A pop filter is a device used in audio recording to reduce or eliminate popping sounds caused by plosive consonants, such as "p" and "b." It typically consists of a mesh screen stretched over a circular frame, which is placed in front of a microphone. By diffusing the airflow from the speaker's mouth, it helps to create a cleaner sound without distortion. Pop filters are commonly used in professional studios and home recording setups. They are essential for vocal recordings, as they enhance sound quality and make the final product more pleasant to listen to. Many musicians and podcasters rely on pop filters to improve their audio clarity.
