Fig. 2 is a schematic flow chart of an audio transmission method according to an embodiment of the present application, as shown in fig. 2. When the first device is used for multi-device networking, a remote second device is generally 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 (hardware abstraction layer, HAL). The HAL then performs audio encoding compression or uses pulse code modulation (pulse code modulation, PCM) on the audio stream, the audio stream is transmitted to a remote second device through a network, and after the remote second device receives the audio stream, the audio stream is output through an audio playing device of the second device and played, so that the virtualized sharing from the audio of the first device to the audio playing of the remote second device is completed.

As further shown in fig. 3, fig. 3 is a schematic flow chart of another audio transmission method according to an embodiment of the present application. The application program of the first device plays different types of audio (such as call audio, prompt tones, ringtones, music and the like), the Android system plays audio streams to the HAL layer, before sending the audio streams to the HAL layer, the Android system resamples and converts the different audio streams into audio streams with fixed audio parameters (such as sampling rate, sampling precision and channel number), after receiving the audio streams with the fixed audio parameters, the HAL layer compresses or processes the audio encoding of the converted audio streams into a PCM format, the audio streams are transmitted to the second device at the far end through a network, and after receiving the audio streams, the second device at the far end outputs and plays the audio streams through the audio playing device of the device.

In a multi-device networking scenario, when the HAL layer is used to virtualize the audio stream to be played on a remote device, the Android system of the first device can only process the audio stream by adopting fixed audio parameters (such as sampling rate, sampling precision and channel number), and when the second device at the remote device plays different audio types (such as call audio, prompt tone, ringtone and music), the Android system of the first device can only adopt the fixed audio parameters. Because of the large difference between distributed remote devices, many low-cost second devices do not support audio resampling capability, such as low-end internet of things (internet of things, IOT) devices, and only support the most basic playback function due to the requirement of hardware cost. As another example, for a particular audio type (e.g., talk audio, alert tones, ring tones, music, etc.), only fixed audio parameters can be used for playback (e.g., old Linux car sets). In this case, the audio playing of the remote second device may not be compatible, resulting in an audio playing effect in a multi-device networking scenario, affecting the user experience. In order to solve the technical problems, the embodiment of the application provides the following solutions.

Fig. 4 is a schematic flow chart of an audio playing method according to an embodiment of the present application. The steps in the embodiment of the application comprise:

S401, the first device acquires the audio capability of the second device.

In a specific implementation, in a multi-device networking scenario, a first device may acquire 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 encoding and decoding capability and a networking connection mode. The target audio parameters may include, among other things, sampling rate, number of channels, sampling accuracy, etc. 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 (advanced audio coding, AAC) or sound coding (OPUS). The networking connection mode can comprise wired connection and wireless connection.

Further, the audio capability may include a target audio parameter corresponding to each of a plurality of audio types. Wherein the plurality of audio types includes alert tones, talk audio, and media audio. For example, the audio capability may include the following information: for the prompt tone, the sampling rate is 16K, the sampling precision is 16bit, and the single sound channel is realized; for call audio, the sampling rate is 8K, the sampling precision is 16bit, and the audio is mono; for media audio, the sampling rate is 48K, the sampling precision is 16bit, and the two channels are used.

Alternatively, the first device may, after establishing a connection with the second device, if it is required to use the remote second device as an audio playback output device, send a request message to the second device, where the request message is used to request audio capabilities of the second device. 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 can send a request message to the second device again 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 capability. Including the following several alternatives:

a first alternative, the audio capability comprises a target audio parameter; the first device converts the first audio stream into a second audio stream corresponding to the target audio parameter. For example, if the audio parameters used by the first device are sample rate 48K, sample precision 16bit, two channels, and the target audio parameters fed back by the second device include sample rate 16K, sample precision 16bit, mono. It is therefore necessary to convert the first audio stream of the two channels at a sampling rate of 48K with a sampling precision of 16bit into the second audio stream of the two channels at a sampling precision of 16K with a single channel.

The second alternative way is that the audio capability comprises a target audio parameter corresponding to each audio type in a plurality of audio types; the first device obtains the audio type of the first audio stream; and converting the first audio stream into the second audio stream according to the audio type.

For example, if the audio parameters used by the first device are sample rate 48K, sample precision 16bit, binaural, the second device supports alert tones (sample rate 16K, sample precision 16bit, mono), talk audio (sample rate 48K, sample precision 16bit, mono), media audio (sample rate 48K, sample precision 16bit, binaural). For the alert tone, the first audio stream with the sampling rate of 48K, the sampling precision of 16bit and the two channels can be resampled to obtain the second audio stream with the sampling rate of 16K, the sampling precision of 16bit and the single channel. And for call audio, resampling the first audio stream with the sampling rate of 48K, the sampling precision of 16bit and the double channels to obtain the second audio stream with the sampling rate of 48K, the sampling precision of 16bit and the single channels. For media audio, the second audio stream is identical to the first audio stream because the audio parameters used by the first device are identical to the target audio parameters supported by the second device without resampling the first audio stream.

A third alternative, the audio capabilities include audio codec capabilities; when the second device supports audio encoding and decoding, the first device converts the first audio stream into the second audio stream in a compression encoding mode; when the second device does not support audio codec, the first device converts the first audio stream into the second audio stream through pulse code modulation. 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 may ACC decode the second audio stream after receiving the second audio stream.

A fourth alternative way, the audio capability includes a networking connection way between the first device and the second device; when the networking connection mode is wireless connection (for example, 2.4G in WIFI wireless mode), the first device converts the first audio stream into the second audio stream through a compression coding mode. And in the wireless connection mode, the data flow is reduced by a compression coding mode, so that the wireless bandwidth resource is effectively utilized. And when the networking connection mode is wire connection, the first equipment converts the first audio stream into the second audio stream through pulse code modulation. Under the wired connection mode, the system has sufficient bandwidth, and ensures the audio quality through pulse code modulation.

The fourth alternative way, the audio capability includes an audio codec capability and a networking connection way. When the second device supports audio encoding and decoding and the networking connection mode is wireless connection, the first device converts the first audio stream into the second audio stream through a compression coding mode; when the second device does not support audio encoding and decoding and the networking connection mode is wireless connection, the first device converts the first audio stream into the second audio stream through pulse code modulation. When the networking connection is a wired connection, the first audio stream may be converted into the second audio stream through pulse code modulation, regardless of whether the second device supports audio codec.

A fifth alternative way, the audio capability includes a target audio parameter, an audio codec capability, and a networking connection way. 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. For example, if the audio parameters used by the first device are sample rate 48K, sample precision 16bit, two channels, and the target audio parameters fed back by the second device include sample rate 16K, sample precision 16bit, mono. And the second device supports audio encoding and decoding, and the networking connection mode between the first device and the second device is wireless connection. The first device may resample the sample rate 48K, sample precision 16bit, dual channel first audio stream and ACC encode to obtain a second resulting 16K, sample precision 16bit, single channel second audio stream.

It should be noted that the target audio parameter, the audio encoding and decoding capability and the networking connection mode may be arbitrarily combined, and the first device may convert the first audio stream into the second audio stream according to the audio capability obtained by arbitrary combination. Reference may be made to the above embodiments for specific implementation, and details are not repeated here.

Optionally, the audio capability includes a resampling capability, and 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 does not support audio resampling. 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 playback.

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

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

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