    Software idea: audio enhancer based on passenger...

    Hi guys, I recently rented an Audi A8L (what an amazing car) and tinkered extensively with the MMI and audio system to get ideas...

    One amazing thing is the Bose-whatever-its-called option... basically it allows you to enhance the "sound focus" for Driver, All, Rear Seat... it makes a GOOD difference in sound quality if you are alone in the car and select Driver, it also improves the sound noticeable if you select rear seat, for rear seat passengers but it makes it a bit worse for driver/passenger (basically it isnt BS, it really works and makes a differnece)...

    I guess it works by raising/lowering volumes and strenghts on each individual speaker based on a certain pattern for each "zone"... is this possible with some current winamp plugin or software? Would anyone be interested in taking up this project? it was pretty cool... but prolly not worth itif it isnt easy to implement... i guess it would be a bit hard to "tune" the system for each "zone"....

    I think that what you want it's possible with motherboard that supports 5+1 channel mode.

    in this case you can control the volume of rear, front and central/sub.

    I've recently found this software for via-epia motherboard.

    look my last post

    I don't think it's possible set up predefined configurations (for example single guider, guider with passenger...) to do this, probably it is needed some development on the front ends... but I don't konw if it's possible...


    bye.

    Yeah, sorry if I didnt make it clear... it is surely done with 5.1 or 7.1 or whatever sound is in that amazing car (the amount of speakers is tremendous... like 3 sets behind the rear-seat headrests, a bunch in each door and so on).... I realize that that is how it works (by adjusting volumes independently on each speaker)... the idea is to have a "preset" level for each option and a GUI to bring em up from your frontned.... (preferably a RR plugin or somerthing)

    I bet it doesnt compare to what is on the A8 though! I was amazed at the sound difference in each setting.... The merc has this too but doesnt come to the feet of the audi...

    what a nice car... I'm still in awe.... the air suspension (just like the Rangie) is amazing, the engine was plenty of power (although I can only imagine how fun the S8 would be), the keyless entry, starting engine, etc (just touch the door with key in pocket and it unlocks car).... man what a cool car...

    I thought that the MMI interface would defo have benefited from a touchscreen rather than the knob.... at times I found myself poking at the screen insticntively

    Are you sure the system wasn't based on time correction? Since the driver, for example, is much closer to the front left speaker than the rear right speaker, a time correction system will play sounds through the front left speaker x number of milliseconds (x depends of the actual distance) after the rear right speaker plays the same sound, so that the sound from each speaker reaches the driver's ears at the same time (right rear speaker sound has to travel further, so it takes longer). The other speakers are similarly delayed so that all sounds played by each speaker reach the driver's ears at the same time. It seems to me like that might be more likely/make a larger difference than adjusting speaker volumes.

    I'm sure you could make a script for the kXProject drivers to do what you want.
    kXProject is for more cretive PCI cards. They allow you to do delays, which is basically what the audi system does.

    check out the eclipse 8 series radios. Theyve had that feature built in for at least three years now.

    and those settings are for when you ARENT in "pro mode"
