    Possible To Pull Audio From iPhones Dock Connector?

    All I want to find out is if it is possible to pull the audio from the iPhone's dock connector thru USB into a Windows computer. Just like the iPhone docks do, except I would be using my Carputer ofcourse.

    I know there are iPod interfaces for certain Frontends, but I have been loyal and true to Frodoplayer, it just seems to work for me. And as far as I know, there is no way to interface an iPhone with it, so this would be the next best solution to listen to my iPhone's music in my car.

    Many many thanks in advance for any input. I really appreciate it.

    Two options:
    1) you can get the analog audio stream from the connector (or the headphone jack since its the same thing) and it would have to be connected directly to an amp or an audio switch. Control could be done through serial commands on the connectors data pins (need an adapter)-great resource might be the ipod adapter which seems to have disappeared from mitchs site: http://www.rush2112.net/mkportal/mod...56b74755c85f16
    2) The other option is to use the iPod as a harddrive and play the audio files off of it directly. DRM might be an issue here depending on where you got your music

    Thanks for the quick reply.

    I dont wanna use analog audio, since I want to be able to controll everything in Windows and I'd have to run another wire. The USB connection I need is already in the front where I need it.

    And also, I would pull the audio files off the iPhone like a hard drive but for one I dont think that is >easily< done (not impossible) and two, wont all of the songs I have synced with iTunes show up as wierd file names? (147fdkslap.mp3)

    you mean to keep the audio as a digital signal into the computer, and then have the computer decode it and send it on to the speakers right?

    as far as i know there is no way to do this...

    i do know that the pinouts of ipods are well documented, and so you could hook up something like aux input using a dock connector--though the reality is that this is really no better than the headphone out, it is just using the dock connector for it...

    edit: a couple minutes late to the party...

    i am not too familiar with frodoplayer--it uses its own player program right?

    All the audio out from the connector is analog. If you wanted to play the iPod through the computer, you would need to pull the files off of it like you mentioned. Yes, they will have silly names that are unreadable, but if you get a program that can read iPods then it shouldn't be a problem.

    As it turns out, the iPod database is pretty simple. For the phones, they're encrypted, but people cracked that a few days after it came out. You just decrypt the main iTunesDB file and theres a listing of all your file titles and where they are stored.

    wow fast responses all around...

    yup like they said iTunesDB is the best way to find out whats what. AFAIK frodoplayer offers no itunes plugin but there is one for a few of the popular media players and probably soon will be for the open source FE's (theres now an itunesdb reader library available under LGPL). One thing I just wanna repeat...like I said above if these are DRM files your outta luck for a digital solution.

    i know for sure that this is not completely true across the board(i think it is true for standard docks though)--pioneer stereos have usb connectors that will play songs from ipods using the cable included with ipods-- and those cables have a max of 5 wires-- +5v, -5v, +data, -data, and ground...

    but i have no idea how the stereos decode/process the audio to get it to the speakers...i am thinking that you might be able to use something similar...

    It's been described twice. The only way of getting digital through the USB is by enumerating the device and parsing the iTunesDB file. Then you open the corresponding MP3 files. It's the only way.

    I believe my factory scion radio also does the digital to analog conversion inside the head unit, but I am not sure.

    Doesn't Winamp have some sort of ipod control? I don't have an Ipod, I just recall seeing something about it.. Or does it not do what I thought it did?
