Boundary layer microphones with XLR and Standard Jack connections have been around for years. But now there’s a number of USB boundary microphones available adding the convenience of a USB connection, allowing you to plug directly into your laptop computer for high quality, mobile sound recording.
Because boundary microphones generally have a 360 degree omni-directional / hemispherical sound pickup pattern, they’re a particularly good microphone choice when you want to record everything around you, such as meetings, round-table discussions, classroom lectures and conferences. With a little creative placement, they can also produce good results recording instruments, vocals or band recordings.
If you’re looking for a powerful and effective USB microphone, but are on a tight budget, a boundary microphone could be a great way to go.
We’ve rounded up a few USB boundary microphones ideas to take a look at:
