Sound on video recording - HTC Desire S

Hi there,
I noticed that when I'm recording a video in a noisy place, like a concert hall or something like that, the sound is horrible, you can hardly understand what is going on. Is there a way to solve the problem?

Unlikely. Sound recording is a delicate thing. To produce quality recording, huge directed microphones are used, the sound is recorded at a very high rate, and filters are applied. None of those can be done on a phone.

OK, I understand that, I'm working with sound. But I read somewhere that this is happening due to the ARM codec, which compress the sound at a very low biterate. Can this be changed? Or, at least, lowered the recording volume?

Again, no, because - 1) you're limited by the codec HW implementation, 2) the write speed to SD card is limited, and the less you compress the audio - the more bandwidth it takes.
The recording volume can be lowered, I think. Just not sure how - never tried.

Reducing mic output gain on video record. Why? Cause its too loud & distorts

I'm looking to reduce the mic gain level while recording video. I notice it doesn't take too loud of a noise to cause distortion when you play it back. I also notice it picks up even the tinniest of sounds. Eg... its very sensitive. It picks up a small fan 20 feet away and on the video it sounds like you are standing next to it. In a way, this can be good, but in most ways it's not. What is the exact setting to adjust to ruduce the mic output gain level? I'm sure it's in the Audiopara file, but if someone knows exactly which setting so I wont have to be tweaking 2 or 3 of them to find it, it would be helpful. Thank you guys n gals

[Q] How to improve sound quality during video recording

Is there a way to improve the sound quality during video recording on the Sensation?
When recording loud music in a club or a consert, the quality is realy bad.
I guess the microphone input level is to high.
Is there a working solution for this?

Goto HKCU/Software/Samsung/Camera
Find AudioNormalCodec
the options are:
0 - Default : GSM-AMR-NB 8000Hz 1ch (this is the default but has lots of high pitched noises in the background)
1 - MPEG4 AAC 16000Hz 1ch (this so far is the cleanest audio that I found you can get during video recording)
2 - Qualcomm QCELP 1000Hz 2ch (this is the MMS setting, not good at all for video recording)
I have found this solution, but i can't find "AudioNormalCodec" in my Omnia II...
if you can, pls let me know.

You know that you posted this in HTC Sensation forum? Can you tell me where can I find register on android device?
Hi.
Got the same problem, I tried to make a video during a gig and the sound was horrible, no way to fix that you think ?
Thx.
got the same problem sound qualityis okay but after playin in pc or phone i got some noises during playback zzz zzz sound
Just came back from a concert yesterday and am really dissapointed about the quality of the sound. picture is just amazing but my girlfriends Galaxy S had way better sound recording. anny progress in this?
I'd read in other thread that unchecking the stereo option in video camera settings the sound was better...

not so sure about that to be honest, recorded at a gig last night with latest revolution hd 4.1.4 rom and the sound was horrible
really would appreciate it if someone knows or could find a way to take the recording volume down a notch or two

Surely there must be an app or developer out there who knows how to fix this mess. Again, another event recording ruined. The htc sensation is fine for unamplified natural voices, but even speech or music at LOW volume is pingy, distorted and generally sux.
The Chic Corea concert I recorded was a total disaster. unticking stereo still not effective. Why does iphone make great recordings, but htc can't get it together? or is this an android issue in general? Don't get me wrong... love android and open source, but really... someone needs to nail this one. Is there any point in complaining to htc? ♥

Natural voices are ok, but this makes two concert video recordings ruined using my htc sensation. the sound is distorted pingy and beyond painful to listen to. Can't some brilliant developer create an app or fix for this? Is there any point complaining to htc, or are they too busy getting out their latest phone?
Sux that iphone video recordings. Natural voice and music is ok, but anything amplified, even at a moderate level, is ping-distortion city. and turning off stereo setting doesn't help much either. Thanks for the whine, now the cheese.
done some digging and i think, from what i read, android wasn't given a facility to lower recording volume. so i guess that plus a highly sensitive mic equals crappy sound recording with no fix, for the time being hopefully
I don't think it has to do with Android. I remember at some point on my Vibrant I was able to change the setting and got much better sound after. It may have been a DSP manager app I did it through or it could have been a setting when I was using CM7. Either way, I'm almost positive there is a way to adjust it.
sound quality
I have found a big improvement in sound quality by UN checking stereo sound in the video recorder setting menu.
+1 on this, I'd love to figure this out
I agree. This is one of the weakest points of the sensation. We have great video capture - but the sound can totally ruin the experience. If a Dev could figure this out it would be golden!
I am not sure about this, just a quick thought. But MAYBE the noise comes from the mics on the back of the sensation? Maybe HTC didn't thought about turning off the those mic's while recording.
Just a thought...
I believe the stereo recording uses the 2nd mic above the camera, while mono just uses the standard mic, that we make calls with. I did some tests just by covering the mic holes while recording.
I just think it would be great if we could have a DEV take a look at how to lower the mic gain.
There is a thread over in the HD2 forums, that deals with edits to some lib files for mic gain, but I don't know if that would be something to take a look at. Here is the thread:
http://forum.xda-developers.com/showthread.php?t=1162224
We need this fixed!
I think the problem is that there is no normal codec for audio coding. Oddly Andoid revolution HD writes with a frequency of 44,100 Hz, but the quality is very poor, although an order of magnitude better than in HyperSensation. Unfortunaly, developer chamber is at the bottom, and understandably so - because enough other bugs.
Just wanted to check in on this old thread and see if this is all still in issue with the Sensation and the latest ICS Roms? Wondering if HTC has fixed the high mic gain by now?
Thanks

Stereo Audio Recording?

Can any of the early adopters here confirm whether the Pixel (not XL) is capable of recording stereo audio when capturing videos? All of the example videos I've seen on YouTube seem to be recorded with monaural audio.
This could be the only deal breaker for me. I take my HTC M8 to concerts frequently, and it captures phenomenal stereo audio that doesn't distort or clip in loud venues. As much as I like the Pixel, I would probably have to buy the HTC 10 instead if the audio recording capabilities were overlooked by Google.

I just did some testing for you. The built in video recorder records in mono. However, the Pixel obviously has the ability to record in stereo because I just tried the "Sony Audio recorder" on Google Play and it records stereo audio. If you just need audio and not video this has the ability to record very high quality stereo recordings.

Wow thanks for looking into this!
I'm really disappointed to learn that the "best phone camera ever" doesn't record videos in stereo! Google really needs to address this in an app update quickly.
Good to know that the hardware is capable, at least. The Pixel also seems to do well in very high sound pressure levels too, based on concert clips I've seen posted on Youtube (this is something HTC has always excelled at).

Okay.... It is not very meaningful as "stereo" it is not an XY or A-B studio recording physical pattern.
It is more useful for most people as a mono recording, less noise that is heavy left or right from handling phone to record a "home video" (of a meowing cat or cute baby etc)
That said I am an audio engineer and musician, and I can see a usefulness in having two sources, in case one is better. Mixing them might be better with some of each side panned to the other.
I just consider it two channel recording. Stereo is about perceiving a binaural field L+R, not just two paired signals. The analogy isn't moot. A single mic close to a sound source in a studio and one mic in a distant point that provides "room noise" or "reverb" is 2 channels, not a stereo.
So I think it better to know that there are many options and considerations to make when you do use an app to record with both mics as to how to mix the sources knowing they aren't intrinsically just stereo. That's why I prefer the built in camera app to just stick to mono which is overall better sound for most people. 2 channels only sound good if you do some "audio mixing" in a DAW....

In your tests, did you compare the waveform of both channels to see if differences exist? How do you know the Sony app didn't just take the mono input and record it to both left and right channels?
Hi I didn't compare the waveforms I just listened to the audio. If you record a single sound source and rotate the phone while recording you can hear the sound going from one ear to the other on playback. If it was a mono recording you wouldn't be able to tell that the phone was being rotated at the time the recording was made.
So which mic is left, and which one is right?

You can easily tell immediately if a video was recorded with 1 or 2 channels of audio, especially when wearing headphones. Here is a clip I recorded with my HTC M8... Notice how the sound pans when I turn the camera away from the stage!
https://youtu.be/-yqL9uD2oxY
2 channels is simply more lifelike... We have two ears, so the Pixel should be using two mics for the most realistic audio.
Device: Pixel (sailfish) running Android 7.1 Nougat
One of our users (we are developers of an audio recorder app on Google Play) is reporting that the top microphone on the Pixel has a slight hiss (when he records stereo audio).
Is this an exception (maybe just a bad device) ? Or are other Pixel users seeing this as a general behavior on Pixels ?
This is confirmed when he records mono audio as well, by using the top microphone (aka "Camcorder" microphone). In our app, the user can choose the "Audio Source for Mono" and set it to Camcorder for the top microphone. For stereo, the user can modify the "Audio Source for Stereo" to find a setting that works best. Even the best setting there had a hiss when recording audio. Hiss was less obvious in certain environments.
Hiss in the top microphone on Android phones can be due to interference from the antenna. One can test if this is the cause, by turning on the Airplane Mode (which shuts off the antenna). Usually the hiss will disappear.
However, in his case the top microphone persisted in having that slight hiss (even with Airplane Mode set to On).
Thanks.
EDIT:
To test this with our app, you can search "mp3 recorder" on Google Play - our app is the "Amazing MP3 Recorder Pro" app there.
EDIT 2:
I have heard back from one person who is suggesting the problem is NOT universal to Pixel - and may just be a problem with that user's device (thus warranting a RMA - Return Merchandise authorization i.e. a return candidate).

Poor, low quality audio during video recordings

When recording videos, audio volume is low, and the quality seems way off, almost like there's a slight robotic effect, or as though the audio track's bitrate is lower than it should be.
To add to the oddness, there will often be a tenth-of-a-second (give or take) at the beginning OR end of the video that's at normal volume and quality...
As far as I can tell, nothing's covering any of the mics. I'm currently running the latest Nougat beta, but the same thing happened on 6.0.1. Maybe a clean install is necessary? I don't even have a lot installed.
Here's a [bad] video sample, originally recorded with Skype as a video message but later saved:
https://youtu.be/sjHlc_ShOrU
You can hear the bad audio at the beginning. It also lacks additional bass. Quality gets a little better through the rest, but you can hear the brief portion at the end where volume is where it should be.

Question Sound dies down when the bass drops.

When playing songs at full volume with outdoor mode on at full volumes the vocals die down when the bass hits, it sounds like a cheap Bluetooth speaker. Anyone else facing the same issue?
Please try it and let me know if the vocals get dim when the base hits.
Try the Song Glass House by MGK or any of the drake songs.
Thank you
Your sure it's not a sound system issue?
If the device performs well with quality headphones it's likely not the cause.
You should be coming out in the 24bit digital realm if possible otherwise it will degrade the sound quality if the source is high fidelity.
Hi.
So I noticed this issue early on and I tried the song you mentioned and have replicated the problem.
Except, I don't think it's a bug. In outdoor mode, the volume is boosted but at that volume the bass would be distorting in these speakers and therefore it lowers the overall sound.
You can replicate this even without outdoor mode on but with bass slider at max in audiowizard. You will get the same problem.
So, it works this way because that's how it's designed. Unfortunately.

Alright thank you, but that's the thing I mean the speakers are good but you cannot use them to their full potential, the front camera is absolutely terrible for video calls, Snapchat is just a blurred face, I mean what's the point of this phone when it cannot get the basics right it overheats but 40C is acceptable. But thank you for confirming, I thought there is some hardware issue with my phone.
I think that's just the audio processing trying to compensate for the bass and prevent speaker over-excursion with soft clipping or dynamic range compression. The speakers are inherently limited in size and as far as I know, the phone doesn't use the entire back or front to improve bass response (like LG's Boombox feature).
You can try to EQ the bass down or disable the DTS processing.

Use Poweramp for complete equalizer control.
It's limiter works flawlessly.
If the phone 24 bit digital output and you use it there should be no issues on the phone side.
