SoundFlower - The Missing OSX Audio App you always needed.

I cannot sing their praises enough.  SoundFlower is a fantastic OSX app, and for the AV/VJ community, it is an absolute necessity.

It allows you to pass audio output. back into the internal audio mix with 64 internal virtual channels.  

Soundflower is a Mac OS X kernel extension that enables audio to be passed between applications. It acts as a virtual audio device, with both inputs and outputs. With it, any audio application can send and receive audio.

Initial support for the development and maintenance of Soundflower was provided by Cycling '74. Stewardship has now been passed to Rogue Amoeba, and we're providing hosting of the latest version.

Soundflower is an open source project. Code for the Soundflower project is now hosted on GitHub.

WARNING: Open Source Screen Capture Software CamStudio has a Virus!

I'm sorry to report that the extremely popular Open Source Screen Recording software CamStudio has been infected with the Artemis!935C478B6850 trojan.  I had recently installed CamStudio in order to produce a tutorial video, and I began to notice a ton of new applications popping up and marked decreases in performance.  Guess its time to dust of those Windows 7 install discs....

A search of wikipedia yields some disturbing results.

I can confirm this is still the case as of today. I downloaded the file straight from, and McAfee quarantined Artemis!935C478B6850. Vegemarmalade (talk) 22:55, 19 March 2014 (UTC)

Although I have been using CamStudio for years now, I recommend you seek out alternatives to this software.  Further exploit information can be found at HerdProject. 

Some people are Using VLC to capture/transcode their desktops, though I've had mixed results.

Mac Users can use a little known feature in Quicktime Player.
