The size has been growing for the past 4 years, that's nothing new. This many years later and now it's a spec of dust on the radar, so yeah, it is growing, before it just didn't come up.
For the longest time, turbo and I were the only audiophiles on here. Then Scott came around, and now there's probably 10 or so of us on here. Great, so 10 or so, who is going to code software for 10 or so people? It's going ot take a while longer before someone can see the reasoning behind investing that amount of time and money into a product like we're looking for.
Regarding the hardware set-up: I'm not just talking about car audio, I'm talking about audio in general. Professional Audio. Currently, no one is going to write universal software for a car audio environment. The place to look is in the professional audio relm. In the professional audio relm, there's no need for this kind of thing.
Show me a piece of crossover software? Have you seen the thread I've started regarding this whole thing? So far, we've found one that looks to be even remotely viable.
Why USB? There's not many people running a full tower in their car. Many people aren't even running cases. If you're not running a PC case, where are you going to secure a PCI card? If you are running one of the tiny cases, many times the use of the PCI card slot is put in a position in which running a bunch of RCAs isn't going to work very well.
What I'm seeing here is someone that is brand new to the CarPC scene. They have an idea about what they want but they haven't done the research yet to see what does or does not exist out there yet.
Do me a favor, if you know of all this software that's out there, why don't you post it?

We could use more people actually working to improve the situation rather than just complaining about it.
