Separate Audio Channels

I record all the microphones in a deposition on separate channels, while simultaneously sending a stereo mix to the camera as a backup. This allows me to clean up indistinguishable audio after the fact, if needed. All too often, when the witness is giving an answer, another person with a mic might cough, rub the microphone, ruffle their clothing, or a cell phone may go off. A traditional deposition videographer runs the microphones into a mixer that mixes, or blends, all of the microphones into just two audio channels (or sometimes even just one!). This makes cleaning up the audio later impossible: the cough will be on the same audio track as the witness’s answer. Listen below for an example of “dirty” audio.

 

Granted, this excerpt will likely never be used in court because it’s the moments just before a break, but from an audio perspective, it illustrates how much can happen. Now listen below to what I’m able to do simply because I record the microphones on all separate tracks.
