In addition, in the embodiment of the present application, the audio that present video output scene is exported may include a type of
Audio also may include a plurality of types of audios.
If present video exports the audio of scene output, including a plurality of types of audios, then in target audio tunnel
Audio in, may include muli-sounds type.It is if transmitting the audio of muli-sounds type in target audio access, this is more
A sound type is used as target sound type, i.e. target sound type includes multiple sound types.For example, in certain game sound
When broadcasting, while the sound including the people and footsteps etc. in space passes simultaneously then in corresponding voice-frequency channel indoors
The sound of the defeated sound for having space type and voice type, using space type and voice type as target sound type.
When target sound type includes multiple sound types, its corresponding audio is obtained to multiple sound type respectively and is calculated
Method, also, handled by audio of the sound effect algorithms to corresponding sound type.For example, in target audio access, the sound of transmission
The audio b that frequency includes the audio a that sound type is A and sound type is B, then obtain the corresponding sound effect algorithms of sound type A
The corresponding audio point counting B1 of A1 and sound type B.Also, audio a is handled by sound effect algorithms A1, passes through sound
Type B 1 handles audio B.
In the embodiment of the present application, in target audio access, the time is different, the audio transmitted there may be variation,
Type belonging to audio may also be different.For example, game proceeds to different phase to the sound in Mr. Yu's scene of game, it may
Different sound is generated, different sound may belong to different sound types.Therefore, for identical audio output scene in mesh
It marks during transmitting audio in voice-frequency channel, electronics can in real time determine the audio transmitted in target audio access

For certain audios for needing to enhance spatial impression, the corresponding type parameter of space type can be added to it.Therefore,
When transmitting the audio with space type corresponding types parameter in target audio access, can be determined according to such shape parameter
The audio effect processing of spatial impression enhancing is carried out to the audio.Specifically, passing through target audio corresponding with the target sound type
Algorithm enhances the audio of the target audio tunnel, then can be, can be with to its audio by phase information
The spatial impression of performance is enhanced.
Specifically, in the actual environment, sound reaches human ear by different location, people's spatial impression can be given.For example, lesser
In spatial dimension, the sound that a sound source generates, partial sound reaches human ear, and partial sound is after the barrier reflection in space
Human ear is reached, direction and the time difference of sound is reached, hearer is enable to recognize the spatial impression in sound.
Inventor has found that different directions reach the sound of human ear, brain can be according to the phase of the sound received
The direction for the sound that position analysis receives and time delay.Since sound is to be propagated in the form of wave and eardrum is caused to shake
It is dynamic, therefore sound reaches when human ear is received by human ear and corresponds to certain phase.Brain analyzes the sound for reaching eardrum,
The information such as direction and the time that sound reaches are obtained by its phase.Therefore, for phase difference reach human ear sound,
By hearer's brains analysis, there can be spatial feeling to hearer with sound, increase spatial impression.
It therefore, in the embodiment of the present application, can be audio setting phase difference, to realize the audio of spatial impression enhancing.By

Audio replicated, to obtain and the former consistent audio copy of audio content.
Have dephased audio to broadcast to obtain, which is handled, there is it between former audio
Phase difference.Specifically, since sound is propagated in air in the form of wave, for period and the identical wave of amplitude, in difference
Time, phase is different.Therefore, can by audio copy relative to the former audio delay preset duration realize audio copy with
Phase difference between former audio, when audio which makes that treated plays, when the sound of generation reaches eardrum, former audio is corresponding
Phase phase corresponding from audio copy it is different, enhance spatial impression.
In the embodiment of the present application, the specific time span of preset duration does not limit, can be according to the sound gone for
Reinforcing effect is imitated, such as angle and distance information calculating acquisition between the sound for hearing auditor.Circular
It is referred to existing way, is repeated no more in the embodiment of the present application.
Since sound wave has periodically, in the embodiment of the present application, in order to certain phase difference, preset duration can be with
The multiple in period corresponding not equal to audio or period.In addition, canceling sound is instead resulted in completely in order to avoid phase difference,
Preset duration is also not equal to one of the half period of the corresponding sound wave of audio or the integral multiple plus thirty in the period period.
Optionally, since the time difference for reaching auditor is less than 35ms, and acoustic pressure difference is maintained within 10dB, two sound
The same sound can be acoustically considered to be.At this point, the directionality of direct sound wave can remain, it is considered as unique side of sound source
To.But due to the presence of the two acoustical phases difference, it virtually also can additionally enhance spatial impression.Therefore, if wanting to allow hearer by sound
Sound, which is considered as the same sound but, can experience spatial impression in audio, preset duration can be set smaller than 35ms when
Between.Alternatively, it is also possible to set acoustic pressure difference within 10dB for former audio and audio copy.If wanting that auditor is allowed to regard sound
For spatial impression caused by different sound, such as same sound reflects the sound repeatedly formed in a room, can also will preset
Time is set greater than 35ms, or acoustic pressure difference is arranged other than 10dB.
Optionally, in the embodiment of the present application, when carrying out audio enhancing, the audio that can be replicated in target audio access
Copy amount does not limit, and is also possible to two or more, also, is ok between different audio copies and former audio
The difference that phase difference is realized in certain delay is set, realizes multiple spatial impression.
Optionally, due to carrying phase information in the audio data of some audios, and in the audio data of some audios
Phase information may not be carried.Therefore, in the space for the audio for enhancing the target audio tunnel by phase information
Before sense, it can first judge in the audio of the target audio tunnel whether to include phase information.
And the audio for not carrying phase information, virtual phase information can be added for the audio, that is to say, that
Phase information is added in the audio data of the audio.The enhancing that audio is realized in processing is carried out by the phase information being added again.
In the embodiment of the present application, the audio for enhancing algorithm process by audio is passed through into the responses such as earphone, loudspeaker
