FineTune 1.5.0 macOS 音频调控 原生轻量级多应用音量路由 + ISO标准响度补偿
你是否厌倦了每次调高会议软件音量，却把背景音乐炸得震耳欲聋？又或者想把游戏音频直送客厅功放、而通知声只走笔记本扬声器——却被macOS死死卡在“全系统统一音量”的牢笼里？别再妥协了：FineTune 就是为你打破这道墙的开源利器。
它不靠系统级权限硬闯，而是以原生菜单栏小工具的姿态悄然驻留——零后台进程、无内存拖累、安装即用。但就是这个纤薄身板，赋予你前所未有的音频主权：每个正在发声的应用，都在它的窗口里清晰列队；滑动一下，独立调节音量；点开下拉，秒切输出设备——USB DAC、AirPlay扬声器、蓝牙耳机……任你自由编排。所有设置自动记住，下次启动无缝延续。
更聪明的是，它懂你的耳朵。新版1.5.0首发集成ISO 226:2023等响度曲线算法，开启「响度补偿」后，系统会实时感知你当前的设备类型与应用音量层级，动态增强被掩蔽的低频与高频——深夜调低总音量时，人声依然饱满清晰；会议室音量适中时，提示音穿透力不减分毫。这一切，只需一个开关，静默生效。
不止于路由与补偿：内置10段专业均衡器支持按设备保存自定义预设（命名、编辑、一键删除），新增「警报音量直控」让你彻底摆脱系统设置跳转；对不支持硬件音量调节的USB DAC，它还能智能接管软件层音量滑块，杜绝抖动与断续；就连多显示器环境下的DDC音量控件错位、外接耳机漏掉EQ等顽疾，这次全被精准修复。
没有花哨弹窗，没有学习成本——它就安静待在菜单栏，像呼吸一样自然。当你第一次把Zoom音频推给会议室音响、把Slack提示音缩到最小却不消失、在30%音量下仍听清播客里的吉他泛音时，你会明白：这不是又一个功能堆砌的工具，而是Mac音频体验本该有的样子。

Loudness Compensation Equalization:Fletcher-Munson correction — At low volumes, human hearing loses sensitivity to bass and treble. FineTune now applies frequency-dependent EQ based on ISO 226:2023 equal-loudness contours to compensate, driven by your device and per-app volumeReal-time loudness equalization — Measures signal loudness using K-weighted (ITU-R BS.1770) RMS and applies wideband gain with a soft-knee compressor to keep perceived loudness near a targetBoth features behind a single toggle in settings, disabled by default
Alert Volume:
Control macOS alert and notification volume directly from FineTune settingsLive sync with System Settings via periodic polling
Software Device Volume:Volume control for output devices that don't support hardware volume (e.g., some USB DACs)Opt-in via Settings — off by default to avoid conflicts with hardware volume
