Vocal processing refers to the techniques used to enhance or modify a singer's voice in music production. This can include adjusting pitch, adding effects like reverb or delay, and equalizing frequencies to make the vocals sound clearer and more polished. Tools like Auto-Tune and Vocal Harmonizers are commonly used to achieve these effects, helping to create a professional sound. In live performances, vocal processing can also be applied to ensure that the singer's voice stands out in the mix. Sound engineers use mixing consoles and digital audio workstations to manipulate the vocals in real-time, allowing for a dynamic and engaging experience for the audience.
