What is the significance of using a pop filter with microphones?

Using a pop filter with microphones is significant primarily because it serves to reduce plosive sounds from speech. Plosive sounds occur when a burst of air is created by consonants like 'P' and 'B', which can produce unwanted noise and distortion in recordings. By placing a pop filter in front of the microphone, these bursts can be softened or diffused, preventing them from causing spikes in the audio levels. This leads to clearer and more professional sounding recordings.

While improving sound quality may seem relevant, it’s specifically the management of plosive sounds that is the core purpose of a pop filter. Similarly, amplifying the speaker's voice and filtering out background noise pertain to different aspects of audio production that do not directly involve the primary function of a pop filter.
