Method and system for maintaining trajectory length of pre-rendered spatial audio

The invention relates to a method and a system for maintaining track length of pre-rendered spatial audio. A method performed by a programmed processor of an audio system, the method comprising: receiving an audio track having a track length; generating a binaural audio version of the audio track, the binaural audio version having an extended track length; performing an attenuation operation on the binaural audio version to gradually lower a signal level of the binaural audio version below a signal threshold level along the extended track length at a time corresponding to an end time of the track length of the audio track; and store the binaural audio version having the track length of the track in memory for later transmission to an audio playback device for driving one or more speakers. 本公开涉及"用于维持预渲染空间音频的轨迹长度的方法和系统。"一种由音频系统的已编程处理器执行的方法，该方法包括：接收具有轨道长度的音轨；产生音轨的双耳音频版本，该双耳音频版本具有延伸轨道长度；对该双耳音频版本执行衰减操作，以沿该延伸轨道长度在对应于该音轨的该轨道长度的结束时间的时间将该双耳音频版本的信号水平逐渐降低到低于信号阈值水平；并将具有该音轨的该轨道长度的该双耳音频版本存储在存储器中以供稍后传输到音频回放设备以用于驱动一个或多个扬声器。
