camera with stereo recording - Xiaomi Mi Mix 2 Questions & Answers

Hello,
I'm using my mi mix 2 with havoc os 2.9 (android 9), that allows to record AUDIO in stereo, from apps like "hi-q mp3 recorder" if you select "raw source".
As long as I know that this way, this software is using both microphones (one up, and one down) and the recordings are awesome, I want to use a camera that ALSO is able to record audio in stereo.
- Is there a Gcam mod that does that ?
- ... Or any other camera app ?
- ... Or any way to change, e.g., the file /vendor/etc/media_profiles_v1_0.xml to record in stereo ? (already tried to set channels to 2 but it didn't worked)
... And the serious and hard way: I'm a .net + Lua developer, and I'd never made custom roms, so no idea to develop an app in android or even an entire custom rom. I'm assuming that it would be very hard for me to change, debug and made a gcam mod that allows what I want, because, in other words, I don't know where to start ... I prefer a more easy solution.
- Do ALL Android phones follow the same rule to get / set audio configurations ? Is there an 'official documentation' about it ?
Ok, I'm stop asking now (at last! xd) ... Best,
Obsy

Video/ Sound stereo/mono recording

I'm on a HTC 10 full port ( Real Sense 8.0 & 8.0_g (S.Team) DualSim (S.Team) and everything works like a charm. But I found out, that comparing to the stock ROM, when shooting a video, the sound doesn't record in STEREO mode. I need help finding the right place in the system to modify and turn this feature on, please. Stock rom has it on. ALso, where to find the file to modify and make sound recording apps to stereo record also? Device is Desire 816dug ( Dual sim Qualcomm version
@kinghunki , maybe you can help?
please help me
EDIT:
Latest v.3.0.0 S.Team rom works fine with the stereo recording when shooting video. my last question is - how to make our device record stereo sound in Sound Recording apps? Even on stock roms they are mono. What part of System needs to be modified?

our device has awesome recording quality. if give it a stereo breathe, it might become even better. what files of the rom take care of this?

There's a couple xml files in /etc that may take care of it.
Like I said, I'll have to look into it further.

as I remember, someone said, when I was wearing a cyanogen rom. on my galaxy s4, which had stereo recording on stock roms., so that forum member answered my question in this way - As basis, AOSP or Android Original roms don't support 2 mics recording. That's all I know.
thanks for taking an interest on this!

Audio recording lacking bass

Hi, I am running ressurection remix 8.1 on my whyred ai, cant seem to work out how to get any bass on my video recordings, on my mido I had to flash some changes to audio mixer files etc. Not sure if anyone else is having this problem but the audio reoding sounds really tinny.
anyone else notice this?
just realised the inbuilt audio recorder is ok, only video apps like google camera and opencamera seem to have the issue?

Same here I also noticed it. Seems they have a high pass filter at around 150Hz or something.

Ok found a way to get really good audio quality. I've searched across boards and tried a lot of stuff. The volume level might be low(er) but I need to alter another XML file. Good enough for concerts and out in the open I would say.
First you need to change the max bitrate since they set that to 96KHz which is way to low. The file to edit is /vendor/etc/media_profiles_vendor.xml
Almost all the way down that file you see the AAC settings.
You will see
<AudioEncoderCap name="aac" enabled="true"
minBitRate="8000" maxBitRate="288000"
minSampleRate="8000" maxSampleRate="48000"
minChannels="1" maxChannels="6" />
As you see I set it to 288000.
Next is the biggest issue. Seems the MIUI camera standard uses AGC and that high pass filter that up to date I haven't found. Open camera works but the other microphone you can select they go via the noise cancelling stuff which kills the audio and you get an underwater sound.
I have a official licensed cinema FV-5 from the playstore. Now there is an issue for the moment. I cannot record in 1080P (the image zooms in like crazy it seems, I contacted the developer for that). On 4K recording it works perfectly. Also remember in the menu to tab the little shaky hand to switch on the stabilizer as that works miracles.
Now go to the settings - audio - audio source is set to 'built-in mic(video camera)' ------ audio channels - stereo (2) ----- bitrate - 256000 ----- sampling rate - 48000 and very important 'disable audio automatic gain control - is switched on' meaning disabled.
Give it a go.
@junglist @lukesan Hi,
I downloaded Mi Max 3 ROM which is the same SOC and I found some interesting stuff about that!
mediaprofiles.xml in vendor is the same on both devices (at least on 9.5.19.0 which am using right now) but the one in system is different, on Mi Max 3 they changed the aac bitRate in so many lines from 156000 to 192000 which is looks interesting!
Also there’s a trick here, mediaprofiles.xml which is in system is the same media_profiles_vendor.xml which is vendor, same on our device, that means both files must be overriding not only mediaprofiles.xml in system!
here’s a flashable zip from Mi Max 3 ROM for any one wants to give a try, also check out this video which compares between our device and Mi Max 3 regarding this part:
https://www.youtube.com/watch?v=5LKThf9KWjs (09:42)
I still need to perform more testing before I can confirm if this really works or not!

Ok, very cool find! Observations which I made over the last couple of days
We have 2 'issues' on the redmi note 5 (Whyred) so 1) the bitrate and 2) the highpass
1) is as you say media_profiles_vendor.xml we can easily alter that one. Check out the downloadable MI MIX 2 audio quality ... module for Magisk. Download extract and copy that xml file and set the same permissions 644 I believe. Make a backup of the original first. They set the bitrate really high on that one 256kbit/s I believe which is a bit overkill, but compared to 20mbit/s for the video it is nothing and I rather have overkill than 96kbit/s underwater sound.
So that one is easily fixable.
2) The high pass filter seems to be linked to the AGC. I really like the AGC since it keeps the volume constant and should be the standard for the 'normal' people who do not care about extreme hifi things. I would leave it on if I could only switch off the high pass filter. Shoot a video and it will be perfect for 99.999% of the people. Levels will almost be perfect. People easily understandable etc etc etc.
I would like to switch off the AGC (and the filter) for real audio recordings, meaning classical music etc etc .. this involves always having to check if your level is not to low or if the peaks are not to high causing clipping which means distortion.
For issue 2 the only app that I found that can do this is cinema-fv5. I made an error in my previous text to set it to 8MP since then the stabilization doesn't seem to work properly so I now set that to 2592x1296 which seems pretty 16/9 like to me. If you switch off the AGC in this app then you get AGC off and high pass off. Very low level audio but perfect quality. I guess perfect for a concert. (this weekend there is a local festival here so I can really test (and enjoy))
If you want good audio but mono then you need open camera for now. If you set the microphone to 'mono' you will also hear that the sound is good, setting it to stereo gets the noise cancellation working and it sounds like crap.
I'll try those Mi Max 3 things if I find a bit of time. Lets share knowledge and experience and we'll get it working like it should. This is the only small downside of the redmi note 5 that I have found so far. (and that is coming from an S7)
---------- Post added at 10:54 AM ---------- Previous post was at 10:00 AM ----------
@rocker00 Just flashed it. Does set the bitrate to 288kbit/s which is really high but, like said above compared to video that is peanuts. Better a lot more than what it was. But it does not switch off the AGC or high pass. Since you have the rom can you check and attach another file? The file is in the same path (vendor/ etc) our file on the redmi note 5 is called mixer_paths_skus.xml . I guess it might be a bit different on MI MAX but I guess some more audio is being controlled there.
@lukesan First please override media_profiles_vendor.xml manually because it looks like the script is not mounting vendor!
Regarding the file, media_profiles_V1_0.xml, mixer_paths_i2s.xml, mixer_paths_mtp.xml, mixer_paths_skus.xml, mixer_paths_skush.xml, mixer_paths_wcd9326.xml, mixer_paths_wcd9335.xml and mixer_paths_wcd9340.xml
are the same md5! but mixer_paths.xml (which i downloaded the whole rom just to get it in order to try to enable dual speaker) is completely different!
Also i have 2 doubts:
1- in build.prop which is in vendor they changed ro.vendor.audio.sdk.fluencetype to fluence which is none in our device(related to noise cancelling)
2-ACDB (Audio Calibration Database) which is completely different in Mi Max 3 cuz it has dual speaker and two speakers at the bottom, and ACDB is controlled by audio.primary.sdm660.so which is different for sure in both, i hope it's not related to that because it will be really a hard job!
here's the mixer_paths.xml am still looking into it maybe i can find something!

Probably it is taking the media_profiles_vendor.xml which I already edited manually. Well to check that our device is capable you could check with Cinema-FV5 lite which is free up to 1280x720 resolution. Disable the AGC and you get a nice clear sound full audio spectrum. I'm on a 8.7.5 rom and when I start to record my image is taken from the upper left corner all zoomed in. Not sure which rom you are on, but could you give that a try?
If it's that *.so file we need to address someone with the right knowledge. I've never decompiled stuff like that.

BTW, that lib is most likely C++ signed binary so you can't do anything about it!

Just came back from the festival that I told about. The default MIUI video cam.. wow made a complete mess. The AGC went completely crazy and no bass. Using cinema-FV5 ... wow listening to it right now with my earplugs..... it's like I'm still there. Ok the bass sounds (only) a bit distorted, but I was standing at the front and the smart people there handed out headphones that dampened sound to the kids. I myself suffer from tinnitus so I have -20dB earplugs ... even then it was crazy loud.
So cinema-FV5 is definitely a must with music. Not sure if I can upload something on Youtube without violating copyrights. But surely this phone is capable of recording high quality audio for sure.
Same happened to me. After recording the stage with artists and loud music. It looked OK, stabilised video at 1080p, but sound lacks bass with stock camera app.
I would like to try better camera apps like gcam, just there are ~50 hours for me to wait till I can unlock my bootloader and flash a decent ROM.
Then we could record at 60fps 1080p and [email protected] with normal audio.

Forget gcam or other roms for now since they use the same audio path. There is another trick I read about but it involves a lot of work and I would hardly call it a working thing unless you spend a lot of time. Check this thread. I know for the MI MIX but same procedure applies for now. https://forum.xda-developers.com/mi-mix-2/how-to/mi-mix-2-video-sound-recording-quality-t3776450
Leave the 60fps and 4K behind if it is in a dark environment. You might end up with dropped frames etc which is really annoying.

Have you tried it? I've tried your trick with the bitrate increase in media_profiles.xml, though I've set it to 192000 and used the FV-5 disable the AGC and it's much better quality! Although the bass is a bit too much pronounced and the meds and highs are a bit sacrificed, it's still much better than stock. But with the custom settings for audio in FV-5 it makes that "underwater" sound, no matter which combination I used, but I did everything according to your post, only if I leave the default values it works. (I now suspect it was maybe because of the stereo recording option)
I am interested to make some changes using the thread you linked, I'm just afraid not to make a mess of volumes in earpiece or introduce echo during a call or something like that, that's why I'm hesitating.
The AGC makes a total mess of recording, it lowers the quality and introduces background noise.
For the 60fps I'm not sure that works as none of the camera app that I've tried are able to record it (I'm on AOSP based rom) because it depends on the camera blobs, and I'm not sure Xiaomi updated the sources, but they did introduce it in MIUI 10 builds.

Strange that you got the underwater sound. Can you check with this one? https://mediaarea.net/en/MediaInfo Just drag and drop the file on it. It will show the audio properties.
Just to confirm again my settings in FV-5 I changed the resolution to 2592x1296 (turn on handshake thing on where you can actually see where you are recording, weird setting I know). In the 'Audio' settings check the attached screenshot.

Oh yes I did that, but you didn't check the "Custom audio settings" box so the app uses default system settings rather than the ones you selected. Try it out if you didn't already.
And I've checked with MediaInfo, the video was recorded in 96K (because the app didn't use custom settings), but anyway it should be using maximum possible values the device has set in media_profiles_vendor.xml, which is in my case 192K. I've seen now that media_profiles_V1_0.xml is basically the same file and there is 96K set as maximum, maybe both files need to be changed?

That's normal since it seems you can't overwrite those settings in our current roms it seems. I bought that FV5 but I emailed support and never gotten answer back, to bad. It always takes the settings from that file on the phone it seems. And yes if you see 96Kb/s than it is normal that you hear these metallic sounds. Can you maybe attach the media_profiles_vendor.xml you have in the /system/vendor/etc dir?

Well recording in 96K instead of 48K which was the case with MIUI 9.5 in GSMArena test is already an improvement, however I'm sure this device is capable of even more. So for now, seems that just disabling AGC made a very good difference, it might just get better if we raise the bitrate even more. I've seen in the thread you linked that they actually modified media_profiles_V1_0.xml in case of LineageOS to raise the bitrate, I will now try that one as well.
Here is my file you requested.

I confirm that changing the media_profiles_v1_0.xml does increase the bitrate! I have set it to 192K, however since the maximum value that was set for each resolution (I've tested 1080p) is 156K the app used that one based on previous setting. Now every app should use the 156K if we don't alter the bitrate for each resolution separately (that's my guess at least).

I tried this app with the steps you mentioned and yeah, sound is better for sure but it's much better if we can get the same result on stock cam.
let's take it step by step, first is the bit rate, even after using Mi Max 3 files the bit rate remains the same! i checked my old Sony Xperia z2 mediaprofiles.xml and i found the aac bitRate is also 192000, see the video sample result in the 1st pic from sony and second one from note 5 pro!
Now clearly there's something controlling the cam audio beside mediaprofiles.xml since the modifications wasn't enough!
I'll record a log while recording and let's see if i can find any info about that!
@Cirra92 60 FPS is working on 9.5, i thought like you about blobs but surprisingly no! now i'm on 9.5.19.0 and i just got the camera apk from MIUI 10 and i have 60 FPS!
Also i found another thing which is interesting but it's still not working even on Mi Max 3.....looks like 120 FPS HFR is on the way!
Check this video out: https://www.youtube.com/watch?v=0rjZx_5JD1s (13.06)
I managed to get this setting even if it's still grey!
etc\device_features/whyred.xml just added those lines:
<!--whether support camera video high frame-->
<bool name="support_camera_video_high_frame">true</bool>
let's try to make the cam perfect as much as possible!

About sound recording on custom ROM's

On Pie and Oreo custom ROM's audio recording quality is very low by default (96 kbps ), and, which is also important - mono (pseudostereo - technically, in video 2 audio channels).
On Oreo ROM's i can install Camcoder audio quality fix (by rocker00) and will fix it all (patch by nhappyman doesn't fix the sound).
On Pie ROM's - patch by rocker00 breaks the recording from the microphone (patch by nhappyman still doesnt' fix the sound).
It possible to make good sound recordind in video on Pie ROM's?

I know and I don't understand why so little people notice this. Just tried another Pie rom again and I liked it till I noticed audio recording is still in mono and actually only uses the bottom microphone. If people think that 1 camera gives a better picture than another 1000's of people will start to notice and comment on this and multiple threads will be started. This issue ... silence.
For me personally a video recording the audio is part of the deal and if it sounds crap or mono then it is a no go. The mic's on our device are more than capable of good quality audio. I wish I had the time to check the XML files etc again. The fix with Rocker00 took weeks to get it working like we wanted to. I am getting really tired of flashing my phone and not being able to make calls or be available. Sometimes I wish I had a second similar phone where I could just change files, reboot and test over and over again.

Hi-Res output Snapdragon 625

Tested on the lousy zenfone 3 zoom (stock 3.5mm audio sucks inspite of DAC chip because of the poor engine optimization) and it worked like a champ but i believe other devices with SN 625 may benefit from it and they are A LOT, (use 709 build ONLY) other builds won't work as good, i tested them all.
Please do make a feedback on which other device this worked.
Snapdragon 845 devices (e.g. Sony XZ2) – improved Hi-Res Output detection
Sony XZ/XZ1 – improved Hi-Res Output detection
Lenovo X3 – reenabled 24bits
OnePlus (1st edition) – disabled DVC for Hi-Res output due to forced speaker playback
added new per-output option – No Duck – for cases when notification causes issues. Activated by default for Hi-Res output for some Snapdragon 625 devices (Asus Zenfone 3)
HTCs @ 7.0 – improved Hi-Res Output stability
Nexus 6P – fixed notification coloring
Enjoy Hi-Res music all.
Direct download, use poweramp unlocker to activate it.

Can't see any difference on the audio on Poweramp with this option set for active. The audio quality really sucks on this device.

Did you toggle the 'Wired headset/AUX" ? and was your test with headphones or via the loud speaker? and what your headphones are?
This release 709 worked for me gloriously! the only problem that it's not free and needs some work that you can find on youtube or i would post a fellow up about the odds of activating it but i just needed a conformation that it at least made a difference by utilizing the DAC chip on board!!

I've downloaded the apk you uploaded and followed the screenshots. It made zero difference to the sound quality. Poweramp DVC is great on other devices, but on my zenfone it sucks, the audio is distorted, the only way to tolerate the audio quality is by disabling it. Best player I could find so far for my zenfone is Phonograph.

The zenfone 3 zoom have an amazing sound quality and believe me the bass is insane via a good headphones, you just need to find a solution to make use of it's potentials, if you want to go throw troubleshooting provide some more information like the exact model and what software build you are currently running... you are right about the distortion i was very upset with the sound quality at the beginning but poweramp made the DAC work properly.

I wouldn't say that the sound quality on the zenfone 3 zoom is amazing. This DTS audio thing is terrible and makes sound awful. I've installed an even older version of poweramp and tried your solution, and it made a difference with my JBL T210 (not the best one around, surely). However, using Poweramp with DVC on an old Galaxy S6 that I have laying around is still miles better. Sound quality is my only complaint about this phone, that's why I was hoping for a custom rom for this thing.

Yeah you're absolutely right that DTS is a marketing thing and it sucks, you just keep trying on that poweramp 709 build only and try downloading it from APKPURE or somewhere else because the one that i provided was patched with lucky patcher and i hoped it would work with a non-rooted device to skip the activation process but apparently that is not the case, after i reflashed the phone and got rid of the root access i had to install poweramp unlocker and i have to reinstall the the main app every 2 days because without the root i can't seem to be able to activate it, keep digging, i know what a good DAC sounds like, it's not an HTC native level but it's miles ahead of the stock drivers and even better than viper4android module on magisk.

No worries about that. I've purchased the app years ago. The only thing now is that I can't allow it to update. Thanks for the hint, the sound is clearly better now.

How to properly Record Video on festivals?

I cant properly Record videos when loud music is involved. The sound is way too loud and muffled.
Is there any solution to this.
On stock camera and Gcam noice cancellation is being used making it sound even worse.
I found out that in Open camera choosing "unprocessed" in sound options fixes the things a little but still
Unfortunately not really. It seems that they simply screwed up the settings for ACG (automatic gain control) and audio drivers regarding video audio recordings. Most of the Xiaomi devices suffer from that. They do not care about that. It´s such a simple and basic function for a smartphone and I´m sure that hardware used could easily handle high gain audio inputs like on concerts or festivals, but the settings and config they choose to give us simply cripples the device.
It´s a shame really. There is a camera app called Footej Camera that allows you to adjust the input gain settings for video - that could be worth a try.
Also, if you´re rooted and are experienced with modifying system files you could try to modify mixer_path files to get better results. See for example thread: https://forum.xda-developers.com/redmi-note-5-pro/help/audio-recording-lacking-bass-t3814184
