    Has ATT activated HD audio on their network yet? Ppl say they can hear me much better on my 5S on ATT vs my 4S on Sprint. Maybe cause Sprint just sucks?

    It's not that HD audio per say. CDMA radio for voice suck in general even compared to WCDMA voice. But CDMA radio for voice usually handle cell phone tower congestion and handoff better than WCDMA.

    iPhone 5 and 5S have better noise cancellation and microphones than older iPhones. That could be part of it, too.

    When does ATT plan to release HD Voice? I saw that there was a hack that enabled it that came out this summer. Any idea on an official release?

    I'm not sure if it's HD Voice or just iPhone improvements but I recently moved from a 4S on AT&T to a 5S on AT&T and the voice clarity is perhaps the most noticeable improvement. Callers are much, much clearer and people can hear me better too. It's a welcome improvement for sure.

    I think it's definitely due to this^^^!

    I'm still on Sprint, but have had several people notice better clarity with my 5s and they aren't hearing background noise.

    I think they said they would launch it by the end of the year, which for all we know could be at 11:59pm on Dec 31st :rolleyes:

    It depends partly on their handset vendors because although network infrastructure is required to do HD voice, the phones have to support it, too. So it wouldn't make sense to launch until enough of the installed base can take advantage of it. I don't know what the 5, 5S or 5C have in that regard.

    All three support HD voice. So do the Samsung Galaxy S III and S4. that would make for a big enough userbase, IMO.


    The CDMA vocoders (used on Sprint and Verizon) have a lot to do with it. They sound way "muddier" than the GSM/UMTS vocoders.

    I have received feedback that call clarity is better on 5S vs 4S. The noice cancellation microphone on 4S was on top whereas 5S has it in the back, next to rear camera and LED flash. Certainly seems a better position for noise cancellation.

    I don't know if call clarity is better on 5S vs 5.

    As an aside, Facetime Audio is freakin' crazy clear.

    It's almost spooky. It's like whomever I'm talking to is right next to me talking right to the side of my face.

    Is it confirmed that the 5s and 5c have all the necessary components to support HD-voice?

    I thought that has been a feature since the original 5. I doubt they removed it for the 5c/5s. The main thing is waiting for the carriers to support it, and then there are issues with HD voice being supported in calls between people on two carriers.

    Just a reminder that FaceTime audio sounds even better than HD voice calls and work between carriers if both ends have iPhones running iOS 7.

    So if your friends have iPhones, call them with FaceTime Audio! The audio quality is so good it sounds like you're standing next to them.

    Agreed. Use FaceTime Audio if your friend has an iPhone. Sounds really awesome.

    Agreed! I thought this was a stupid feature in iOS 7 but I tried it last night for the first time and WOW! It made me a believer and now it will be my prefered method of calling my other iPhone friends and family.

    The only drawback, aside from the other party needing an iOS device, is there seems to be a slight lag. But it's worth it to actually understand the other person. When talking with Dish Network support a couple of nights ago, the lady might as well have been talking through a layer of cotton balls.
