[Q] Nexus rear microphone?

Though Nexus 7 has two microphone, however I noticed that the mic on the left has never been used to record audio in any app, even stock camcorder record mono audio stream from the mic on the top.
Choosing "rear mic" in recording apps doesn't work as well.
So how does it work ? Is the problem of Android API or hardware?
Sorry for the missing 7 in title(๑>﹏<๑)

i might be making a another face-palm here. but i think the bottom is for portrait mode and the top one is for landscape mode?
it could also be that one is used for recording and the other for noise cancellation? switching between the two while in use could be posing the problem?

Hardware is quite good
ALC5642 should be an HD Audio process chip, and it works really well in Ubuntu:

Directly record audio from two mic with arecord with channel>1, I got 32bit float, 192kHz PCM stream
For 4 channel, I got FL,FR, C(???where does it come from?) and an empty sream
FL=Left mic
FR=Top mic
The quality of recording and playback in Ubuntu is much better than Android :good: ,a simple command of
Code:
arecord -c2 -f U16_BE -r48000|oggenc -o recording.ogg -q 7 -
gives a better recording quality than most of apps in Android.

Best audio setup for simple car audio/speakers AUX?

Hello xda,
I, as I imagine many other people in this forum, love hearing my music while driving. It's soothing, makes the ride easier and all in all can be a great experience. However, things can always get better.
I'm using my Galaxy Note 3 along with Poweramp music player and no additional SoundFX or anything. Poweramp is adjusted in the "Bass and Treble" preset, bass is halfway up, treble is 3/4 and StereoX is halfway up as well. Sound is pretty nice and bass is nice as well, however, I feel that the sound could be waay better than what it currently is, I love a nice, booming feeling bass (none of that cracking bull) but it lacks in that department.
My car has a simple radio with AUX entrance and 4 pretty normal speakers, I know this will certainly limit my experience and I currently do not have the resources to improve this aspect of my audio, but I was wondering if anyone here had reached a good setup or preset for listening music in your car's audio that you would like to share. I would be very glad to hear about your experiences and current setups.
SoundFX apps, Music player apps, Equalizer presets... all that stuff. I'm looking for a nice clean booming bass and clean trebles, not interested in distortion or drowning the higher pitched noises in exchange for lows. Share with us!

Just in case anyone came across this thread and was interested in improving the sound experience of your low-end car audio system. I found a very good mix for my phone. Clean punching bass and great treble. Remember that most likely it will not sound the same in your vehicle due to all the variables involved. But give it a try nonetheless.

Used PowerAmp. Equalizer is FLAT, bass and treble 1/3 way up. No StereoX. Limit enabled. Remember to disable direct volume control and enable musicFX in Poweramp.
When playing music, go to Viper4Android, go in menu and tap "Driver Status".
In processing it must say Yes. Otherwise, V4A is not working. Try enabling compatible mode and rebooting.

Google Play Music Equalizer Settings

Hey all. I wanted to make this thread for us audiophiles to share our Equalizer settings through the Google Play Music app and give people some general guidelines for optimal sound settings. While there is no real format to this, if you decide to contribute, please try to include:
Headphone type (earbuds or headphones)
Brand of headphones/earbuds (if you can)
Type of music
Screenshot of settings
For me, I listen mainly to metal and hip hop. And when I say metal, I don't mean Judas Priest or Black Sabbath. I'm talking about the newer generation of metal with weird noises and breakdowns (ALL THE BREAKDOWNS). I want my music to be as heavy as possible, so I lean more towards heavy bass and cranked treble which offers extremely clarity to the instruments. The vocals take a bit of a hit and almost get drowned out, but I'm still trying to find a way to balance everything. If there are any fellow metalheads here, please feel free to help out.

In google play music there was a beep sound in between the songs.and songs change automaticaly.please help me to resolve this problem...my mobile is moto g4 plus

"newer generation of metal with weird noises and breakdowns "
That's not metal... That's mallcore.
But anyway, my settings depend on which earphones I use. Usually, I go for a scooped setting, the mids are set to flat or a little below. If I use my AKG Q460 I might even turn of the EQ, since they are more balanced than in ear headphones.
My bass boost is set at maybe 1/4 and the surround is off.
Other in ear phones I use are aJays 5, Samsung HS3303 and Motörhead Overkill. The aJays and Overkill have a bit more treble than the Samsung ones which I find more balanced and they fit better in my ears as well. But right now I go with the aJays.

Being a bit of an audiophile myself. I am very happy using Viper4Android cabled to my headphone amp. I keep the settings simple enough not to drastically change the sound but to enhance my experience with my IEMs.

Why does OxygenOS look washed out?

As the topic implies, why does it? It looks washed out vs any other CM based rom. I've ran the unofficial CM12.1, Exodus, Temasek, you name it, and they all are noticeably more "colorful". Not even the new color balance option can seem to help OxygenOS . Is there something that can be done to try and fix this (like using the same gamma values of CM based roms on this one via app, etc)?

I used boeffla kernel and these colour settings. The change is huge versus stock.

Okay, so yesterday I received my JBL t150 earphones for my #OnePlus2 and the sound quality is incredible. But I am facing one issue. The button on the mic is not functioning properly. Like I inserted it for first time it couldn't play/pause music or take calls. I used it on other device it worked fine then again tried on mine it then started working(not on play music tho) then I sync my accnt on play music and the play pause feature started working fine(even in mx player and es media player). But after i plug it out and then plug in again the button play pause feature doesn't work. Then I try it few time, still doesn't work. Then I restart my device and use it again it worked fine but again I unplugged them and plugged in again and again the play pause feature doesn't work. Sometimes even after restart it doesn't work until after few minutes. So i think it's either compatibility issues or something with the OS? Because earphones work fine in my sis LG device. (korean model) . Guys, please help.

[VIPER4ANDROID] CleanAir - Universal Viper4Android profile for Apple AirPods

Oi, mates!
After browsing the interwebs for a couple of days in order to find a good Viper4Android profile for Apple AirPods, I ended up empty-handed so I decided to make my own profile aiming to be universally better with as many different genres of music as possible.
As usual, here's a warning you likely won't read:
I am not responsible for your damaged AirPods, ears, phone speakers blowing up or if your software decides it doesn't like you. If you come here and tell me I broke something of yours, I'll tell you to sod off. You're responsible, not me.

Having that out of the way, let's get into the details because that's what you came for anyway.
The profile is the result of a couple of days of adjusting and fine-tuning the Viper4Android Bluetooth profile so it matches the AirPods. While AirPods are similar in design to the old, wired Apple EarPods, the hardware differs greatly making old profiles obsolete for the modern hardware. If you still want to use this profile for EarPods or other hardware, go ahead but it will likely sound like ****e as this is a very specific profile.
I've tested this profile numerous times with everything from Vocaloid music to polish Disco Polo and out of 135 songs only 2 sounded odd in some way making this a very universal profile that should work for most people.
The profile mainly adjusts the equaliser as well as Viper Bass and Viper Clarity, but it does have some other settings to give the sounds a bit more "oomph". You can play around with the settings but I don't think there's much more that can be done as I really played around with everything possible and any changes just make it sound worse in my opinion, but you may disagree and it's your device after all so do as y'all please.
To get the best effect out of your AirPods make sure to disable absolute volume in developer settings, otherwise, the headphones will be very quiet. I also recommend AirBattery which doesn't affect the audio quality but fills in the gaps regarding functionality with AirPods on Android. Check it out for yourself.
Lastly, enjoy.

Do you have a profile for V4A 2.7? Or screenshots of your settings to recreate the profile?
