If you want to record your Screen with Internal Audio on your Mac you should defiantly look at our free option for doing that.
CASTER free version lets you capture your desktop audio and stream it to any streaming software, and at the same time monitor the audio in your headphones without any additional configuration – and it’s all for free.
We added another freebie to the CASTER and this is our Soundboard track. it lets you play audio (sound effects, into, alerts, etc) into your stream alongside your desktop audio.
another cool free feature is that you can choose to stream only specific application audio running on your Mac and not the entire desktop audio. you will just need to choose this application in the desktop audio track.
On top of this, you have an option to record all tracks from within CASTER – a free feature as well.
And you can add some AU plug-ins to your tracks for cool processing.
