Recording from a mixer to a computer is easier than you might think.
Recording directly from a mixer to a computer is an easy way to record band sessions and gigs, DJ mixes, presentations and any other live audio. The process is simplified by the fact that each of the tracks is already mixed to an appropriate level before it reaches the computer, so it is only necessary to capture the master mix. With only a bit of effort, you can capture high-quality mixes for post-processing and distribution.
Instructions
1. Connect one of the stereo outputs from the mixer to your sound card. The type of cables you need will depend on the connections available on the mixer and sound card. The mixer will most likely have dedicated recording outputs with either RCA or 1/4-inch jacks, but if not, the headphone jack can be used in a pinch. Sound cards, on the other hand, are more varied and can have any number different types of inputs. Generally, the worst option is to use the built-in line input, usually a stereo 1/8-inch jack, because it can get noise from the computer. It is still an option, however, if there are no XLR or 1/4-inch inputs available on the sound card.
2. Start the recording software on your computer. The software can be as basic or advanced as you like, as long as it meets your needs. Some of the most popular professional recording software include Pro Tools, Logic, Sonar and Cubase, but these are each relatively expensive. A few other options include Reaper, which is not technically free but the trial has no limitations, and Audacity, which is both free and open-source.
3. Configure the audio from within the recording software to record one stereo track or two mono tracks, depending on how you routed the audio into the sound card. For example, if you plugged the output of the mixer into the sound card's line input, simply set the software to record the line input. If you plugged the output of the mixer into two mono inputs, set the software to record those two inputs.
4. Test the levels by playing music through the mixer at whatever volume you expect to be recording at. Check the levels in the recording software to make sure there is no clipping or distortion. If there is, try turning down the levels of your sound card if it has external controls, or else turn down levels from within the recording software. Once the sound is no longer clipping or distorting, try not to touch any controls until it is time to record. Record a few test tracks just to be certain that everything is working properly.
5. Begin recording when you are ready. Keep in mind that if the sound is louder than you expected and the recording begins to clip, it is better to turn down the levels and manually adjust the volume later on than to let it continue to clip.
