频谱图的参数上图是一个 flac 无损文件的频谱图，最上面是这个文件的外在参数，采样率 48kHz、24bit，横轴是时间，纵轴是声音的频率，不同的颜色代表着不同的响度，也就是音量，可以参考图上最右侧的色条；当音量小到 -120db 以下，颜色就是黑色的，表示几乎没有声音。

There are a couple ways mitigate this drawback, both of which are outside the scope of this article. One is “garbage collection”: pruning tombstones from CRDTs, which prevents you from merging states with any changes made before the tombstones were removed. Another is creating an efficient format to encode the data. You can also combine these methods. Research suggests that this can result in as little as 50% overhead compared to the “plain” data CRDTs: The Hard Parts A talk on the latest research on CRDTs, originally given at the Hydra distributed computing conference on 6 July 2020.References: https://martin.kleppmann.co... youtu.be/x7drE24geUw?t=3587 .
