Hi Tom,
Sorry for the late reply i was away on holiday.
I've tried reproducing the issue again after patch 1.03 and things have improved a bit, but not to the whole extent that i would expect from a game with high quality audio.
The exact system that i'm using is a pair of Genelec 8330s studio monitors connected to a Genelec 7350 studio subwoofer. This calibrated combo reproduces anything between 19hz - 20khz with great precision as they are made for music production.
The Genelecs are connected to the PS4 via optical out. The PS4 is set to output 2.0 PCM audio via optical out.
In NFS, all audio sliders are set to 100%. I've tried setting sound to "Home Cinema" and "Headphone". "Headphones" sound better with a bit more bass.
For the purpose of reproducing this issue, one would just need a pair of 2.1 speakers (2 speakers and subwoofer) connected via optical out to the PS4.
Audio must be set to 2.0 PCM not 5.1.
If you than mute the speakers and let only the subwoofer play, one can easily monitor the low frequency content of the NFS sound track and in game effects.
If the subwoofer is not doing much, than there is little low frequency content on the sountrack and the game will not sound so good.
The issue that i'm reporting is that there is little low frequency content in the game, certainly less that i'm getting while listening to bass heavy music, as the NFS sound track should be.
For example, my Genelec have digital volume.
At -40db, which is very loud, while listening to normal music outside NFS, the subwoofer ouputs a great amount of bass. In NFS at -40db i can barely hear anything from the subwoofer.
At -30db, which is extremly loud, while listening to normal music outside NFS, the subwoofer feels like it's tearing down to room. In NFS at -30db, the subwoofer finally starts moving a bit.
Does it make sense what i'm saying?
Does your team have any way to monitor the NFS sound track using a subwoofer?
Later edit: Just had the change to do a comparisson with StarWars BattleFront that is also a title with a lot of action and a good sound track.
Compared with NFS, in SWBF each action is nicely emphanised with low frequency effects so you can feel each shot and explosion. At -40db in SWBF the subwoofer is very active.
It would be useful to look into this a bit, otherwise NFS will sound pretty dull with higher end 2.x systems when connected straight to the PS4.
