Develop Bugs

[Q] Increase video and audio recording quality? Build.prop anyone?

So I can't post in the development section yet(I was going to ask in the relevant thread instead of wasting a new one on this question), which I think is a nice rule, but I'm starting to delve into UNDERSTANDING development and how it works. So anyway...
If someone actually checked out this post(which I doubt, since I don't really see people checking the Q&A section) I just wanted to ask, is the build.prop file what I should be looking at for this? I'd like to point out the the EVO 4G has AWFUL audio recording quality, the video I can stand. Just the audio is terrible and totally unnecessary. 12.2kbps at 8kHz is just unacceptable when we have apps utilizing up to 44.1kHz WITH THE VERY SAME MIC that the camcorder uses. I don't know the bitrate for that recording app, but I imagine its at least pushing 96kbps. I used to check "No Audio" and record audio with one app then use the camcorder for video, which was a hassle because then I had to edit the files and put them together.
Yes I know the EVO isn't a GREAT beast(single core processor) but that doesn't mean anything when you got similar phones well within it's realm of spec(DROID, Epic 4G, iPhone 3, etc.) with camcorders that BLOW the EVO out of the water. Why did HTC fail to acknowledge that this was an important issue?!
So enough ranting, my question is simple. The things that are edit-able in the build.prop file include video recording quality and audio recording quality. Does that mean that the EVO's crap camcorder and camera are limited PURELY BY THIS SINGLE FILE? Or, are there other hardware and software limitations that affect the quality?
Lets say that you can dedicate ALL the power the phone has to the camcorder and its software, why should there be a limitation on the audio quality? Why is the audio quality so bad. I see people posting tweaks to increase VIDEO recording quality, and they're done in the build.prop file right? I have no idea how to test if messing with the audio bitrates and frequencies actually work, has this been tested? is that why its ignored? Please someone talk some sense into me! I heard that you gotta do a data wipe for changes in the build.prop to take effect. Is that true? is that why I never experienced differences?
And I really hope I don't get a reply saying "use the search next time" because all I found were VIDEO QUALITY tweaks not AUDIO QUALITY tweaks. Is it because they don't work? or WHAT? and also, I'm rather new to modding, I rooted a long time ago, and flashed a couple mods like a year ago, but recently I've become more interested in HOW those mods work.

There are multiple quality improving methods. Try my smurf tweaks, or xloud and bravia engine. Also there is beats audio u can add it as well. There are was to better ur phone.

Shortly after I posted this, I looked and saw another question asking for a "smurfed out script" and I thought... what the f!? Thanks, I'll check this out and the others you mentioned.
***UPDATE***
Okay, so I looked at those engines and your script. Haven't tried them yet because I don't really want to flash my phone or wipe it right now and they're more for audio and video playback than recording, but I did find a post on Android forums about this issue. Some guy suggested using the LG Camera app. So I checked it out, and I can fidle with the audio quality in there. I never new about this app, but this is EXACTLY what I wanted.
I appreciate your reply though. I probably will end up flashing your script soon, when I have more time. I know this was an old issue, but I had never found a good solution until now.

I know beats audio works. I ran the old eternity rom with the (mod edited) kernel and the audio was brilliant.
Mod edit sorry that kernel isn't allowed to be talked about on xda

? wow really? hmm(thinking about the "mod edited"). only reason I could think of a kernal that's banned in the forum is legal reasons tied to the forum(and a number of mods seem to contradict that reasoning).
I'll try beats, whenever I get the chance i guess, but again, isn't it only for audio playback? the issue I mentioned has nothing to do with the playback of videos, it's the recording. On lg camera, you can change the audio encoding to AAC and mess with the bitrates and the frequency. I have problems on my phone though, the video skips, I think it might be because my sd card is crap, i think its a class 2(its the one that came with the phone) plus its only 8GB. I think I'm gonna buy a 32GB from my friend, I think he said its a class 6, idk how much he wants for it though.

Actually due to gpl issues and with the developer....xda and the developer have come to an aggrement that his name and kernel are not to be talked about or mentioned on xda. In the future I recommend that if you do not know the history or reasons that you not speak about it.

[Q] Audio quality on video recording?

To those of you who have the Note 2 in your hands already, I'm curious what your thoughts are on the mic quality. When recording video, how is the audio? Specifically, imagine recording vid of a live band in a club room.... Is it as bad as previous Samsung mics? Does the Note 2 happen to have built in mic sensitivity settings? Or does it look like it'll require another root/voodoo type setup.
Thanks

Nobody recorded video this weekend?

Bump.

I haven't been anywhere with live/loud music to record (and I imagine others haven't either, hence the lack of responses) but in general usage it seems a little loud so I'm not sure how well it will do with loud music.
For example here's a video I took recently http://www.youtube.com/watch?v=UDb9mE5cpNY (friend gets a bit loud at 1:50)
However I'm not sure if this is a result of the volume mod in this thread or not as I haven't recorded any videos without it.

Ok thanks,
Seems like a very sensitive mic in this video. I was hoping stock would offer more settings for mic control by now. A little surprised this thread isn't getting much traffic.
Voodoo sound is the perfect fix for my current dev. I guess I'll see if that is or will be an option for note2

Here's another video playing music on my really old, ****ty speakers at max volume: http://www.youtube.com/watch?v=PXGOhIz_7eQ
It did a lot better than I expected, coming from my sgs2 (that mic would distort if you looked at it funny)

audio quality when record a vid or a voice notes
Please if u can fix this thing that it will be so amazing .. i need that cuz i love to go clubbing and recoed vid .. also the mic when i record any song on whatsapp (voice note( is awful... im trying to search for a kernel or a mod to fix this ...

I have audio recording problems on Galaxy Note 2
Pops and crackles throught the footage at last night's concert; very disappointing. Would post link to uploaded vid but need to post 10 times before I can do that? attaching link in .txt file
Recorded using:
Samsung Galaxy Note II
Model # SGH-I317M
Android v4.1.1
Any ideas on how/if this can be fixed would be appreciated.

There is an app called (voodoo sound) that fix the sound in the hardware and also the mic . The developer for this app i dont know why he topped working for new devices .. try n.e.a.k kernel and downlod uneak engine from play store .. he is trying to fix this thing .. he just released the new versuon .. it seems doesnt work the mic modes but keep update with him

Sound output increase after JB update!!!

Has anyone noticed the increase in the sound output after JB update? I have seen a massive improvement and the music quality has also improved drastically. Bass is also impressive now. The headphones are now blasting with music... Please share your thoughts...

I have also noticed that the browser does not reload after reopening while multi tasking. These two are the best updates for me in JB...

So multi-tasking is for real this time.
How about music chopping with default player. Haven't read a solution about it before?

Am on the music player for past 2 hrs now, and haven't had any choppiness at all. Although this was an issue even I faced intermittently.

I was also experiencing choppiness in the default music player and Youtube before the update. Now I haven't experienced them so far..

The music player has just become so awesome!! HTC has managed to make gapless play onto to the new update,,which is something that music lovers love the most... :thumbup: And the beats audio equaliser has been redefined,,and music is more loud as well as sharp... I could hear even the smallest of music with my headphones on... Even it did some magic with the speaker.. even though it doesn't have a built in amplifier like the 8x,, it is giving more loudness than before.. HTC has given the best update till yet... :thumbup: Hoping for more..

I feel the better sound too

Browser bug where the status bar keeps showing up once in a while like its going crazy is still there. Its driving me nuts.

absolutely true. i didn't notice a huge improvement concerning music qualitiy though.
loudness increased about an estimated 30%.
what players are you using?
it'S PowerAMP for me.

All sounds amazing thanks for info can't wait for update to reach me. I just wondered, can anyone confirm plz USB OTG is a reality?

Yup USB OTG working..i already try it

I'm using pro player and the stock music player. Maybe the headphones I have are making a difference in sound including the loudness... Glad to know that wifi direct is working...

Yes, I can confirm, the volume is louder with the new Jelly Bean Base

I also confirm, its louder

Rom question

Hi I am new here and have Rooted my sprint note 2 and am running perseus kernel with jellybomb and could not be happier or more grateful for all the hard work you guys have put into these available options for us to use and enjoy.
however me and some of my audiophile friends are having trouble with our usb/dac amps that in a stock SIII seem to work and also work with the verizon note 2 version of the Beans Rom and the cleanrom also for verizon . my question is if I flashed a sprint note 2 with a Rom specifically created for a verizon note 2 what are the problems I might run into ?
thanks for any advice or assistance in advance .

Are you talking volume level or sound quality? Most of the rom builds out there have terrible audio processors build into them
For me (and I sling my music via bluetooth to my rather nice and bass heavy car stereo) can't operate without something like DPS Manager installed and running.
I can connect my phone via anything, BT, USB or headphones and stock (or running any rom) and it sounds like poo. No bass, nada. Equalizer programs help a little, but not much.
I install DPS manager (flash it in recovery) and boom (actually) I have deep, rich bass, good high's and a ton of EQ pre-sets to work with.

all I want is an unprocessed digital signal out via my usb to my portable Dac/Amp ,then I will be in audio geek heaven....
its funny that the SIII and some versions of the note 2 do this well and mine does not ,but if I keep asking people smarter then I am on the subject sooner or later I will get it working.....

Serious bluetooth audio output issue?

I have observed that the bluetooth audio quality in aosp 10 and 9 both roms really sucks it's far more inferior to miui.When the bass is increased the sound becomes supressed and you can hear crackles after every bass punch.Whereas in miui it's powerful and amazing,I have tried everything i can i have changed firmwares china global it;s still the same , i have used several mods viper,dts hpx,dts ultra,james dsp,dolby digital etc. it;s still the same.I hve used music players like poweramp,player pro etc. but the issue persists.Does anyone know what is the cause of this issue and how can it be resolved.The audio quality feels like gingerbread?

Can"t confirm anything like that. I"m currently running a very outdated Superior OS build (August 2019) and listening to the music on my loudspeaker using BT (SBC HD) and wired connection feels the same. No distortions or anything like that (im using retro music player and yt).
I suggest you clean flash the ROM you are currently using and try again without any sound equalisers and boosters

There is a Magisk module that can change bluetooth bitrate, just search for bluetooth and you will find it in magisk repo. Try that but I don't have a problem with bluetooth audio on AOSP.

actually the problem lies with bluetooth earphones and the problem occurs when the bass is increased not when there are no effects applied.

i have used that i increased it to 482kbits but there was no change. I m well aware of the fact that the bitrate in miui is 48 nd in aosp its 44.1.

I think you are mistaking sampling rate (44,1kHz for ex) and bitrate (in kb/s)
While first one can"t be changed, second one depends on the BT codec which your speaker uses. SBC for allows 340kb/s bitrate. In comparison - Spotify non-premium streams in 128kb/s
