* Differences between Omni-directional and Uni-directional microphone
Omnidirectional devices broadcast or receive their signals from all directions. Someone who records sound effects and wants a general reading of a surrounding environment (like timber creaking, brooks babbling, and crickets chirping in a forest, for example) would find an omnidirectional microphone useful. Cell phone antennas will (in theory, anyway — varying in reliability depending on carrier and coverage) pick up signals from everywhere around the device.
Unidirectional devices, on the other hand, are more focused on picking up or transmitting their signals in one direction. This is especially helpful if you’re in an area saturated with ambient signals that you want to avoid. Perhaps you’re interviewing a PR representative from a promising startup in a crowded convention hall for a YouTube video. Having a microphone that will give you and your subject undivided attention while ignoring the surrounding hubbub and chatter is a valuable way of controlling the situation.
