Hello,
Is there any way to change microphone sentivity, to get less noise in outdoor shooting?
thank you
I have a question regarding all the (useful) camera/video tweaks that appeared not long ago.... I think the audio section, except the quality of its encoding ha been a little left apart.... Do you think there's a way to calibrate or make the microphones auto-calibrate themselves in noisy environments ?
I went to numerous gigs lately but the sensitivity of the microphone is wau too high to get an audible rendition of the shows.... Could this be added or tweaked as well ???
Although the Nexus 6 has 3 microphones (one built in the bottom speaker hole, one on the back plate close to the Micro USB port, and one next to the back camera lens), it looks like audio is always recorded as mono when shooting video. Furthermore, the audio is always captured from the front mic in the speaker hole, which means that it takes the sound from the opposite side of the camera lens.
I've also tried with other camera apps (such as Cinema FV-5 which allows to select between mono and stereo audio) but the audio is recorded mono anyway.
I've then checked the file media_profiles.xml in /system/etc/ and found out that basically all different resolutions had channels="1" , which means that only one (mono) audio channel is recorded.
I've tried to change channels="2" and rebooted but still all audio was recorder as mono and from from the from mic instead of the rear mics.
Any ideas on how to get stereo audio recording?

First of all, I do not have access to a Nexus 6, but I recently made a stereo recording mod available as part of my "larger" Nexus 5 camcorder audio fix over in the Nexus 5 General section.
On hammerhead, the spatial aspect of the stereo recording is surprisingly impressive (although one channel suffers from some "coupled noise").
It helps a lot that the two microphones seem to be of the same make and model (according to the LG service manual). It is also advantageous that the two microphones are symmetrically
placed on the sides of the phone, where scattering and diffraction effects help with spatial separation.
To me it is not clear whether the same level of spatial effect can be achieved with the Nexus 6, but it is worth a try.
I took a quick look at the mixer_paths.xml file where additional edits to enable stereo recording would be required. I can probably help you in getting some form of dual-microphone
recording to work, but there is likely some back-and-forth testing and manual system file editing required. Shoot me a PM if you are interested in pursuing this.
@chdloc has found the solution to this (thanks!)
Here's the thread on how to enable stereo audio recording:

The secondary microphone at the top of the phone seems to be considerably less sensitive as compared to the one at the bottom. I noticed it while doing voice recording in standard and stereo modes.
Just wondering if it's a built in feature by default or something is wrong with my phone.....
Any help / suggestions in this regard shall be appreciated.....
Hello, I have big problem with recording video with external Mic.
I had a lavalier type Mic that I got from Sound Professionals website last year. It worked great with the v30 but on v40 sounds very strange. I mostly record myself playing my instrument (double bass) for study and pedagogic purposes and now low notes sound tubby as if underwater effect...tried lowering sensitivity (gain) but didn't do much difference
I was using HD audio mode on manual video camera
Recording with the internal phone mics is very good but lacks low frequency range (at least until 40hz) so I need external Mic to properly judge my sound production.
I'm seriously considering returning this unless I can connect an external Mic.that has good sound I'm hoping it's just the Mic went bad
Anyone with some external Mic experience please share your experience.
So after some troubleshooting it seems it's the video camera app that has a bug when recording audio from external Mic.
I used the same microphones with the HD audio recorder app and the sound quality is just perfect.
Only when using the video camera app (manual or auto mode) the external microphone sounds like crap.
I used some third party video recording apps and again the external microphones work very well (though these apps don't have all the nice manual audio and video settings as lg's stock app)
Anyone else has a similar experience?
Not sure whether to reset the phone or exchange it...high quality audio video recording is THE reason I buy this phone...
