Hardwire FM is a mod for the Cyberpunk 2077 game that adds a lot of new music and sound effects, as well as improvements to the gameplay and user interface. It is designed to allow players to hear the music they want to listen to in-game while still allowing them to hear other things happening around them.

This is done by fading the audio signal from the game's source so that the player can hear it, but it is also possible to listen to it in the background or even with the speaker turned down. The audio can also be cut off completely, which is ideal for players who only want to hear their own music.
