within the preset time range, the first device may resend the request message to the second device until receiving the audio capability fed back by the second device.

S402, the first device converts the first audio stream into a second audio stream according to the audio capacity. The method comprises the following several optional modes:

in a first alternative, the audio capabilities comprise target audio parameters; and the first equipment converts the first audio stream into a second audio stream corresponding to the target audio parameter. For example, if the first device uses audio parameters of sampling rate 48K, sampling precision 16bit, two channels, and the target audio parameters fed back by the second device include sampling rate 16K, sampling precision 16bit, single channel. Therefore, the first audio stream with 48K sampling rate and 16bit sampling precision and two channels needs to be converted into a second audio stream with 16K sampling precision and 16bit and single channel.

In a second alternative, the audio capability includes a target audio parameter corresponding to each of a plurality of audio types; the first device acquires the audio type of the first audio stream; converting the first audio stream into the second audio stream according to the audio type.

For example, if the first device uses audio parameters of sampling rate 48K, sampling precision 16bit, two channels, the second device supports alert tones (sampling rate 16K, sampling precision 16bit, mono), talk audio (sampling rate 48K, sampling precision 16bit, mono), media audio (sampling rate 48K, sampling precision 16bit, two channels). For the cue tone, the sampling rate of 48K, the sampling precision of 16bit, and the first audio stream of the two channels may be resampled to obtain the second audio stream of the single channel with the sampling rate of 16K and the sampling precision of 16 bit. For the call audio, resampling the sampling rate 48K, the sampling precision 16bit and the first audio stream of the double-track to obtain a second audio stream of the single-track with the sampling rate 48K and the sampling precision 16 bit. For media audio, the first audio stream does not need to be resampled, since the audio parameters used by the first device are the same as the target audio parameters supported by the second device, and the second audio stream is the same as the first audio stream.

In a third alternative, the audio capability comprises an audio codec capability; when the second device supports audio coding and decoding, the first device converts the first audio stream into the second audio stream in a compression coding mode; the first device converts the first audio stream into the second audio stream by pulse code modulation when the second device does not support audio codec. For example, the second device supports AAC codec, the first device may AAC encode the first audio stream to obtain a second audio stream, and the second device ACC decodes the second audio stream after receiving the second audio stream.

In a fourth optional mode, the audio capability includes a networking connection mode between the first device and the second device; when the networking connection mode is wireless connection (for example, WIFI wireless mode 2.4G), the first device converts the first audio stream into the second audio stream through a compression coding mode. In the wireless connection mode, the data flow is reduced by a compression coding mode, so that the wireless bandwidth resources are effectively utilized. When the networking connection mode is wired connection, the first device converts the first audio stream into the second audio stream through pulse code modulation. Under the wired connection mode, the device has sufficient bandwidth, and the audio quality is guaranteed through pulse code modulation.

In a fourth optional manner, the audio capability includes an audio codec capability and a networking connection manner. When the second device supports audio coding and decoding and the networking connection mode is wireless connection, the first device converts the first audio stream into the second audio stream in a compression coding mode; and when the second equipment does not support audio coding and decoding and the networking connection mode is wireless connection, the first equipment converts the first audio stream into the second audio stream through pulse code modulation. When the networking connection mode is wired connection, the first audio stream can be converted into the second audio stream through pulse code modulation regardless of whether the second device supports audio coding and decoding.

In a fifth optional manner, the audio capability includes a target audio parameter, an audio encoding and decoding capability, and a networking connection manner. The first device may convert the first audio stream into the second audio stream according to the target audio parameter, the audio codec capability, and the networking connection method. For example, if the first device uses audio parameters of sampling rate 48K, sampling precision 16bit, two channels, and the target audio parameters fed back by the second device include sampling rate 16K, sampling precision 16bit, single channel. And the second device supports audio coding and decoding, and the networking connection mode between the first device and the second device is wireless connection. The first device may resample the first audio stream with a sampling rate of 48K, a sampling precision of 16bit, and a binaural, and ACC encode to obtain a second audio stream with a sampling precision of 16K, 16bit, and a monophonic.

It should be noted that the target audio parameter, the audio encoding and decoding capability, and the networking connection mode may be combined arbitrarily, and the first device may convert the first audio stream into the second audio stream according to the audio capability obtained by any combination. For specific implementation, reference may be made to the above embodiments, which are not described herein again.

Optionally, the audio capability includes a resampling capability, and if the second device does not support audio resampling, the first device performs the step of converting the first audio stream into the second audio stream according to the audio capability. If the second device supports audio resampling, the first device may send the first audio stream to the second device without processing the first audio stream. Optionally, if the second device supports audio resampling, the first device may also convert the first audio stream into a second audio stream, and send the second audio stream to the second device for audio playing.

S403, the first device sends the second audio stream to the second device, where the second audio stream is used for audio playing by the second device.

In a specific implementation, in a process of sending a second audio stream to a second device by a first device, the second device may perform audio playing on the received second audio stream until the second audio stream is completely played. It should be noted that, if the second audio stream sent by the first device is an encoded audio stream, after receiving the second audio stream, the second device needs to decode the second audio stream and then perform audio playing.

In the embodiment of the application, under a multi-device networking scene, the requirement for audio playing of a remote second device can be reduced, so that the multi-device networking device is more diversified, the second device can be accessed by supporting basic discovery connection and basic audio playing capability, and audio playing can be completed under the condition that the second device does not support audio resampling or audio coding and decoding capability. Moreover, the computational power of the first device can be fully utilized, and the audio stream is processed according to the differentiated audio capability of the second device, so that the processed audio stream can meet the playing requirement of the second device, and the quality and the effect of the audio are improved.
