audiorecord 多个audiosource audition多个音轨整合 在多轨会话中进行音频剪辑编辑,一般先要确定好时间标尺。比如,要进行精准对齐、拼接等操作时,一般选择“小节与节拍”;要改变整体持续时间时,一般选择“十进制(mm:ss.ddd)”。 音轨上的音频剪辑本质是原始音频文件的实例。因此,更改了音频剪辑是不会改变原始素材的。
AudioService又会将AudioPolicy的配置信息注册到AudioPolicyService中,供AudioPolicyService进行播放设备路由选择时使用。 AudioPolicy是播放设备路由策略的扩展接口,当有人创建了AudioPolicy对象,并注册给AudioPolicyService时,AudioPolicyService就会优先使用这个路由策略,而不会使用默认的硬编码策略。AudioPolicy相关的源码是在/...
