What techniques were used to achieve a more believable broadcast sound.

Developer and publisher Codemasters has put out the final developer diary in its four-part series for upcoming racing game F1 2018.

Aside from covering how the game looks in terms of car models, character renders, visual effects, cinematic pieces, and animations, the studio’s senior audio designer Brad Porter also spoke about the extensive work that went into making the game sound believable and authentic.

“Every year we update our engine bundle, we make them as realistic as possible,” explained Porter. “We try and make them as close to broadcast as possible, which is what a lot of fans ask for. We’ve been over to tracks such as Abu Dhabi, Barcelona and Paul Ricard over the last year, working directly with F1 teams, going into garages with them on test sessions, mic’ing up the cars on board with our new radio gear, and then we’re standing at the side of the track for externals. We’re also in the garages recording ambisonics, we’re out in the paddock, [and] we’re out in the pit lane.

“We’ve overhauled the distance tones this year, we’re no longer just filtering out the bundles anymore – we’re actually getting authentic sounds of F1 cars at distance and blending between the on-board and the external shots and it’s created a far more believable broadcast sound.

“We’ve overhauled the reverb system this year, so we’re now using positional reverb – it actually sits in the world where it’s supposed to be now instead of being 2D. We’ve also overhauled the reflection system now so on a subconscious level it gives the player an indication of how close to barriers or other objects they are.

“Dolby music is now mixed and mastered in surround. We wanted the music to feed into the expensive nature and tech of the world so you’ll notice one organic soundtrack throughout the front end.

“The submenus all follow one coherent theme but there’s slight differences between each menu, so we’re trying to feed in with things… like time trial you’ll hear little bits of ticking in the music. When you go into the options menu we drop everything down and just have a sort of piano so you can concentrate on moving your settings around.

“From an audio point of view, the game is now sounding far more believable and far more authentic.”

F1 2018 will be released on 24th August for PlayStation 4, Windows, Xbox One, Android, and iOS.
