Having high-quality audio in your webinar video production is even more important than having a perfectly crisp picture. People need to hear the dialogue and information to understand what’s going on.
Quality Audio Checklist:
1. Plug headphones into the camera to listen to the audio feed while you’re recording. That way you will be able to hear more detail.
2. Always do a sound check before you officially begin recording. Check audio levels and sound quality.
3. Remove all background noises, if possible. Check for buzzing from items like refrigerators or ventilation systems.
4. Avoid filming in open rooms with tile or other building materials that could create echoes.
5. Make sure you stop or pause your recording if you’re interrupted by loud noises like sirens or construction.
Use Lavalier Mics to Individually Mic Each Person:
If you are recording an interview, you may want to individually mic each person to make sure the sound comes in loud and clear. For this video, use a lavalier mic, also known as a “lav” or “lapel mic.” Lav mics clip onto a person’s collar or shirt a few inches from a person’s mouth.
1. Check what kind of audio input your camera uses. (Most likely, it will be XLR or 1/8 inch input.)
2. If you are putting a mic on each person, use a soundboard to collect all of your audio feeds. Connect the soundboard to the camera.
3. If you don’t want to use a soundboard when using two mics, use a splitter to enter two feeds into one jack. However, this may decrease the audio quality or cause a slight buzzing sound.
4. For wireless mics, clip the transmitter onto the person being recorded. Make sure they turn the transmitter on!
Use a Boom Mic to Record a Scene:
If you are recording a video using a hand-held camera, you may want to use a boom mic. A boom mic, or shotgun mic, is a directional microphone that connects to the camera. For most boom mics, you will need a camera with an XLR input.
