Question about Audio (Bit Depth, Sample Rate) - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Hi everyone,
Does our tablet support 24 bit audio? What about sample rates?
I'm on kitkat 4.4.2 and boeffla kernel.

Modify video recording bitrate on AOSP roms?

Hi All,
I was wondering if it's possible to modify the video recording bit rate for the AOSP camera?
I'm currently on v.21 of Paranoid Android which has Google's latest camera with photosphere. I'd love it to record at a higher bitrate than it currently does.
Any ideas on how to increase it?
Kind Regards,

[Q] How to change the sampling rate in Audio Playback?

Hi everyone.
I'm Chinese so my English might be a little strange ,Sorry for that .
I'm using lenovo IdeaPhone K860i and I got the kernel source code some days ago .
And now you can see it at github:
GitHub(dot)com/webore/lenovo
This device makes me mad because the Audio Playback has a 48K smaple rate as we all know mp3 file have a 44.1K smaple rate.
I've tried several times to modify the kernel but I failed .
So could you please help with this ?

[Q] Video Bitrate 100mbit/s +

Hello Guys,
I wanted to ask the team if someone knows if it is possible to push the one+ ones video bit rate bejond 100mbit/s.
I'm currently using cm 12 with camera fv5, which allows recording h.264 4k with 100mbits, which looks really really great. i love the camera of the one+.
is it possible to mod the media profiles or the codec to achieve more than 100mbit? i think the emmc memory would be fast enough, maybe the cpu wouldnt do it.
maybe someone can explain me where the limit resides?
as far as i know, there is NO other smartphone capable of 100mbits DCI recording, i also couldnt find a digital camera doing this at 30fps.
thank you very much,
regards,
christian

UHQ Upscaler and BT

Hey has anyone gotten UHQ to work on bluetooth? I just got in the update and it enables when I plug my headphones into the phone but not when connected via BT. Thanks

Not entirely sure if BT can support the bitrate requirement for UHQ. BT isn't really a data heavy protocol.

Okay thanks. Yeah I know BT isnt great for HQ but I guess I was under the impression that the tweaks would work on either.

To use UHQ on bluetooth connectivity, you must have a compatible Bluetooth Headphone. Check out Samsung Level On Wireless Pro.
Samsung Level on Pro with S7 EDGE
I am currently listening to 24\192 tracks on my S7 edge with PowerAMP alpha and a bluetooth attached Level on Pro. I had my doubts when I read the specs but it is extremely likely that it works for this combination of hardware and software . UHQ via Bluetooth does work.
Galaxy S6 (S6 Edge, Edge+) and S7 (S7 Edge) support UHQ-BT codec developed by Samsung (don't mix with Samsung UHQ upscaler used in stock Music application). This codec allows audio transmittion via Bluetooth 4.0 at a pretty high resulution: 24 bit / 96 kHz (2 channels stereo). In order to be able to use this feature you must use Bluetooth audio device, which supports this codec, for example, headphones Samsung Level series. In order to enable UHQ-BT you need to download the application Samsung Level from Google Play Market and make sure that "UHQ" is enabled. 24 / 96 is the TOP possible limit of UHQ-BT codec for a pair S7 (S7E) + Level headphones. Of course it also depends on the audio file (stream) you're trying to play. If the file itself has low audio resolution with high compression then you cannot get high audio quality. The best audio quality will be when listening to audio files in lossless format (such as flac) with resolution 24 bit / 96 kHz. But there's also a question of how such high resolution was created. One thing is it was made from the original studio recording (made in 24, 36 or 48 bit resolution on professional equipment). And the other thing is if the source for lossless 24/96 audio file was a crappy mp3. A special case would be some vinyl-rip made by an enthusiast on some high-end analog - digital pair. You can find them with resolution as high as 24/192. But most of the time you get some background noise and vinyl crackle. So, the point of such high resolution for vinyl rips in the first place is rather doubtful in my opinion... Also, since UHQ-BT top capability is 24/96 audio resolution, there's no point in using 24/192 for our pair (S7 + Level headphones) UHQ-BT will downscale it to its 24/96 anyway... Other high-res BT codecs available: aptX HD, developed by Qualcomm, which supports HD audio with resolution 24/44, which is a little lower than UHQ-BT. Standard aptX supports CD-audio with resolution up to 16/44, which is even lower. Samsung Galaxy S6 (S6E) and S7 (S7E) support aptX, but do not support aptX HD. If you have a BT audio devise, which supports aptX and are unwilling to get Samsung Level series headphones (Level U, Level U Pro, Level U Pro ANC, Level On, etc...) then aptX supported quality with 16/44 resolution is the highest possible that you'll get. And if your headphones do not support aptX then you will get even lower resolution. The bottomline is get Samsung Level series headphones, if you want to get the highest BT wireless audio quality.
Now, as far as Samsung UHQ upscaler, which is built-in in the Samsung stock Music application, this is a feature, which increases audio resolution programmably. This helps to get the audio sound a little "more smooth" compared with original low-res quality. It removes to certain extent the "digitalness" of the sound, "making connection" between sound "dots" smoother. But it cannot make up high frequency sounds between dots, which may be lost due to low resolution and/or high compression. It simply "doesn't know" they existed.
Hey guys. I swear when I say this that I had a S6 for 2 years and the old samsung music app allowed to enable the UHQ mode even when connected to standard Bluetooth headphones and scrappy speakers started aounding great. In fact I was just surprised at how much of a difference it made. But I updated the app and since then have never gotten it to work over Bluetooth. It still works for wired headphones. But honest to good this feature actually worked and made no difference to which speaker it was connected to.
So I am pretty sure there must be a way to get it to work it is definitely a software matter. I am sure some of you smart folks can figure it out.
What if?

What if I have the S7 and Samsung Level wireless headphones along with the Samsung Level App and the uhq upscaler still is not accessible?
Hi,
Samsung's own UHQA BT audio codec, such as APTx HD or LDAC, has a link bandwidth of 24/96 (512 kbps), but when I connected my Level u pro to my S7 (Exynos) and check it from the developer's menu, it connect with scalable audio codec 16/44. (256 kbps). And I can not change it. in this case 24/96 flac music quality is reduced to cd. Can someone who knows explain?

Poweramp 16 Bit Output for Direct HD on Viper4Android

Hello, Poweramp output results into 16 bit rather than 24 bit when using the Direct HD for output.
This is due to Viper4Android set as my MusicFX for Poweramp [ happened on LineageOS 16, Pixel Experience and Resurrection Remix 7.0 Roms].
If disabled the output is 24 Bit.
Any idea how to obtain the 24Bit when using Viper4Android ?
