采样率是 96kHz，看频谱音频信号已经顶满 48KHz，但是很明显的是，20 多 K 以上部分是静音和噪音部分（30 K 以上），所以这个歌曲的有效信号其实就是 21KHz 以下。但它并没有出现高频很明显的截断，高频截止得比较自然，说明这个文件就是一个真的 CD 音质无损音乐强行升频出来的，升频后并没有带来任何的音质提升，而是引入了大量的高频噪音。

These days I prefer to do the building of containers myself. Creating an OCI image as an artifact gives me flexibility over where things run and opens up all kinds of options. Today it might be a simple docker-compose stack on a single VPS, tomorrow it could be scaled out across a Kubernetes cluster via a Helm chart or operator. The container part is straight-foward as Rails creates a Dockerfile in each new application which is pretty much prod-ready. I usually tweak it slightly by adopting a “meta” container approach where I move some of the stuff that changes infrequently like installing gems, running apt-get and so on into an image that the main Dockerfile uses as a base.
