摘要
本文设计实现了一款安卓平台下的基于双耳技术的VR音频直播系统,系统分为电脑端及Android端两个平台,平台之间采用Socket进行实时通信。在电脑端采用DirectSound进行声卡录音,模拟实时采集声源的过程;在Android端,通过头相关传输函数(Head Related Transfer Function,HRTF)插值算法进行目标声场信息的添加、播放,实现VR音频。该直播系统仅需一对耳机就能极大地提高用户的听觉体验,具有应用价值。
This paper designs and implements a VR audio live broadcast system based on binaural technology on Android platform,which is divided into two platforms:computer and Android.Socket is used for real-time communication between platforms.In the computer end,DirectSound is used to record sound cards and simulate the process of real-time acquisition of sound sources.In the Android end,through the Head-related Transfer Function(HRTF)interpolation algorithm for the addition and playback of the target sound field information,implement VR audio.The live broadcast system requires only a pair of headphones to greatly improve the user’s hearing experience and has application value.
