A VU (volume unit) meter is a type of analog meter that is used to measure the average level of audio signals. In a recording studio, a VU meter can be used to ensure that audio recordings are at the proper level, and that they don't peak or fall below a certain threshold. This can help to prevent distortion and ensure that the audio is clear and of high quality. Additionally, VU meters can be used to ensure that the audio levels are consistent across different tracks and recordings, which can help to make the final mix sound more cohesive.
