Background Music

macOS audio utility

• Automatically pauses your music player when other audio starts playing and unpauses it afterwards
• Per-application volume, boost quiet apps
• Record system audio
• No restart required to install
• Runs entirely in userspace

Version 0.1.0, first release. Probably very buggy. Not very polished or well tested.

Requires OS X 10.10+. Might work on 10.9, but I haven’t tried it. Currently unable to build in Xcode 6.

安装：打开终端，粘贴以下命令，回车；

(set -eo pipefail; URL=‘https://github.com/kyleneideck/BackgroundMusic/archive/master.tar.gz‘; \ cd $(mktemp -d); echo Downloading $URL to $(pwd); curl -qfL# $URL | gzcat – | tar x && \ /bin/bash BackgroundMusic-master/build_and_install.sh -w && rm -rf BackgroundMusic-master)

软件只有130kb。

进度条到100%以后就完成了，不用重启，即刻生效。

但是安装时会出现几秒钟的音频暂时中断，因为要安装驱动。

MacOS Sierra 10.12.3 测试完美。
