How can I disable the noise cancellation mic on CM13? - Xiaomi Redmi 2 Questions & Answers

When I try to record the sound of a band or musical group my redmi 2 didn't record the sound right and in many parties I needed to throw the file away just because the audio is too bad of it and this is caused by the noise cancellation mic. There's a way to me disable it?

What app are you using?

Could it be to do with the Automatic Gain Control?

[Q] Disable noise cancelling mic?

is there a way to do this in the build prop or something? i'm experimenting with teh awful audio in the video camera and i want to see if it's the noise cancelling mic that's really screwing everything up.
i'm also looking to try to change the gain, anyone know how to do that?
I don't have an answer to your question, but have you considered the placement of your hand when recording? It seems to me that it would be easy to muffle the sound by accident.

My guess is if you open the phone app and hit the menu key and then call settings. from there scroll down to noise suppression and uncheck it.
Not sure there is a way to disable it in video though.

yeah, i read that android usually has different ways to use noise cancellation, like the nexus 4 has a diff classification for video and then voice.
also, I put my phone down on a tripod so it's not my hand placement. it's the bad mics in the phone.

Fix-ish
Jishnu made a mod that mods with the mixer path, i have tried it but the noise cancellation mic is still a little bit on. I'm using Xdabbebs camera mod so i hope he will fix this problem, heres the mod: http://forum.xda-developers.com/showthread.php?t=2706943
I've also seen people on youtube recording without the noise cancellation mic but he doesn't show how, https://www.youtube.com/watch?v=1NoxMTxiFvo
If you found a fix, please let me now:good:

did anybody find a solution for this, all my video recordings of my baby are horrible, literally unusable!! :grrr:
I take it it's still not been fixed then, ffs it's absolute ****, I'm sure the Mic software it's geared up for 3 mics and LG haven't realised the 802 only had 2

I wouldn't even try to guess until you provide a reasonable amount of information about your situation. How do you expect us to narrow anything down without any clues?
Where is a sample video clip or even a decent description of the hiss? Tell us under what conditions this occurs, e.g. only on quiet environments, randomly, always, etc. Does it change when you change video quality settings, internal, external mike? What model phone, firmware version and anything else that appears even remotely relevant.
.
oki. ill upload a sample. it occurs under all circumstances, phone is pure stock so camera app and all is out of the box

That seems to be a musical selection.. so how to tell what is part of the unknown music track and what is hiss? Better would have been recording the quietest environment you could find. Or if the hiss only shows up when recording something, then play a recorded music track. And provide both the phone recording and the original music track so that it can be, more or less, subtracted or distinguished from the hiss.
It would help if the track didn't have interfering music or if you tried recording in quiet, moderate, loud environments, impulse sounds, etc with comments on whether the hiss varies under various conditions. At a guess it's the aggressive ALC (auto level control) when you record with the internal (?) mike. So when there is a quiet part in the music, the ALC cranks up the gain and the noise from the phone circuit becomes more apparent. On that theory it would be good to know if using an external mike alleviates the problem or not.
If it is an ALC problem.. there isn't much that you can do about it.. other than consider using an external mike.. not recording in quiet locations, which could be difficult.. or hope that someone disassembles and tames the ALC.

I have the same problem. Even returned my phone to the service and they did smth to the mic, maybe even replaced it. But my problem is still there. Search for check out 'hissing 001' video on youtube, i have uploaded a sampleml. they said they tried recording videos with two other samsung fives, and they all had hissing problems. But i just cant accept that a quality phone like thos has an amateur error like this... for others, sound recording sounds just fine. What can I do?
I'm having the same problem. Not sure when it started but now the hissing sound happens most of the time when I recorded videos. Recording voice through an app doesn't create any hissing sound. Anyone can provide anything we can try? TIA.

I just got my device back from service, and I have to say they did something to it, because now the mic works PERFECT, without hissing whatsoever.
IT could be sw related problem, but i strongly believe they gave me a brand new mic.
good luck!

Thanks for the update Darkerr9. I'm tempted to replace the mic by myself but not so confident I can handle it. Watched how to do it on youtube and will cost me around $25 for the parts. I still think it's software related issue since when recording just voice, it works perfectly. No white noise or anything. ... hmmm.. what to do..?

Ah, I see. Well I still had my warranty so they did it for free. And remember, the 1st time they (another service) tried to fix this, they failed to do so. I guess I got lucky now... voice recording quality is poorer, so that doesnt count imo btw if you use your headset mic, you will see (hear) that the problem is fixed..
Hi everyone. I have the same problem and it's very frustrating. I don't have a solution BUT I know the reason why it's hissing . It's not the microphone! When I record only audio with both microphones it's all OK. The problem occurs when front cam is on! When my girlfriend close up the phone to her ear she heard that awful sound (hissing). So the camera make that noise. Top mic is very close to the cam so mic gets that noise. Try to hear very closely to the cam and check if you have the same noise from cam.

How to boost the speaker volume with mixer path edit

Been looking to boost the loundspeaker such as it is found some guides about editting lines in mixer_path.xml, only thing is my file does not have the values that the guides have which is why I asking the question, anybody know how to boost the volume of the loudspeaker ? I know the risks about blowing the speaker so did not want to just add the lines that I found, any advice or an app that is known to boost the loudspeaker ? Thanks in advance
Nobody knows? Or is everyone happy with the loudspeaker volume?
Have tried a few volume boost apps but they don't cut the mustard
I know you can use Kodi for video and audio files and it has an option to boost volume. You can even get a youtube plugin for those of you like. As for app and games no idea.

Hi, if I may, the answer to a louder sound from built-in speaker, as my colleagues have posted can be achieved by Volume Booster, from omega Centauri, a gemini from an reader app they make. Note that to avoid damage it only boost mid frequencies, avoiding bass and high treble. The quality lowers. So, kernels like Perseus, Devil, Shift, I could name the majority, have customized the approach with algorithms that have names like Boeffla, Faux and many others important, that are drivers lile ALSA for Linux or kernel mode WDM for W. And now try a Note 2 N 7100/7105 with and without Boeffla and all will become clear, specially the effort of developers that we admire. Congrats. :fingers-crossed: sorry for the bad english included.
Thanks all for the suggestions,none of them give me a boost that makes it louder through the speaker, , I also forgot that you can boost the system volume with Viper4Android(which boosts the speaker volume fine on my other device a oneplusone), this also does not work on the Nexus 7,I will have to just live with the low speaker volume as I cannot get it any louder

[GUIDE] Fix front speaker distortion in Pixel 2 XL (no root)

Hello my friends!!
I actually found a way to fix front speaker distortion without root.
1) Disable Google's MusixFx App (com.android.musicfx)
2) Install an equalizer app (In my case i used Equalizer FX. Pro Free version)
3) Open the app (if you haven't disabled yet Google's MusicFx app, it will told you to do so)
4) Depending on how is affected your speaker because the bad mounting (Google's fault) you will have to play lowering the frequencies. In my case I only needed to lower 910Hz to -7db
5) No more distortion!!!....
The only down side it's that you will get a less louder speaker, but 100% enjoyable sound!
I had to return 4 devices until I decided to find a way to "fix it" without rooting... I think Google was already trying to fix it because MusicFX app was updated in latest February update. Let's see if they officially release a fix. I think I will ask for RMA again anyway...
I will try this! My RMA has the same distortion, especially during a video call. I was debating doing another RMA, but the screen seems good so I am not so pressed to do so. Thanks for the info!

Hello!!... It works... But sometimes the equalizer stops working and I have to uninstall and install again... Maybe someone could find a better Equalizer app.
I did also wrote Google about this... They told me to wait and to be patient ... Because they are working "day by day" to solve this issue... That I will receive a notification when the fix is ready... Let's see... If not I will have to do RMA again...

Keep me posted please! I'm in the same boat, I was debating contacting them, but now I won't as I know I'll get the same canned message. The USB C adapter quality sucks too, I use an AuX cable in my VW and man distortion, no sound, feedback at times unsure if you guys have any issues there too?

I have used the USB C adapter with headphones without problem (for now at least)...
If I receive any message from Google I'll update this post.
This doesn't fix the distortion for calls on speakerphone. Any idea how to achieve that without root?
The only thing I'm doing to keep the distortion at bay is by pushing the speaker grills slightly every now and then with my nails. That seems to be working. Nonetheless, these speaker combination is still better than bottom speakers. I'm enjoying way more content than I used to with my OnePlus 3T. Myy wife's OnePlus 5T speakers are louder, but still this one experiences better for me. I hope Google made them right !! But what can we do, they took a greedy mofo for CEO.

This is the solution please dude try to share it with others that they dont know how to fix it. thanks
works for pixel 3 as well
Thanks for the solution. It works for pixel 3 as well!
the best post I've seen, I had not noticed until I made the change although I notice it even if I disable the google one thanksss (You can also increase the volume from the same application and the result is maintained)
The difference in audio quality is really noticeable.. But doesn't seem to work on apps like youtube (Vanced)... Does this only work for dedicated music apps? Works flawlessly on Spotify but would love it to work at least for YouTube...

Go to settings, search for MusicFX. The app will come up. Click on it and select disable.
My sound quality dropped massively from one day to the next. Does anyone know if this has been an issue on the 3XL lately?
I wanted to try this did but I couldn't find the MusicFX app.
