1/3 Octave Software EQ

an all in one solution would be a double din head unit that is a pc designed especially for cars. It's sound card would be equivalent to a H701 and it would have rca outs that go to the amps. The sound card would be like an equalizer and there would be a remote to control those settings and to tune the sub level. There would be a slot load dvd-rw drive and four usb ports on the front...this would be an all in one solution.

heh - so who wants to help design this bad boy??

Not It!

doesn't sound too hard. Get an P3 1ghz sbc, an MP3+, a USB hub, a griffen power mate (to control the levels on everything and cycle through) and LCD form a nite-max (to be the interface), and a programmer and you got yourself a maybe a 1-1.5 din solution with a software based eq.

with crappy pre-out voltage and noise

Genesis - I don't think you've gotten the whole point to this thread....lol

All of the ideas that i presented have been done already. Many people are currently using double din computers, but the part that's missing is the H701 audio equivalence factor. The computer needs to be designed as a head unit with a remote that has sound menu options that pop up over windows (much as a monitor's options menu would pop up over whatever is in the background). The RCA's should have at least 4V with an optional optical out. The carputer should also have it's power supply integrated much as a standard headunit so that standardized connections can be used when replacing a stock headunit. The computer should be developed to ensure instantaneous boot times and the front end should be linked to the sound card controllability.

Those are my requirements...now develop!....lol

I noticed most of the software EQ options are plug-ins...usually compliant with a standard called VST (Virtual Studio Technology). Sorry if this is common knowledge...it wasn't for me so I did a little research. Here are a few links of interest:

Wikipedia page on VST - explains a lot
Audacity - an open source VST host capable of accepting a plug-in
Muse Research's Receptor - a piece of hardware that accepts VST plug-ins. Thought this was interesting because it shows that people are trying to do the exact opposite of us...process the sound off the computer. Might be controllable from the PC and would take on all the processing load.
