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。

What I don't buy is the claim I keep seeing that telemetry is useless and doesn't actually help. I can only speak to Firefox telemetry, but I presume the lesson generalizes. Telemetry has paid for itself many times over on the technical side - stability, security, performance, and rollout safety. If you trust the publisher and want to help them improve the thing you use every day, turning on telemetry is the lowest-effort way to do it. If you don't trust them, or just don't want to... cool.
