    Newbie mac audio question

    Is there anything that will let the Mac do time alignment and proper EQing? To me that would be a huge advantage for a carputer and it seems that I would end up spending some money to get that functionality another way otherwise...

    Not sure. Probably my audio ignorance, but what do you mean my time alignment?

    I really have no idea what yer talking about...

    time alignment? WTF is that.... are you talking about audio/video sync?

    EQing? You mean having access to an equilizer? Built into iTunes, that not good enough for you? There are no front ends yet, so asking someone to put an EQ into it, wouldnt really help yet.

    EDIT: i googled time alignment and got it, you mean the distance of speakers. You want something that will thru digital processing give you a better soundscape by dialing in the distance of the speakers to your ears.

    if you use a third party audio thing, like a PCI card or firwire breakoutbox, they usually come with a software interface for setting up your system and setting the distance/height etc of each individual speaker.

    again, this is really techincal and not implemented (or planned to be) in any of the work in progress OSX front ends...

    Explanation

    Time alignment or time correction is the ability to delay specific channels so that you can compensate for speakers being at different distances. So the passenger side tweeter which might be twice the distance from the driver's side one might emit sound a few milliseconds earlier to adjust for the difference in distance.

    Real EQ versus the BS that iTunes has would sample sound from your car, determine which frequencies are being over and underemphasized by the layout of the speakers and the car and then compensate properly.

    Alpine, Clarion, JVC, Pioneer and others all make high end units that can automatically set up and adjust the sound to compensate for these problems for more accurate sound. There apparently is PC software available to do this, but I have not been able to find anything on the mac side.

    So you want to run something constantly in the background of your OSX front end that is constantly doing this for your music? Or you want something to be able to set it and forget it forever...

    Real EQ vs BS... i dont understand, a software EQ of any type is still an EQ.

    You are really talking about stuff that really, IMO, has a place in Home Theatre design. While it is cool to try this in the carputer situation, you really wont find that your sound experience has gotten any better. How could it... your are in an airtight volume that is smaller than most closets....and what about when the windows are down, what about just the back left window halfway down, that ruins your soundscape....

    Im sure there is a piece of mac software that will give you control over your audio not just thru iTunes. But again, the mac audio out is NOT multi channel. Unless we are talking about the optical out on the G5s...

    Anyway, whatever you use to get multi channel audio out of your Mac will come with its own software to do what you are looking for. I think.

    It really need only be set once with profiles for when there are two passengers. I think it has more of a role in car audio where you have no real control over speaker placement or room dynamics. There is software available to do so on the PC side, but since I would never use a PC if I didn't have to, I am merely trying to find out if there is anything on the Mac side.

    Obviously car audio people generally agree as it is built in on many head units. The JVC SHX850 has a microphone you put in your car where it will automatically set the EQ and time settings.

    Basically I am trying to maximize the sound quality that my future car computer will have. Better to evaluate in the planning stages my option.

    Gotcha. Well, it doesn't come built in to the Mac, or with the Mac software. It would be an add-on if it exists.

    if you are that serious about this stuff then perhaps its best you look at recievers like the alpine one red is using

    Man u didnt even read my post.

    If you have 4 speakers in your car thats cool.

    your mac was built to see 2 speakers, with a line out.

    So how the hell are you getting the rest of your channels? Ill tell you: you will buy a 3rd party item to make your mac output 4 channels or more. AND WITH that piece of equipment will come software to do yer speaker distance stuff.

    You say there is a PC program to do this, but in the end ummm how can that work when a computer only comes with line out, and maybe sub out. Your program is letting you set distance and stuff for speakers that arent even connected to the computer.

    Buy something to give you more outs for speakrs and it will have what you are looking for.

    DONT keep your head unit if you dont have to.
