[Q] Audio recording Tweaks ? - LG Optimus 2x

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 ???

Two questions: low battery warning, and mono audio in 720p video recording.

So, I have two quick questions that i hoped i can get some answers for :]
1. You know the low battery warning message that doesnt allow you to use your camera/music player etc when your battery is below a certain percentage? well i was wondering of there was setting or a hack to remove it.
2. The audio quality when recording hd video is really low. not only is it mono, but its like 63kb with a really low sampling rate. If i recall, i remember the omnia hd had terrible audio quality at first, but it was fixed in a later firmware. Will this ever be fixed on the galaxy s/captivate, or has it already been fixed?

[Q] Sense camera vs. Google Play camera: audio/video concerns

Hello! One of the One's biggest selling points for me was the quality of audio/video it has been shown to capture, even at very loud concerts. I go to concerts whenever I have the time, and only lately decided to try recording some video with the phone. What I got (link below) was just a mess.
However, I'm running the Google Play edition ROM, which nukes the stock Sense camera software in favor of the stock Android 4.3 camera app. I was wondering if anyone could offer some insight. Could I expect the same poor level of audio and video quality with the stock Sense camera? There's no seemingly-soundboard quality audio depth, just tons of clipping (i.e. 4:00 - 4:15). There's no bass, either (bass drum starting at 4:23). Also, the auto-focus is on the fritz the entire time due to low lighting, with no way to lock it in the GPe ROM.
Please ignore the first two minutes or so (just skip to 4:00.) I must've been grazing/covering one of the mics. One thing I will give this phone credit for is its OIS -- I was being bopped around by the crowd for a majority of this video, and it is amazingly still for the most part.

How's the GPE ROM working out for you? I'm on the stock ROM and no distortion, but looking to switch to the GPE ROM

The low gain / sensitivity of the secondary microphone

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.....

Problems recording in loud places

Does anybody have this issue when recording a video in say a concert, night club or even your car with loud music on.. the video will playback fine.. however the audio will be really distorted and you can literally hear nothing but fuzz and base.
The Huawei p9 plus has been my first android phone from Apple in the last 4 years, and really like everything about it.. would be a shame if this was an issue that could not be resolved, i had read somewhere online it's due to the huawei having 2 microphones ...
Any help is appreciated
I'm sorry to disappoint you. While my Note 4 made pretty decent video recordings (sound wise) my P9+ is horrible and absolutely useless for recording live music. I haven't found a solution yet other than moving away from the music...about half a mile
My P9plus VIE L09 records audio WONDERFULLY ! It's almost on par with Nokia 808 Pureview, which is fantastic. Audio is recorded undistorted even if you put the smartphone against high levels of sound (close to a loudspeaker for example). I tested and it is really great.
Strange, very strange. I stopped using my P9+ in loud places because of the terrible audio quality. I had my device send in to a Huawei service center. They returned it saying nothing was wrong.
I added a file to demonstrate the distortion in a loud place. It's a zipped mp4 file.
P9plus recording @ over 100 dB
I put the phone at 10 cm in front of one loud (over 100 dB) loudspeaker(Studio monitor JBL LSR 4326) with top microphone to the tweeter and bottom to the woofer, centered in the middle on axis. I could easily go higher in level but already hurt my ears next to the speaker, it was very loud. There is absolutely no distortion. Recorded with stock Huawei's recorder (.mp4 16 bit 48KHz). Sound recorded on camera videos are the same (very clear, detailed and no, no distortion).
Phone stock firmware, VIE L09.

it is like a studio recording )
i will try live record thursday in studio (with my band) and upload here.
Yes, very good mics in P9plus. That song was a compressed mp3 and speakers yelling loud but recording is good and not distorted. You can use your smartphone for interviews for example with very good results. Outdoor it picks up wind but as a trick you can wrap the smartphone in one microfiber cloth and, voila, wind removal (only for audio, not video)
@raduverdes, sound distortion in concerts is very often related to bass levels. Your track contains almost no low-mid and bass, it's mid's an high's and that's probably the reason why it sounds good. In the EW&F track is a lot of bass and combined with the high volume the recordings on my p9+ sound very bad.
@Ce Your (very very short) sample recording is very saturated and distorted. I compared Huawei p9 plus mics with Nokia 808 Pureview (with it's Nokia rich recording technology, supporting sound pressure up to 140 dB according to Nokia) and Huawei keeps up very well against my 808 Pureview, almost as good. Nokia 808 is probably(i'd say, surely) the best audio recorder in the smartphone world so I'm very happy with output quality of Huawei P9 plus. Huawei supports very high levels of pressure without breaking a sweat, similarly to Nokia 808. Recordings are very clean and clear for a mobile phone.
I highly recommend you don't stay in very very very loud places if you want to keep your hearing. Don't listen to music (speakers /headphones) over 80-85 dB for long periods of time. I earn my living with my ears and probably the last thing I want is to go deaf.
You probably don't get better sound recording from a smartphone at the moment, it's way better than iPhone 6s, Samsung S7, LG G5, Xiaomi or whatever flagship smartphone, I listen to lots of audio samples on YouTube before purchasing my P9plus.
Sample recording P9plus @ Grado SR80e & Samsung Tab S 10.5
Here is a sample recording using Grado headphones feed by Samsung tablet (no amp but at max volume) ; stock recorder app, mp4, 128kbps, 48KHz. A little too much mids and highs, I know but you get the image. I think it's very good for a smartphone.
At 1:40 I received a message on my tablet
I made a video test recording at INSANE level (I think over 120 dB) very close to the speaker and yes, it's awful, distorted. I don't want to be in such loud place for sure. At 1-1,5 meters away (~105-110 dB sound level) recording is good, undistorted . So, I'd say Huawei P9plus is wonderful /good in normal to LOUD places and bad/unusable in INSANE, STUPID LOUD places. It's smart enough not recording stupid things.
Hi!
I'm very interested in this thread. I'm just trying to find a successor for my HTC M8, years ago the only android phone that could handle loud sound recordings.
I found this video of Huawei p9 (one of my favorites), and I really impressed about the quality (powerful bass by FunktionOne speakers)
https://www.youtube.com/watch?v=7hAiQplKXls
BUT, reading your comments I'm not sure if this video is true, especially after watching this video of one of you. It's horrible!!!!!
https://forum.xda-developers.com/showpost.php?p=69942999&postcount=4
Maybe some software update??? If someone can confirm that the quality of the first video it's true, tomorrow I'll buy the P9 :laugh:
Thanks!!!

Distorted sound when recording in loud environment

Anyone facing this issue on this device? As stated in the title, it gets distorted when the sound recorded is very loud. Used to work well on my LG G4 and Xperia Z though. Even in normal condition, the quality of the sound recorded is not very good too compared to my previous phones but is considered bearable. After some research, I found that this problem is called audio clipping and already existed since the OPO. I wonder if there is any fix to be done in software like editing the mixer_paths.xml.
Edit: Tried HI-Q MP3 Recorder with raw audio selected in mic selection which means there will be no processing at all (no noise cancellation) and it sounds good surprisingly so is there any way to completely disable this noise cancellation thingy?
I've got the same issue. Recording via OP Camera app, a lot of distortion is in the audio, along with Snapchat too. Using the stock Recording app shows crystal clear audio.

Exactly, noticed this issue when recording high volume audio with snapchat.

Cool, tried the app and the raw mode as suggested. The recording quality is so much better, unbelievable.
It would be great if we could set such a raw mode as default for all recordings (incl. the stock Camera).
Perhaps there is a wise developer around who could help out? Just dreaming...
Man I thought I was the only one dealing with this because I have yet to find a fix for it. However for me it only happens on AOSP/LIneage based ROMS. When I'm on Oxygen OS or Oxygen based ROMS like Freedom OS recording works just fine. It seems to be connected to "Ok Google" functionality because that also stops working for me too on custom ROMS. Ironically it will trigger it initially for me to train my voice model but once I do it stops responding.
Good camera app to use.
I also experienced distortion when trying to record video at a concert. I found an app in the play store called Open Camera. It has an option to record audio unprocessed. I haven't tried it yet in a concert setting but maybe someone will see this and try it. Since many are saying recording with raw audio fixed the distortion issues.
