在Audio to Timecode Alignment窗口中应该填什么？
对于使用Dante和LTC over Audio的DAMS系统，系统的延时需要测量并且填写到“Audio to Timecode Alignment”的相应字段中，确保LTC能够精确同步。
使用ASIO时这些数值有预置，不过依然需要进行测试并且在需要时进行调整。
为了确定系统延时，轨道中播放一个“点”声音，录制到渲染器中，并通过Re-render录回到工作站中相邻的轨道。将音频波形放大，测量两个文件的开头的距离（以采样为单位）。
2-pop非常适合用于检测同步，不过任何不带有淡入的音频都是可以的。为了让测量更加精确，录制同步音频源时应该带有一些预录，并且在录回到工作站时使用相同的预录值。
What values should be entered in the Audio to Timecode Alignment window?
For Dolby Atmos Mastering Suite setups using Dante and LTC over audio, the system latency needs to be determined and the “Audio to Timecode Alignment” field set in order to ensure accurate synchronization to LTC.
This value is preset for setups using ASIO but should still be tested and adjusted as needed.
To determine system latency a “spotted” audio source is mastered to the renderer. The start time of an exported re-render imported into Pro Tools on an adjacent track is compared to the audio source start time by zooming in on the waveform and measuring the distance (in samples) from the start of the source to the start of the imported re-render.
Tone used as a synchronization 2-pop is suitable for this task but any audio can be used as long as there is no fade in. To make this task more accurate the sync audio source should be mastered with some pre-roll and spotted back to the session using the same value.
