[MOD][ROOT] Stereo Audio Recording

Flashable zip files kindly offered by @springer.music
Lollipop
Marshmallow
Nougat <= 7.1.1
Nougat 7.1.2
In spending a lot of quality time with audio on the Nexus 5, I found a way to enable stereo recording that, with only minor modifications, works
also on the Nexus 6. Let me preface the below by saying that I do not have access to a Nexus 6, but @springer.music was kind enough to work
with me throughout the testing phase. Thanks!
On to the details:
The Nexus 6 has three microphones. The main microphone sits behind the lower speaker grille. The other two have their ports open toward
the back of the phone, i.e. one of them near the USB port and the other one near the camera lens. For camcorder recordings, the Nexus 6 uses
the front microphone by default.
This mod changes two system files, i.e. /system/etc/media_profiles.xml and /system/etc/mixer_paths.xml.
While the changes in media_profiles.xml simply enable two-channel processing, the more interesting changes occur in mixer_paths.xml.
After some experimentation, we have found that the microphone close to the USB port is associated with ADC1 (channel one of the analog-to-digital
converter in the audio codec), the microphone close to the rear camera is associated with ADC4, and the main microphone is associated with ADC3.
The mixer file now contains a new audio device called camcorder-stereo (only called when the "camcorder" device is requested) that uses the
microphone by the camera lens as the left channel and the microphone close to the USB port as the right channel. The gains are kept at stock
camcorder levels, i.e. ADC1=ADC4=8. These gains are by no means set in stone. You can adjust them as you like, making the microphone more or
less sensitive in the process. Indeed, you may need/want to do that when you plan on recording, say, a club visit or rock concert.
Keep in mind, though, that you need to reboot your phone anytime you make changes to the mixer_paths.xml file as
the new values are read only upon a system boot.
Welcome side effect: In addition to the camcorder now being able to capture stereo audio, all audio recording apps that allow the microphone
to be changed to the "camcorder" microphone (provided the app itself offers stereo processing) can take advantage of this mod, too.
Apps that are capable of recording stereo audio with this mod are "Voice Recorder" and "Easy Voice Recorder Pro".

Any idea if Viper4Android makes any changes to these files that this mod will overwrite?

Possibly. I would install Viper4Android first and then consolidate the two mixer_paths.xml (and maybe media_profiles.xml) files manually.

Installation:
make a backup of your stock media_profiles.xml and mixer_paths.xml files (attached in the "stock" archive for convenience)
manually push the two files in the "stereo_mod" archive to /system/etc/
adjust the permissions of the two files to 644 (rw-r--r--)
reboot
@springer.music will be providing a flashable zip soon for those of you who don't feel comfortable pushing system files manually.

Use All three MICs
Hi chdloc,
Thank you so much for your post! Really helpful!
Based on your work, I wanna make some change------using all three MICs(including camcorder, the mic near USB in the back, and the default mic in the front). I wanna keep your revised media_profiles file. Just make some changes in mixer_paths file.
Like this:
<path name="camcorder-stereo">
<ctl name="AIF3_CAP Mixer SLIM TX3" value="1" />
<ctl name="AIF3_CAP Mixer SLIM TX5" value="1" />
<ctl name="AIF1_CAP Mixer SLIM TX7" value="1" />
<ctl name="AIF1_CAP Mixer SLIM TX8" value="1" />
<ctl name="AIF2_CAP Mixer SLIM TX9" value="1" />
<ctl name="AIF2_CAP Mixer SLIM TX10" value="1" />
<ctl name="SLIM_0_TX Channels" value="Two" />
<ctl name="SLIM TX3 MUX" value="DEC4" />
<ctl name="SLIM TX5 MUX" value="DEC4" />
<ctl name="SLIM TX7 MUX" value="DEC3" />
<ctl name="SLIM TX8 MUX" value="DEC6" />
<ctl name="SLIM TX9 MUX" value="DEC3" />
<ctl name="SLIM TX10 MUX" value="DEC6" />
<ctl name="DEC6 MUX" value="ADC1" />
<ctl name="DEC4 MUX" value="ADC3" />
<ctl name="DEC3 MUX" value="ADC4" />
<ctl name="ADC1 Volume" value="8" />
<ctl name="ADC2 Volume" value="0" />
<ctl name="ADC3 Volume" value="8" />
<ctl name="ADC4 Volume" value="8" />
<ctl name="ADC5 Volume" value="0" />
<ctl name="ADC6 Volume" value="0" />
</path>
Is that ok to use all three MICs for recording in the same time?

I'm not sure what the (even theoretical) benefit would be to use three microphones simultaneously for camcorder recordings. Two of them are relatively close together, so there would be very little additional spatial information. As a use-case I can only come up with using the front microphone to pick up narration, but there will be a lot of cross-talk between the channels (if that use-case is desired then it may be better to attach a separate close-talking microphone to the headset port). Plus, in order to play back the recorded audio you would need to implement some sort of 3 ch->2 ch down-mix paradigm. (Unless you use the three microphones to design a steerable first-order or even second-order differential microphone array for a more flexible acoustic front-end capable of recording spatial sound)
Theory aside, in the "camcorder-stereo" device in mixer_paths.xml you would need to change
Code:
<ctl name="SLIM_0_TX Channels" value="Two" />
to
Code:
<ctl name="SLIM_0_TX Channels" value="Three" />
if that is even supported by your device. Also, you would need to update /system/etc/media_profiles.xml to support not two but three channels. Then the questions is whether Android (libaudioflinger) knows what to do with three channels. I don't have a Nexus 6, so I cannot test.

Firstly, many thanks for your reply!
Because we are working on speech enhancement algorithms, three MICs recording is much better than two MICs even though that two MICs are close to each other.
I used the revised mixer_paths.xml then tired
<ctl name="SLIM_0_TX Channels" value="Two" />
and
<ctl name="SLIM_0_TX Channels" value="Three" />
with camcorder stereo recording. But the results are the same as the normal two MICs recording instead of three MICs. Only the camcorder and the MIC on the back near the USB port working. My guess is that, there will be a file to state how to store recording data from two MICs into one buffer (Like two MICs stereo recording is left right left right...). So if we want to do three MICs recording we have to find that file and revise it to make it be able to store recording data from three MICs into one buffer.
Based on your experience, what do you think?
Thanks again and best regards!

For camcorder recordings -- as I alluded to before -- in addition to modifying mixer_paths.xml as you did above, you also need to modify the file /system/etc/media_profiles.xml. In that file, change
Code:
<EncoderProfile quality="720p" fileFormat="mp4" duration="30">
<Video codec="h264"
bitRate="12000000"
width="1280"
height="720"
frameRate="30" />
<Audio codec="aac"
bitRate="96000"
sampleRate="48000"
channels="1" />
</EncoderProfile>
<EncoderProfile quality="1080p" fileFormat="mp4" duration="30">
<Video codec="h264"
bitRate="17000000"
width="1920"
height="1080"
frameRate="30" />
<Audio codec="aac"
bitRate="96000"
sampleRate="48000"
channels="1" />
</EncoderProfile>
to
Code:
<EncoderProfile quality="720p" fileFormat="mp4" duration="30">
<Video codec="h264"
bitRate="12000000"
width="1280"
height="720"
frameRate="30" />
<Audio codec="aac"
bitRate="96000"
sampleRate="48000"
channels="[COLOR="red"]3[/COLOR]" />
</EncoderProfile>
<EncoderProfile quality="1080p" fileFormat="mp4" duration="30">
<Video codec="h264"
bitRate="17000000"
width="1920"
height="1080"
frameRate="30" />
<Audio codec="aac"
bitRate="96000"
sampleRate="48000"
channels="[COLOR="Red"]3[/COLOR]" />
</EncoderProfile>
and change
Code:
<AudioEncoderCap name="aac" enabled="true"
minBitRate="758" maxBitRate="288000"
minSampleRate="8000" maxSampleRate="48000"
minChannels="1" maxChannels="1" />
to
Code:
<AudioEncoderCap name="aac" enabled="true"
minBitRate="758" maxBitRate="288000"
minSampleRate="8000" maxSampleRate="48000"
minChannels="1" maxChannels="[COLOR="red"]3[/COLOR]" />
followed by a reboot.
You may not need to modify media_profiles.xml if you find an DAW app (or write one yourself) that is designed to work with more than two channels and that uses the "CAMCORDER" device when setting up the audio subsystem. You could also look into using ALSA directly from the command line to try to capture all three audio channels simultaneously.

I've updated the file generously provided by springer.music to contain the modifications to Android M Preview 3 stock files to enable stereo recording. I've attached it.

Thanks zefie.
I've been playing around with with the input gain in mixer_paths.xml and after a numbers of tests I then changed the ADC1 and ADC4 values to "0" instead of "8" on my Note 6 (the zip file I posted in my previous post had the input gain set to "8").
I discussed this with chdloc some months ago and he told me that "8" should be the default value. However, with ADC1 and ADC4 set to 8, I used to get some unwanted audio clipping (it sounded like some sort of limiter kicked in, it was not distortion due to saturation) with high volume audio sources, such as live music and the like.
Setting ADC1 and ADC4 to "0" seems to provide more balanced results.
Here's a new/alternative zip file for Lollipop/5.1.1 with the ADC values set to 0 if anyone would like to try it.

Unfortunately, without having access to the codec's documentation, only experimentation and measurements can determine what the default value "should" be. Without having access to a Nexus 6, all I can say is that "8" was the (default) value chosen by the Google and/or Motorola guys.

You're right, the trial and error method can quite often be the best solution.
Still, I don't understand why stereo audio recording is not a standard feature on the Nexus 6. The mics are there and they seem to work decently. Go figure...

Working really well on the m preview rom , thanks!

HI everyone. Any idea how can we increase the sound volume in our A5 2016?
Many thanks.

I've modded all my devices so far to have very loud volume but so far i had no succes in finding to make this one louder
It should go like this :
The sound settings for modding is in \etc\mixer_paths.xml & \etc\mixer_paths_rev08
You can open this with root explorer (long press and select open as text) or copy to pc and edit with notepad+ for faster editing.
You will find inside (about halfway)
<!-- Output volume stage -->
<!-- media playback volume -->
<path name="gain-media-handset">
<ctl name="S2801 MIX1_LVL" value="0" />
<ctl name="DAC Gain" value="127" />
<ctl name="Earphone Volume" value="0" />
</path>
<path name="gain-media-speaker">
<ctl name="S2801 MIX1_LVL" value="0" />
<ctl name="DAC Gain" value="127" />
<ctl name="Speaker Volume" value="0" />
I tought volume would change if i change these values, the sound would be louder (as it is in other marshmallow devices) but both changing "127" & "0" to a higher number made no difference.
I'll keep you updated if i find it (or if somebody else with a little more knowledge can help out it would be higly appreciated

Hi thanks for the tip, but it enhances the sound to give better listening experience that indeed sounds a little bit louder (like in XM player) but i search to modify a setting in A510F to give (much) more volume to the speaker or headphones (like for example this old mod )
Normally it is easy but this device i did not find it yet

there is also a mixer_.paths_rev08.xml and i edited that one also but no luck.
I hope someone finds it because i am not used to have a phone with no volume mod It's no use to install an app that give a boost to play music or media louder inside the app itself because that does not make alarm or incoming calls louder (etc)

Try this.

Increase Volume via mixer_paths.xml

Hey guys, so after rooting, no matter how much I edit these values in the mixer_paths.xml (in systems/etc) my phones headphone volume remains the same:
<ctl name="HPHL Volume" value="20" /> (originally 9)
<ctl name="HPHR Volume" value="20" /> (originally 9)
<ctl name="RX1 Digital Volume" value="85" /> (originally 84)
<ctl name="RX2 Digital Volume" value="85" /> (originally 84)
Has anyone had any luck with increasing their volume on a Nokia 5?
Cheers

I am just looking into it myself. First thing I didn't like is that there are over 20 files named "Mixer_paths_*something*.xml", unlike my last KK phone. Clearly the settings for various things have been spread through various files. There is a lot of crap in Nougat that is worse than what it was in KK, and this is just one of those things they insist on calling "progress".
Anyway, the section you post isn't the right part of the file to change settings for this, at least it wasn't in KK days. That's "initial mixer settings" section, and we need "headphones" or "speaker" section. But the problem is this:
<path name="speaker">
<ctl name="RX3 MIX1 INP1" value="RX1" />
<ctl name="SPK" value="Switch" />
</path>
That "Switch" value was a NUMBER, which we used to change and therefore obtain louder sound. I have no idea what value is given to "Switch" variable and where to find it, but that's what needs to be changed. Maybe.
Unless the right setting is in one of the other files, in which case we have to edit 30-odd files... which I'll try if I have to, when I have the time.

There are actually 20 variously named "mixer_paths" files, and editing ALL OF THEM makes no difference. Viper4Arise installs and runs, but makes no change to the sound at all.
I suspect that another equalizer is running and preventing us from getting a higher volume. Some people mention "MusicFX" and Dolby, but neither of them show up in my dock or list of apps.
I tried uninstalling Dolby through Titanium, but it says it can't find the apk file. Renaming 17 or so files with "Dolby" in the name causes the bootloop.
So I don't know. I don't have much hope for a solution, this isn't a very popular phone at all.

Can someone test out my mod?

Just tell me if it works or not. Any contributors are credited.

You can adjust the volume in mixer_paths.xml under "earpiece" section, it's somewhere on the lower half of the file. When you find it, change the volume in "RX0 Digital Volume", but don't change it over 100, you'll damage your earpiece. And please let me know what your safe volume is.

Yeah, because the earpiece isn't used as a secondary speaker from the factory. Therefore, the Earpiece is a lower quality one. So, it's not made to be a secondary speaker. If you think it could get louder without any damage. Please change the volume in mixer_paths.xml on the upper page, change the RX1 Digital Volume, on the lower half page, find section called "earpiece" and change RX1 Digital Volume. Save and reboot.
