This will mean that Audio Hijack takes the audio input, blocks background noise, and outputs it to our virtual device. Click on the box and select the Loopback Device that you created a moment ago from the dropdown list. Add an Output Device after the AUDynamics Processor. To do this, we'll use our virtual device from Loopback. I didn't want to save the audio to an mp3 and then import the mp3 into Camtasia. I create my courses for Thinkster in Camtasia, so what I really wanted was to have this manipulated audio fed right in to that application. But before we do that, I want to change the output of the processed audio. With that effect in there, we are ready to manipulate the audio. Open the "Audio Unit Effects" dropdown and find "AUDynamics Processor" from the list and drag it until it sits between the input and the mp3 output. You can get that from the menu on the right hand side of the session configuration window. The one we want to use is called "AUDynamics Processor".
We now need to add an effect to the sound. Now just this alone will not get rid of background noise for you when recording. It takes the sound from an input device and outputs it to an mp3 recording. This gives you the following starting point for your session: You can choose a template or create your own from scratch. This will give you a screen of options for the session you'll be creating. Start by opening up the application and clicking on "New Session". So this seemed like the perfect application for my needs, and I dug in to get it set up. You can even output it to a recorded file if you'd like. You can choose different inputs and sources, and select the outputs as well for the audio. I looked around and found a few options, but the one that seemed most up to date and current was Audio Hijack by Rogue Amoeba.Įssentially, Audio Hijack does just that: it hijacks the audio on your computer and gives you the option to manipulate it.
So I kept on searching, and found some suggestions of using a noise gate program. I found a couple tutorials on noise removal, but they didn't really seem to remove that much noise. It's a great tool, but it wasn't very user friendly. So I started looking for ways to get rid of the hum, and was led to Audacity. The only problem was a small hum, and it wasn't terrible but it did bug me (partly because I'm a perfectionist). Most of the time I'd get it close to right, but not always. So it was really tough to get everything just right. If the external hard drive started running, that was definitely getting picked up. If someone walked across the floor upstairs, that would probably get picked up. If a car drove by outside, that might get picked up. I've been recording courses for Thinkster.io for about a year now, and each time I'd record I'd have to make sure my office was dead silent. Simple, huh? We'll use that in a minute after configuring Audio Hijack. The screen will look like this after you do that:Īnd that's it! You've created your virtual device. At the top of the screen you can give it a name so that it's easy to identify later on. Open Loopback and create a new virtual device. Let's create the virtual device we'll use for Camtasia. In our case, we're just going to create a virtual device that can be used as an output device from Audio Hijack.
Loopback vs audio hijack software#
This allows you to take audio from application A and pass it to audio processing software B.
It allows you to capture audio in one (or more) applications and route it to a new virtual input device.
Loopback by Rogue Amoeba is a great application to manage audio on your computer. I am by no means an expert, and will continue to play with these programs and settings, but what I have set up now seems to be working great. By the end of this post, you should be able to have everything set up. Using Audio Hijack and Loopback from Rogue Amoeba will help improve the quality of your sound output. The great thing is you don't need to spend a fortune on equipment to get this quality. Your listeners will hear nice crisp audio, and there won't be any fans or anything in the background. A proper setup of the audio on your computer will make for great recording quality.
