Alright, welcome back to VO Tips for the Non-VO Pro!
Last time we discussed condenser versus dynamic mics, and I thought it wise to continue the next logical topic: USB versus XLR. Aaaand what am I talking about?
What they are:
USB mics plug directly into your computer, tablet, etc. through a USB port. XLR mics require an XLR cable and something called an audio interface, which I’ll cover in a separate video. But essentially both of these do the exact same thing. They convert soundwaves into digital signals (1s and 0s) which your computer can then read and display as a 2D waveform. USB mics, however, are generally lower quality and more limited in their use.
Why USB mics are limited:
For example, last week we talked about condenser versus dynamic mics. Say I normally use a condenser mic like this but needed more external isolation and wanted to use a dynamic mic. I could simply swap them out easy-peasy. You’d have to adjust many settings on your computer if you wanted to swap out a USB mic because you swapped out the audio interface as well. Also any preamps and added signal processing tools, which I’ll discuss later, but essentially things to make the mic and therefore my voice sound much nicer, cleaner, louder—better—cannot be added to a USB mic.
Some great USB options:
There are some very powerful plugins that can do a lot to enhance mic signals, and USB mics ARE getting increasingly better in their quality. The Rode NT-USB is my personal favorite. Many voice actors unashamedly take pride in their Apogee MiC (M I C) USB mics, and then there are others like the Audio Technica 2020. The Blue Yeti is the ubiquitous mic for anyone looking to start their podcast and in general produces an OK sound. It’s likely good enough for you to start out. However, if the goal is to make better sounding audio, you’ll eventually want to upgrade to a dedicated audio interface and XLR mic.
And again, if you have a poor recording space—no sound isolation or acoustic treatment—a dynamic mic would be your best bet.
