Are there no Bluetooth audio codecs for the Galaxy S7/7+ Tablet?

JUMP TO SOLUTION

I'm finding this hard to believe, but I can't get a straight answer on whether there are any bluetooth audio codecs supported for this new tablet besides the poor quality SBC one that is required by A2DP. See https://www.soundguys.com/understanding-bluetooth-codecs-15352/

 

If not, the S7/7+ just went from a definite immediate purchase to a NOT purchase, as there would be no way to get anything but low quality audio to my bluetooth headphones, or any other bluetooth device/accessory. 

 

I'm really hoping that this wasn't a HUGE miss for a tablet that is supposed to be a high end media device and thatbetter codecs like LDAP/Aptx HD and it just isn't documented anywhere yet. 

 

Any decent mobile phone/device (most recent Samsungs, actually, see below) support some form of better audio codec for bluetooth, especially when there is no aux/audio out option, otherwise the only way to get high quality audio to headphones is to use a USB-C cable, but then of course you can't have your device on a charger.

 

It isn't like Samsung isn't aware of this, plenty of their high end devices support up to 5 codecs:

 

5 codecs - https://bluetoothcheck.com/d/samsung-galaxy-s9

6 codecs - https://bluetoothcheck.com/d/samsung-galaxy-note-8

6 codecs - https://bluetoothcheck.com/d/samsung-galaxy-s8

5 codecs- https://bluetoothcheck.com/d/samsung-galaxy-note8

5 codecs - https://bluetoothcheck.com/d/samsung-galaxy-s8-active

 

Please point me to documentation that shows the high quality A2DP audio codecs supported for the S7+ specifically, or at least indicate that there are plans to add them in a firmware update soon so i can buy this after they are added.

like all Qualcomm based devices, it supports SBC, but also AAC, LDAC, and AptX natively, and the Qualcomm audio driver package enables them all when the Bluetooth stack is initialized.

As mentioned above...SBC is a very low quality default option that is required for compliance with an A2DP bluetooth profile.  Any bluetooth audio device that supports A2DP has SBC, and even at the max theoretical throughput (345 kilobits ps) it is about 1/3 of CD quality, with a more realistic, though still optimistic, 256 kbps throughput, decidely lower quality than that. SBC is simply not adequate to stream high quality music, movie audio,  or whatever audio to bluetooth headphones. 

 

AptX is better than SBC, but still not great, so really what is required is AptX HD and this tablet is not listed as supporting it on their site (https://www.aptx.com/aptx-hd), nor is AptX HD listed in any of the specifications anywhere by Samsung, hence my question. Is this supported and just not listed in the specs yet?

 

I have Sony WH-1000MX3 headphones, so LDAC would be a great option here, or for anyone with Sony bluetooth products, inclusing the new MX4s.  Obviously sony is a competitor and there is, of course a license fee associated with adding support, so if it is supported and Samsung paid for it, they typically will broadcast that as a benefit. 

 

As for the qualcomm drivers supporting any/all of these codecs natively, please link me to any documentation anywhere that supports that statement. AptX/Aptx HD and the AptX Adaptive (to replace their current lower quality option) are licensed components. AAC is an Apple product and supported poorly by android natively, though i suppose they could improve that. 

 

I have seen some speculative specification sites include all these codecs, and again, I'd be surprised if they didn't coveral all/most of them, I'm generally a Samsung fan, I just want to get some form of official confirmation first and perhaps some idea of whether these are things that work automatically, or will have to be set explicitly in developer options, etc. There is nothing in any Samsung published info on the tablet that clarifies this.

I have the s7 plus and I'm able to use aptx and LDAC. Interestingly there is an option that says "scalable codec", but no other info.

Can you point me to where the documentation verified this? If the support for those codecs is only part of Bluetooth 5.0, that will be off no use to those of us who already own good headphones that don't have 5.0. 

 

I'm not going to go out and spend $400 on new headphones to get Bluetooth 5.0 to make a $1000 tablet have decent audio. 

 

Why can't Samsung just reply here with which codecs are supported and how, or post it on the spec site. Not that hard.

Where do you see them being used? Is there a setting in the tablet where you can select them?
