Connecting the Audio Source
While some video capture devices will also capture audio, this method can be unpredictable depnding on the capture device and audio card in your computer. Some audio cards handle audio capture with video capture devices differently. Therefore, it is often best to capture audio directly into the line-in or micophone jack on the audio card of the computer.
Connecting Directly from a Camera
Most audio cards have 1/8 inch mini jacks for the line-in or microphone jack. Most video cameras have a 1/4 inch stereo output. To connect a camera to an audio card in this scenario, you will need a cord or adapter that steps down the size of the cable from 1/4 to 1/8 inch.
In your operating system's audio settings, you will need to set the microphone or line-in as the selected audio source for recording. Once connected, the Streaming Video Console should detect the audio. If the console does not detect the audio, you may have to change your Flash Player settings to select the camera as the audio input source. for more instructions on changing the Flash Player settings, go to adobe.com
Connecting from a Sound Mixing Board
For clear stereo sound, it may be preferred to connect audio from a sound mixing board. To do this, simply run a cord from the mixing board's output to the computer's audio card using a cable or adapter to step down the size of the cord. The audio going into the mixing board may be from a camera, switcher with audio capabilities, microphone system, or any audio device connected to the mixing board. Using a mixing board also allows multiple audio sources such as microphones or background audio.
