Built-in Analog Audio
You can capture and output audio using the built-in audio ports on your computer. The
built-in audio interface on your computer usually uses a stereo miniplug connector. If
necessary, you can buy an adapter to connect the miniplug connector to two stereo RCA
or 1/4" tip-ring-sleeve (TRS) connectors, which can then be connected to your video or
audio device.

For basic mixing, you can connect the built-in audio output on your computer to a pair
of external speakers. This gives you two output channels, which can be configured for
dual mono or stereo playback.
Built-in S/PDIF Digital Audio
Some computers have built-in S/PDIF optical digital ports (sometimes called TOSLINK)
that you can connect to some CD players, DAT recorders, and other digital audio devices.

DV FireWire
If your post-production project uses a DV codec, you can output audio via the FireWire
port on your computer. This allows you to use a DV deck, DV camcorder, or DVtoanalog
converter as an audio interface. In this case, you connect your FireWire cable to your DV
device and then connect the audio outputs of the DV device to external speakers or a
television monitor.
