Loopback是一款由Rogue Amoeba开发的Mac音频路由工具，它允许用户在Mac上非常方便地调整和管理音频输入和输出，是一款非常实用的应用程序。

Loopback的主要功能是对Mac系统的音频进行路由和切换，它可以将来自任何应用程序或输入设备的音频混合并且输出到任何输出设备，同时支持实时的音频处理。用户可以通过Loopback将多个音频源组合在一起进行混音，或者把它们分离开来进行处理和录制。

Loopback的最大特点是可视化操作，其主界面非常简洁、易于操作，用户只需要拖动和连接音频节点，就可以完成音频的路由和切换。用户还可以为不同的音频设备和应用程序设置不同的标签，这样可以更方便地识别和管理音频。

此外，Loopback还提供了许多高级功能，例如允许用户创建“虚拟设备”，用于将音频从一个应用程序传输到另一个应用程序，或将多个音频设备混合在一起并将音频输出到任何输出设备。用户还可以为每个虚拟设备设置独立的音频处理选项，以确保音频质量和效果的最佳表现。

Loopback支持多种输入和输出设备，包括内置麦克风、系统音频输出和外部音频接口。此外，它还支持多种音频格式和编码，包括MP3、AAC、WAV等。用户可以根据自己的需要选择最适合自己的音频格式和编码。

Loopback makes it easy to pass audio between applications on your Mac. Create virtual audio devices to take the sound from applications and audio input devices, then send it to audio processing applications. Loopback gives you the power of a high-end studio mixing board, right inside your computer!

- Play Audio to All Your Podcast Guests - Combine your mic with audio sources like iTunes or QuickTime Player, then select your Loopback device as your source in Skype. Presto! Your guests all hear both your voice and your audio add-ons.

- Record Gameplay Videos - Making gameplay videos with great audio can often be very difficult. If you're using a device like Elgato's Game Capture hardware and you want to record both your microphone and the game's audio at once, Loopback can assist!

- Combine Hardware Devices - Apps like GarageBand, Logic, and Ableton Live only record from a single audio device at once. Thankfully, they offer recording from many channels. With Loopback, you can combine multiple input devices into one virtual device for easy recording.

- Create Top-Notch Screencasts - Screen recorders, including QuickTime Player, allow you to include your mic's audio. Some allow recording of system audio instead, but neither option is ideal. Create a virtual device that grabs just the mic and the app’s audio to get exactly the audio you want.

- Route Audio For Broadcasts - Set a simple (pass-thru) device as the output at the end of an Audio Hijack chain, and then as the input source in Nicecast. Now listeners can tune in to a live stream of your podcast as you record it!
