耳机 EQ： LINUX 用什么玩 EQ？滤波器设置文件有没有样板？

LINUX 可以用 Pulseeffects 玩 EQ. 它有 29/30 段均衡（您自己数一下），基本上绝大部分场景都可以适用。所以在 LINUX 下面，您不必去找 EQUALIZER APO。

关于滤波器设置文件，一开始俺也走了弯路。通过 flatpak 安装了Pulseeffects，所以出乎预料，Pulseeffects 用户自定义的 EQ 设置被系统（用 JSON）存在一个令人难以琢磨的地方。

俺用 find / -name "xxxxxxxxxx-my-EQ-setting-012345" -mtime -1 找了几遍以后都没找到。最后，用 grep -inr "xxxxxxxxxx-my-EQ-setting-012345" ./ 在用户目录里面找出来是存在这文件里：

./.var/app/com.github.wwmm.pulseeffects/config/glib-2.0/settings/keyfile:158:last-used-preset='xxxxxxxxxx-my-EQ-setting-012345'

文件大小是 12 KB 左右。
网上还有人发现是在这里：

~/.var/app/com.github.wwmm.pulseeffects/config/PulseEffects/output/EQ.json

[root@localhost ~]# dnf -y install pulseeffects

后来俺用 YUM / DNF 安装的 Pulseeffects，配置文件的所在就比较能预料了。在这里：

~/.config/PulseEffects/output/

举例：

[wenxue@localhost ~]$ ls ~/.config/PulseEffects/output/4dollarTOhd800s.json  
/home/wenxue/.config/PulseEffects/output/4dollarTOhd800s.json

好吧，就当是笔记。网上有 PulseEffects 相关文档：

JSON（JavaScript Object Notation，JavaScript对象表示法）

是一种由道格拉斯·克罗克福特构想和设计、轻量级的数据交换语言，该语言以易于让人阅读的文字为基础，用来传输由属性值或者序列性的值组成的数据对象。尽管JSON是JavaScript的一个子集，但JSON是独立于语言的文本格式，并且采用了类似于C语言家族的一些习惯。

[root@localhost ~]# ls -la /home/wenxue/.config/PulseEffects/output

麦文学：LINUX 的 EQ： Pulseeffects 用户自定义的 EQ 设置存在什么地方？zhuanlan.zhihu.com

俺最近用得比较多的是一个四块钱（$3.99 ）的耳机， EQ 到 HD800S，听得不亦乐乎。已经不太碰那些昂贵的耳机了。

这个耳机的滤波器设置文件留在这里供大家参考。

[wenxue@localhost ~]$ cat ~/.config/PulseEffects/output/4dollarTOhd800s.json

都是手打的，万一对您有帮助敬请点点赞/赞赏。多谢大家。

基本上您把上面这个代码筺里面的东西存成 XXXXX.json, 然后放进隐藏文件夹（子目录）
