My thanks to Rogue Amoeba for sponsoring Six Colors this week to promote Loopback.
Loopback is an audio utility that lets you route Mac audio where you want it to go. Believe it or not, if you want to route sound from one app (say, Garageband or QuickTime Player) to another app (say, Skype), you can’t. You can input audio from hardware devices, but not from software. Loopback changes this, so you can send audio to and from another apps (as well as hardware), mixing and matching as needed. It’s the missing link in building Mac audio workflows entirely in software that would previously have required routing audio out of the Mac into a mixer and then back into the Mac.
I use Loopback in conjunction with Audio Hijack to record podcast audio and stream it live using another Rogue Amoeba app, Nicecast. (Similarly, if I want to play audio from my Mac and have it heard by the people on a Skype call, Loopback is what I use.)
If you need to route audio around your Mac from app to app, check out Loopback. It’s free to try, and you can save $20 when you purchase by using coupon code SIXCOLORS1609. Act fast, because this deal only lasts until the end of the month!
