核心用途场景

• 向所有播客嘉宾播放音频：将你的麦克风声音与 iTunes、QuickTime Player（快速时间播放器）等音频源合并，随后在 Skype（ Skype 聊天软件）中选择 Loopback 虚拟设备作为音频源。就是这么简单！所有嘉宾都能同时听到你的声音与你添加的额外音频。
• 录制游戏视频：录制音频质量出色的游戏视频往往难度较高。如果你使用的是 Elgato（埃尔加托）游戏采集卡等设备，且希望同时录制麦克风声音与游戏音频，Loopback 就能为你提供帮助！
• 合并硬件设备：GarageBand（库乐队）、Logic（逻辑音频工作站）、Ableton Live（阿布顿现场工作站）等音乐制作软件，通常一次只能从单个音频设备获取录音信号，但好在它们支持多通道录音。通过 Loopback，你可将多个输入设备合并为一个虚拟设备，轻松实现多设备同时录音。
• 制作顶级屏幕录制音频：包括 QuickTime Player 在内的屏幕录制工具，虽支持收录麦克风声音，但部分工具仅支持录制系统音频，两种方案均非理想选择。使用 Loopback 创建虚拟设备，仅抓取麦克风与目标应用程序的音频，即可精准获得你需要的声音。
• 为广播节目路由音频：在 Audio Hijack（音频劫持工具）的处理链条末尾，将一个简单的 “直通式（pass-thru）设备” 设为输出端，再将其设为 Nicecast（尼斯广播软件）的输入端。这样一来，你录制播客的同时，听众就能实时收听你的播客直播流！

支持的操作系统

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!
