    Not sure if this needs a Bluetooth radio change. But if it is just a software update, does anybody know if its supported in upcoming IOS 7 ?

    I believe it's just a codec that apple could add, but they probably don't want to pay for the licenses. OS X supports it so maybe one day?

    It would be a significant fail if they wouldn't add even in iOS7 (up to beta3 I think not yet, unfortunately).
    With all of that 30pin old sound docks installed base... and the fact tha Apple was reinventing music... well it would be an epic fail, more than significant... :eek:

    No, not an epic fail.

    Transcoding lossy AAC to lossy APTX is a fail for 'reinventing quality music' and goes completely counter to Apple's goals, or mine.

    Transcoding AAC files that are already present, uses more battery than transmitting natively.

    If you want good quality BT headphones. Get some that support AAC native with no lossy-lossy transcode.

    It can be done in software, but I'd be kind of surprised (although pleased) if apple added aptX support. Keep in mind that Android itself doesn't have aptX support, either. Some Android OEMs just add aptX support in after licensing out the codec.

    I'd be surprised if they added it as well. They support AAC over A2DP, and they figure that's probably enough. There's also the fact that since they have to encode on the fly, they might as well use the codec they've got realtime encoding support already, especially when the iPhone has a hardware encoder/decoder for it.

    With it in hardware means more performance when doing the transcoding in the background, and a smaller effect on battery life. Don't really get those benefits with Apt-X on iOS right now.

    I thought they already did support Apt-X? I recall reading about support being added way back in the days of iOS 4 or 5.

    Apple's been doing some stuff with AVRCP at that time, and they made some tweaks to the bitrate used in iOS 4 for A2DP. They've never supported Apt-X though. AAC is also an optional codec outlined in the A2DP spec, while Apt-X is not. Apple already has an AAC license, they would have to license Apt-X on top of that.

    There's plenty of reasons for Apple to avoid Apt-X if they can, including cost, performance, and battery life. Although I'd note that the codec support in the A2DP device market is very poorly communicated to the customer. At best, you might find it in the manual. Although the Apt-X guys are very good at getting their partners to advertise their support of the codec. It does help make the case for Apt-X, in that it is easier to find a device that supports it, versus finding one that supports AAC.

    Ciao Menel, you are right: lossy to lossy is unwelcome...
    Nonetheless APT-X supports lossless encoding (96/24), too. Or up to 1Mbps multichannel lossy (not so distant from DTS).
    The real problem - I agree - is to find an AAC compliant "dongle"/receiver that I could use for sound docks or to connect in my car for hi-quality music (to AUX stereo).
    Currently I've tried an Auris btooth receiver but... A2DP plus a (probably) cheap DAC gives a terrible result.
    Now I'm using Airplay (Airport Express) with an external optical DAC (Musical Fidelity VDAC-II): light-years ahead... Excellent music, finally.

    You get multiple, can stream to them simultaneously using iTunes and your library. Also the Remote app.

    3 of them. Front deck, rear deck and pool, and AppleTV in den. Synchronized and high quality music synced across entire hone.

    Have you tried viseeo tune2air. It has AAC and a decent DAC. You can also get an aux adapter for it.

    There are some headphones that support both aptX and AAC. Search "aptx AAC headphones" to find them.

    I use the ViseeO Tune2Air adapter in my Mercedes with the 30pin cable in the glovebox. What a great little device this is. Works perfectly to allow good sounding A2DP Stereo BT in my car with my iPhone 5 and also connects to my MB Bluetooth for my calls. Best little device I've purchased in a while (the tiny Kokkia apt-x 30pin adapter is outstanding as well and works perfectly with the Apple Lightening to 30pin adapter for apt-x to apt-x with Apple devices)...


    Amazingly, Beats Wireless support both :eek: LOL
