# Collaplex 音效 — 把链路固化装到 PipeWire(用户级)
#
#   链路: 全局音频(应用输出) -> collaplex_vsink(虚拟声卡)
#         -> 响度归一化(pipe DSP) -> collaplex_hrtf_in(双耳 HRTF + 房间混响) -> 数字输出
#
# 装什么:
#   $HOME/.local/bin/collaplex-loudness-norm            pipe 插件入口(指向本项目 dsp/)
#   $HOME/.config/pipewire/pipewire.conf.d/10-...conf   虚拟声卡 + 响度归一化
#   $HOME/.config/pipewire/pipewire.conf.d/20-...conf   HRTF 核心(接入 + 输出)
#
# 湿量: WET=0.3 环境变量覆盖(默认 0.3)
