Every sound I identified as iconic (as a fan) is remastered, said Couthier. A combination of EQ, redesign/ re-synthesis, adding new layers to fill gaps in the spectrum, and increasing impact and dynamic range. Almost all other sounds have been totally redesigned with modern tools. Weve added real-time parameters in code (such as altitude, acceleration, doppler) to better represent gameplay with audio.
With PS4 developers encouraged to achieve an average loudness of -24 LUFS, Couthier knew he would have way more headroom compared with previous titles released during the loudness war: The original games mixes were (as youd expect) very flat, but the new standard allows much more dynamics.
