Fallout 4 High Quality Audio is a mod that adds the voice over audio files from the PS4 version of Fallout 4, Automatron, Far Harbor, Vault-Tec Workshop, and Nuka World. While the PS4 version of Fallout 4 uses the same bit rate as the PC version, the quality of the lossy encoder that PS4 uses is better and the PS4 DLCs use a higher bit rate.
