Omnidirectional microphones

The omnidirectional microphone picks up sound evenly from all directions. You can think of it as a point in the middle of the sphere that hears everything that happens on the surface and inside with the same sensitivity, whether the sound is coming from the front, back or side. Its directional characteristic, which is a graphical representation of the microphone's sensitivity to sound from different angles, is shaped like a perfect circle. This characteristic makes it suitable for recording the overall atmosphere of a space, such as the sound in a room, a concert hall or natural scenery. It is equally suitable for situations where multiple sound sources need to be captured at once, such as a discussion between several people at a table or a choir singing. On the other hand, it is not an ideal choice in noisy environments, as it picks up all surrounding distracting sounds along with the main sound. The advantage of omnidirectional microphones is that they do not suffer from the so-called "proximity effect". This means that they do not accentuate bass frequencies when the sound source is brought closer to the microphone, so the sound maintains a consistent character regardless of distance.
