Tony Maserati employs parallel compression to enhance the vocal's intelligibility.
He uses slow attack and fast release settings with a 12:1 ratio, aiming for 4-7dB of gain reduction.
Additionally, he applies De-essing to prevent the parallel from becoming too aggressive, and cuts some lower mids and lows for clarity.
He also automates the level of the parallel path during different sections to maintain vocal clarity throughout the song.
