Stream implementations can and do ignore backpressure; and some spec-defined features explicitly break backpressure. tee(), for instance, creates two branches from a single stream. If one branch reads faster than the other, data accumulates in an internal buffer with no limit. A fast consumer can cause unbounded memory growth while the slow consumer catches up — and there's no way to configure this or opt out beyond canceling the slower branch.

我发现我保存的大量 96kHz 和 192KHz 的音乐,都是普通的 CD 音乐强行升频的,感觉这个目前是高解析度音频的重灾区。当然不是所有这种音频的频谱都和上面一样,但是明显的特征是 21K 处有明显的边界,再以上的部分要么是全是静音,要么是静音和噪音的混合体,可能和使用的升频算法不一样导致的。
