Wait for the terminal.

1 is a flowchart of an audio output control method according to an embodiment of the present application. As shown in FIG. 1 , an audio output control method in this embodiment of the present application includes:

S101. Receive an audio stream of a call voice in a voice call mode.

The voice call mode may include a voice call for a telephone call, a voice call of an instant messaging tool (such as WeChat, qq, etc.), an instant voice call in the game, and the like. When in the voice call mode, the audio stream of the call voice is received from the corresponding communication network or the Internet.

S102. Set an attribute information of an audio stream of the call voice when creating a sound track on the audio stream of the received call voice.

The attribute information includes a first stream type identifier, and the first stream type identifier is a stream type identifier of an audio stream of the call voice.

The audio stream of the call voice received in S101 needs to be created with an audio track (AudioTrack). When the voice track of the call voice is created, the stream type identifier of the call voice is set. For example, the stream type identifier is AudioSystem.STREAM_VOICE_CALL, etc., for identifying Call voice.

S103. Output, according to the attribute information of the audio stream to be played, the audio stream whose attribute information meets the preset condition is output through the first audio output device, and output the other audio stream through the second audio output device.

The audio stream whose attribute information meets the preset condition is an audio stream having the identifier of the first stream type.

The audio stream having the first stream type identifier (eg, the stream type identifier is AudioSystem.STREAM_VOICE_CALL) is output through the first audio output device according to the stream type identifier of the audio stream to be played. Accordingly, other audio streams that do not have the first stream type identification are output through the second audio output device.

The first audio output device may be a headset, including a wireless headset such as a wired headset and a Bluetooth headset. The second audio output device includes an audio playback device (a speaker, a speaker or a loudspeaker, etc.) on the terminal, such as a speaker of a television set, a loudspeaker of a mobile phone or a pad, etc., or may be output to other through a connection line. On the terminal's PA equipment.

For example, on a smart TV terminal device with a voice call, the game controller is connected to the TV through a High Definition Multimedia Interface (HDMI) data line, and the game controller has a sound output port, and the earphone can be inserted. In this output port.

In the non-voice call mode, sounds (eg, game sounds, movie sounds) are output from the TV's HDMI and played out using the TV's speakers. When the user connects to the gamepad and plugs in the headphones, the sound is output from the headphones.

In the voice call mode, when a voice track is first created for the received call voice, attribute information such as the stream type of the voice (audio stream of the call voice) and the sampling rate of the voice is set as the only audio stream of the call voice. The identification is further divided according to the identifiers, and the call voice and other background sounds are distinguished from the audio stream to be played, the call voice is output from the earphone, and other sounds are output from the HDMI of the TV, and played out by the speaker of the TV, thereby Give users a better product experience, can meet the needs of users while talking on the game, or meet the needs of users while watching video while talking.

Optionally, the attribute information of the audio stream of the call voice set in S102 may further include a first sound sampling rate, where the first sound sampling rate is a sampling rate of the audio stream of the call voice.

The sampling rate is how many sound samples are collected by the computer per second. It is the quality standard that describes the sound quality and tone of the sound file and measures the sound card and sound file. For the audio stream output by the headphone device, the first sound sampling rate may be used for sampling, and for other audio streams output by the sound amplification device, the second sound sampling rate may be used for sampling, wherein the first sound sampling rate and The second sound sampling rate is a different sampling rate, determined by the hardware or software of the terminal (such as TV).

Therefore, when the audio track is created for the audio stream of the received call voice, the sampling rate of the audio stream of the call voice can also be set to be the first sound sampling rate. Then, in S103, the audio stream whose attribute information meets the preset condition is an audio stream having the first stream type identifier and the first sound sampling rate.

In this way, by setting the attribute information such as the stream type identifier of the audio stream of the call voice to perform the audio output shunting, the call voice and the background music can be effectively outputted to different port outputs, so that the user can simultaneously play the game or the audio and video. Make a voice call, play a game (or watch a video) while making a voice call, and the user experience is good.
