Hello
FM24 does a simple and amazing thing - the sound in the dressing room is a muffled version of what you hear in the game - and as you start the halves you get the full roar of the crowd.
My ideas is simple - that instead of having this like a light switch between the two - whenever you press dressing room or start x half instead of a light switch approach the EQ filter opens up (or closes down) gradually over a second or two... giving a sense of entering or emerging from the tunnel.
I suspect this will help immersion and also will heighten the tension and goose bumps in big games.
Thanks
Juz
ps happy to mock this up if you need any clarity
