    Does the Note 7 have APTX and what sound chip, DAC does it use?

    Thanks in advance,

    The S7s use a proprietary Samsung chip that does not support APTX. The note will likely use the same.

    This is one area where LG is way ahead of the game with the Sabre chip.

    Saw a post on Reddit that the N7 has the same DAC as the HTC 10. Huge if true. Can anyone confirm?

    Thats same DAC is used in pretty much every Snapdragon 820 device, the differentiating factor with the HTC 10 is the dedicated amplifier they also included which allows it power higher impedance headphones.

    Pretty sure I saw Jerry post somewhere that HTC did not use the snapdragon DAC.

    HTC 10 audio testing — BoomSound evolved | Android Central

    Qualcomm's Snapdragon 820 does a lot of things right, but clear audio isn't one of those things. Something in the digital to analog converter circuit introduces an extreme amount of noise and crosstalk into the analog output, and phones like the U.S. Galaxy S7 and LG G5 sound pretty poor because of this. After doing some testing, I was presented with results that just didn't make sense from the HTC 10 — it was better than it should be, even with extra work and attention to the analog circuit that brings signal from the DAC output to the headphone jack. You can only do so much magic to a bad signal. I asked HTC how they did it, and found out that some assumptions about the HTC 10 audio hardware that the internet (and myself) has are incorrect. The HTC 10 uses a stand-alone DAC as well as headphone amp and isn't using the Snapdragon 820 DAC. This is pretty important, and why the HTC 10 sounds as good as it does.

    Which brings us back to my question as to whether the N7 uses the same DAC as the 10.

    I'm just as interested in knowing this as you are, since my biggest issue with the S7e is/was the average audio quality.

    Hopefully someone can confirm this.

    At least on the S7 you can buy the Exynos version unlocked and get better audio quality among other things.

    The US version uses the Snapdragon 820 referenced above just like the S7 and S7 Edge. The EMEA versions use the Exynos chip with a separate external DAC made by Samsung by the folks who made their Wolffson DACs in the past. They acquirred them.

    When I was in the Netherlands, for work I took some high quality audio with me and played it through the 935F (European unlocked Exynos S7 Edge), and it sounded decidedly better than my US T-Mobile S7 Edge. But the US and EMEA Note 5 and S6 Edge+ (even regular S6) had the Wolffson, which handily beat all of the S7s and was not far off from the HTC 10.

    So unfortunately the US N7's audio will suck. Also, please note that the Exynos versions, while being network unlocked, do not support Voice over WiFi or VOLTE at least for the S7 family. In my case, with T-Mobile's Band 12 LTE being what gives my phone a great signal, this was a deal breaker for using the Exynos versions.

    You can do that Note 7 as well so no difference.

    Should matter for only wired plugged into headphone jack.

    Obviously it's not released yet. It will be in September 1st week as mentioned by Samsung.

    They will start popping up end of August in the usual sites where international unlocked will be available... Just search SM-N930F on eBay and there are sellers taking preorder for end of Aug shipping. They should pop up on B&H, Amazon third party sellers etc SVD various other sites end of August or early September.

    These are available right now on eBay. For a stiff price and no extras. Says delivery next week? Weird

    Edit. Never mind. Preorder. Begs the question why buy a carrier version?

    Assuming this question is in reference to the OP, then yes, for BT audio APTX would matter.

    The snapdragon version uses the built in converter/amplifier. The Exynos uses a superior DAC co-developed with Wolfson.

    Both are 24bit 192khz capable.

    Confusing!

    According to Qualcomm, the N7 is using it's Aqstic codec, same as the new HTC.
    Reportedly, this is a change from the S7 and the N7 is supposed to sound great.

    I'd be surprised if Sammy went backwards from the N5 regarding audio quality. The N5 is crazy good, IMO.

    But, previous posters say they've heard the N7's audio sucks.

    Wonder who's correct on this?

    From what I've read on the Qualcomm page, the n7 will have upgraded audio in the snapdragon version, as they do not mention anywhere of the s7 using the Aqstic codec

    See what happens soon enough I guess

    About the only thing I've been disappointed with in the S7 Edge is the audio to headphones. The original Snapdragon 820 had poor built in audio. Outside of the US, the Exynos version comes with a dedicated DAC made by Wolffson under a new name after they were acquired by Samsung.

    Thanks to the comments section on an article about the Canadian Note7 also using Snapdragon, user @arcane613 reported that Qualcomm had publicised the use of a DAC called aqstic. Between a few of us researching it, it looks like when the 820 was launched, it didn't have aqstic, and even now, it's optional to OEMs.

    Aqstic DAC was launched as an add-on to the 820 on June 2, 2016. Qualcomm in their announcement of the Note7 using the 820, explicitly referenced the use of this "integrated DAC (Digital-to-Analog) converter that supports up to 192-kHz/24-bit playback" in the Note7. This hopefully means that the Note's audio out will far surpass the US S7/Edge, and hopefully at least match the Exynos version, which I compared side by side to my US S7 Edge and found to have far superior sound (using my Bose QC25).

    I hope you're right about improved audio with the Note7. Someone with a test Note7 phone reported the audio is the same between the Note7 and S7 Edge, but I don't know if he/she was just going off the specs or listened to the same things on both phones. If he/she did I'm guessing it was from the phone's built in speaker(s) and not through headphones. Based only on the June 2nd date I would think the Note7 phones would have already been built, and it would have been too late for the DAC upgrade, but hopefully that's note true.
    Guess someone should walk into a place with a demo phone, pair or plug in a set of headphones, and compare the S7 Edge and Note 7 for us. Then we don't have to wait in suspense.

    A point though unless lossless, there is no real sonic advantage. Doubtful even 320K MP3 gets any bennie. Even then you need real good on ear or buds to notice. Placebos are powerful stuff otherwise

    Read the third article I linked to, and search for aqstic. It specifically states that the Note7 is using this DAC.
