安装和使用
Windows 系统
# 安装Python依赖 pip install pycaw pyaudio numpy # 运行脚本 python auto_volume.py
Mac/Linux 系统
# 安装依赖 pip install pyaudio numpy # 运行脚本 python auto_volume.py # Linux需要安装alsa-utils sudo apt-get install alsa-utils # Ubuntu/Debian
设置开机自启动
Windows
- 创建快捷方式到
shell:startup文件夹 - 或使用任务计划程序
Mac
# 创建plist文件 ~/Library/LaunchAgents/com.volume.auto.plist
Linux
# 添加到crontab @reboot /usr/bin/python /path/to/script.py
根据您的具体需求选择合适的脚本，如果只需要基本的定时调节功能,推荐使用PowerShell或Python版本。
