Some of you may be wondering why we discussed the video hardware first if audio is the most important part of video. Whereas video is a little more muddled in the connections that are available in the consumer realm, and are often used in churches, audio is a more stable infrastructure at this moment. It is not difficult to bring good audio into a video system.
If you are keeping it simple, using just your phone to record the message, a simple lapel will do wonders for you. Shure makes some of the best mics around, and their MOTIV MVL works with most smartphones, and is the one I use for on the go recording. The Rode smartLav+ is also an excellent choice. Both of those feature a TRRS connector, native to smartphones. A generic TRS connector may still work with your phone, though you’ll likely need an adapter. There are several options for iPhone which use a lightning connector, but they won’t work with any traditional audio equipment. Apogee and Audio-Technica make good options there. If you need to bring in a signal from an audio mixer, mic, or instrument, an interface like the Tascam iXz will be needed. A number of computer USB interfaces could work as well with a lightning adapter.
Video Mixer Audio
Using a traditional audio desk you should have 1/4″ and XLR output options, either of which can be run directly to a video switcher or encoder. If your equipment is structured in such a way that the audio feed needs to run into the camera, that will also work, though some cameras may require an adapter to bring a 1/4″ plug down to 1/8″. In all scenarios, make sure settings are correct. Input signals often have a ‘line’ and ‘mic’ setting. Line will be used for direct connection from sources such as an audio mixer. The mic setting will be used when your source is an instrument or a mic. Some wireless receivers have the option to output as either. Unintended audio problems can occur if a setting is wrong somewhere, like a hiss.
Similar to your phone, a USB interface can be used to bring in audio from mics, instruments, and audio desks into your computer. I am partial to the Focusrite lineup, and have used the Scarlett 2i2 for years. Motu, Solid State Logic, and PreSonus also make excellent options. Options range from one input to eight, and more could be added with multiple interfaces if you need. Belkin used to make a USB C to B cable that I use extensively between my MacBook and old peripherals, if you can find one I highly recommend it.
Audio for video is not complex, you just want to use a good mic and remove background noise. Internal mics on your phone or computer will leave a hollow sound and pick up so many ambient noises that you don’t want. A proper lapel or handheld will give a clean and reliable sound. When avoiding background sounds you’ll want to watch for things like fans, electronic notifications, vents, and noise from nearby rooms like bathrooms and kitchens.
