摘　　要：以近期音乐节直播项目为例,阐述为提高音乐节在互联网播出端的听觉体验效果,在不改变广播电台播总控系统播出链路的前提下,通过使用在Max/Msp编程平台中创建的程序,将舞台音源与3D麦克风拾取的环境信号进行叠加、渲染,产生双耳立体声信号(Binaural Audio),并将该信号送至互联网播出端口进行直播的方式方法。结果表明,该方法在一定程度上有效还原了现场声音环境,提升了用户使用耳机在互联网端口收听音乐节时的沉浸式听觉体验。Taking the recent live music festival project as an example, this paper expounds in order to improve the Internet auditory experience and without changing the broadcast playing and controlling system, a Max/Msp program was built to create binaural audio mixes which blended the individual microphones signals from the stage with ambient signals captured using a 3D microphone settled at audiences’ area, and the resulting binaural audio was steamed live online. The results show that the method can effectively restore the music festival sound environment to a certain extent, and increase the user’s immersive auditory experience when listening to music festival through the Internet port with headphones.
