## プロジェクトの歴史と使われ方
SwitchAudioSource is a macOS command-line utility for switching the system audio source without opening the graphical sound settings. Its appeal is narrow but durable: shell users, automation users, and hotkey-tool users can script audio input, output, system device, mute, and cycling behavior.
### プロジェクトの歴史
The upstream README describes a command-line-only utility for Mac OS X, tested across OS X 10.7 through macOS 11.2. The license and README credit Devon Weller beginning in 2008 and Christian Zuckschwerdt for migrating the project to GitHub and adding the next-device option.
### 採用の歴史
The README explicitly documents Homebrew installation, and the input package facts show the same utility distributed through Homebrew, MacPorts, and Nix. That spread is typical for small macOS-native command-line tools that remain useful because they wrap a missing shell affordance.
### 使われ方
Users run SwitchAudioSource to list devices, print the current device, set a device by name, id, or uid, choose input/output/system device type, select human/CLI/JSON output, or toggle mute status for input or output devices. The README gives microphone muting as a hotkey-oriented use case.
### パッケージ好きにとっての重要性
Package nerds care because this is exactly the kind of tiny Mac utility package managers preserve: a single-purpose CLI that exposes system behavior to scripts, dotfiles, launchers, and keyboard automation.
### タイムライン
- 2008: Copyright attribution begins for Devon Weller in the upstream license/README.
- 2011: Copyright attribution begins for Christian Zuckschwerdt in the upstream README.
- Homebrew era: The README documents brew install switchaudio-osx.
- macOS 11.2 era: The README states the utility was tested through OS 11.2.
### Related projects
- The project is related to macOS automation, hotkey managers, and dotfile scripts that need to select audio devices without GUI interaction.
