Str8UpJack: Thank you! We definitely aim to provide a quality product that's useful and reliable. I'm glad you liked it!

Thomas Byskov Dalgaard: Compared to our other software, which is aimed at a mainstream audience, Loopback is a fairly targeted product. Given the power it provides, and the amount of time and hassle it can save, we're confident it will be worth the price to a large enough audience.

Tom Pollock: Audio Hijack and Loopback are somewhat similar, in that they both capture audio from applications and devices, but they serve different purposes. With Audio Hijack, you can make a recording with the audio captured from input devices and apps, saving it to a file. With Loopback, you can grab audio from those same sources, input devices and apps, but then pass it to another application.

Loopback passes audio between apps by creating virtual audio devices. These devices acts ust like a physical device you plug in to your Mac. With them, you can pass the audio from devices and apps you select, back to other applications. So if you’ve got audio from your mic and iTunes, and you want to get both of them into Skype, you just create a device in Loopback that consists of your mic + iTunes. If you’ve got audio in FaceTime that you want to pass right to GarageBand, you can, and so on.

As far as Aggregate Devices in Mac OS X go, they let you combine sources. Loopback does this as well, but it also does a lot more. To begin, you can combine not just audio hardware, but software application sources as well. As well, the custom channel mapping provides much more flexibility for your virtual devices. You can even monitor the device's output through another device. None of that is possible with the OS's aggregate devices.

The other major win is Loopback's pass-thru devices. If you create a device in Loopback and do no further configuration, you can use it to pass audio directly from one app to another. Just select that pass-thru device as the output for apps you want to send audio from, and the input in the app you want to receive the audio.

Dr Tone: Do you mean "hog mode"? I can't say we've tested with that (as it's not a frequently used feature). Everything happens on the CoreAudio side, so I would assume Loopback will work with it just fine. Grab the trial and test it out!
