Mono sound on video HD recording, why?

I don't know why but any video I make with my i9000 has an ac2 mono sound. No matter what resolution I pick for the video. Isn't there a workaround for this? To make it at least stereo if not better?

The phone does not have 2 microphones in the first place. Hence recorded audio is mono.
Video resolution should not be affecting its audio.

Ok but before sgs I owned an iphone and guess what it recorded video with stereo and only one mic. It is software related. Must be...

But do you hear difference in the left and right channel?
If it doesn't, SGS encodes it in a more bandwdth efficient manner.

Then it wasn't stereo. It may have been twin mono. But, as said, why waste space recording twin mono.

As far as I know stereo sounds better as mono, that's why I prefer the more non efficient way of encoding. And let's not talk about having a very good quality video stream beside a poor audio one.

As far as I know stereo means absolutely nothing if the device doesn't have the hardware to capture in stereo. Mono does not necessarily indicate inferior quality. Your iPhone has recorded in mono but just replicated the channels to appear as stereo. Samsung Galaxy S rather honestly reported mono and let the playback device (eg. computer) replicate the channels whenever necessary. The audio quality boils down to the bit rate and sampling rate used; and these should be considered in development of improving SGS's audio recording quality.

the SGS has no option to select the recording level, and bandwidth/bit rate to begin with
so you get what you get.
we are waiting for an App or a Hack to allow uses to change the recording bit rate so it can get better sound

True, so the development has to focus on hacking the bit rate and sampling rate, rather than producing fake stereo.

True but you gotta admit, the video is in hd for christ sake and the sound is not even close to the quality of video...c'mon. A bigger bitrate would be helpfull, at least AC3.

that is what every one is complaining about, including myself
we need an App to control which recording sound frecuency we want to use instead of whatever it's the default, which sounds like something on the 11Hz or 22 Hz at best guestimate

Beats Audio + Network Streaming

I jumped the gun and got my Nexus 7 early. Due to my impatience, I'm left with the limited space my N7 has left. I use Skifta/Doubletwist/iMediashare to listen to my fairly large music collection on my PC and Droid 3, but nothing I can find supports Beats Audio like Google Music.
Is there a way, without using my external SD reader and OTG to listen to my music via WiFi/Bluetooth and still keep the great sound of Beats Audio?

Not be one of those guys, but beats audio is just an eq setting chosen by dre and co that boosts bass scoops some mids and brightens up top.
Dre doesnt know what headphones you use or speaker system you use or the acoustics of the room you're in, so he doesn't know if it is an improvement or not.
Keep eq flatish or EQ until YOU like it on your playback system.
The whole thing is bit of a con, as a studio engineer producer myself it annoys the hell out me!
If u like it that what matters but you can do without it, is my point.
Edit . also Dr dre is in his 40's and a lifelong live performer and producer so his ears are knackered, mainly in the sense that he hears things duller than reality for youngsters. I wouldnt want him setting the eq on my playback. Now he can hear when a tune works of course but 16khz, prob not.

Ditto... my kids keep wanting me to get them the beats headphones and I just laugh and hand them my Sennheisers from the studio and tell them to put some real ones on.

I wouldn't spend money on the headphones, I have a set of my own that are just as nice without the price tag. I just like the Awesome Beats EQ. Its pretty simple and it definitely sounds better than the original DSP Manager.

App for good live music recordings?

The htc voice recorder app distorts with live band sound levels. The video camera records beautiful clear undistorted audio of the same band. It seems htc didn't put the same brains into the voice recorder app... It'd be nice not to have to waste storage on video just to get good live music audio recordings. Anybody know how to fix this? There don't seem to be any gain settings in the app...

You could always record the video, go home and extract the audio with a PC application then delete the video.

thanks for the suggestion, i did end up using the video app to record, then found an app called "Android Audio Editor" that could actually transcode mp3 audio from the mp4 video right on the phone. It's a 3 day trial of the app, but it did a nice job. Here's a sloppy rehearsal of a live recording in a small room with live drums. Pretty impressive for a phone!

I've gotten some decent "live" recordings using the earbud mic filter. Just plug in the beats earbuds and record with the system app.

Interesting, I haven't tried that, I assumed that was a mono Mic. (Maybe better for covert bootlegs?)
I'm really excited about the great stereo dual membrane mics on the One, they sound impressive for music taken from video, we just need to find an audio only app that can take advantage of the great mics correctly.

Irig seems to be decent. If you register you can optimize the audio some.

[Q] Beats audio sound quality question

I'm considering picking up this phone and I've seen quite a few claims that if you disabling Beats will "replace the beats profile with one that reduces audio quality" instead.
Anyone confirm/deny this? If it's true, does it make a large difference? Are there any ways (Custom ROM, kernel, etc..) that fixes this problem?
PLEASE NOTE: I do not want comments on how the beats audio sounds better than anything else - I want comments on if turning it OFF will degrade the sound quality as some people claim.

It sounds better with beats audio but it sounds great with it off as well.

Sounds better is subjective. WHY does it sound better? Explain!
With my taste in music I want a "bright" sound with pretty controlled and laid back bass. I do consider myself quite enthusiastic about good sound quality and honestly, afaik Beats sounds, to me, the entire opposite of what I think is good sound quality.
Anyone can explain to me how the sound quality compares to any other phone they've used?

imho, it seems just making the volume louder, but cannot hear much difference... would anyone advise me if there is some kind of settings/ EQ etc? I can't find that... thanks

AFAIK Beat is an active equaliser, meaning that it adjusts to the audio input so that the output isn't distorted and sounds as good as it can on a software level, sure you can create sound like this with an EQ, but then you may have to create sound profiles for ever genre rather than just playing it, but for the record it creates better sound quality which is consistent with all music types that i've tried it with. (magic )
Bass is stronger, delivering a crisper yet softer bass as opposed to a punchy crackle which you'll find on other handsets, trebles are fair and i've heard much louder but in terms of actual clarity it's right up there with the best, mid levels are decent too, so if you want a treble sounding phone then this isn't for you, but for everything else and for the whole package this is where it's at.
I'm referring to the sound that the phone itself delivers, if you were to couple this with a decent set of headphones (i got a pair of solo beats for free with my phone from carphone warehouse, i think they've sold out now) the sound is phenomenal, for picking up and playing a song it is second to none, not the galaxy s4 nor any of the other top of the range handsets can compare to it, the reason for this is because HTC has obviously done it's homework for the audio part of the system and used it as a major selling point.
I'm by no means a music enthusiast but i love them and several of my friends who are music enthusiasts (some producers and DJ's) have said that the sound is superb, obviously not as good as a studio but lets not forget that this is a phone that we're talking about here and for what it is it won't be beaten.

Yep, thus meaning the sound signature should be rather inconsistent as it changes from song to song, right?

That's exactly what I do not want when using my Sennheiser headphones.
Boosting the bass gives a sound signature I really do not like too much. I want it to be balanced and rather a bit laid back as opposed to strong and, imo, overpowering. Bright and detailed with a wide soundstage is more my cup of tea.

Can I remind you all that my question isn't about how the beats profile sounds like but just if the sound quality does noticeably degrade (even compared to other phones) when you DISABLE it?

Sounds like your already dead set against it, why don't you go down to a shop with your headphones and try it out, sorry but I'm not going to delve Into how I feel about the sound quality anymore, this thread and your responses are about as predantic as it gets. I tried to give you a detailed explanation and my experience of the sound on top of other people whom I know.
You don't appear to want to hear that so get one and try it for yourself.

None of these replies have answered my question about it though. so let me rephase:
I've seen several reviews claim that this phone use 2 different profiles for Beats audio;
1. The ON profile which activates the "enhancement"
2. The OFF profile which, rather than just deactivating beats audio, will reduce the sound quality below that of what the DAC is capable of.
Now may I have any comments relevant to this question (rather than just saying the sound quality of this phone is good or bad).
Also, not all stores here allow you to try out the phones like so unfortunately.
EDIT: Thanks to the LinusTechTips forum I found this video which pretty much explains what I've been saying: www.youtube.com/watch?v=Cdbn_pmxFic

I think it's much clearer, and s bit louder. But clearer. I used to have an HTC sensation, where in the middle of your video or music you had a toggle to turn off Beats. And trust me, there is a difference. I even record university lectures on it, and beats tunes out the background noise and boosts that of the speaker. It does wonders . But you can always get the phone and turn off Beats and download an equalizer from the pay store.

We're missing a critical piece of information from you : do you primarily listen through the phone's speakers or use headphones? Given that you don't seem to have a One yet (and thus have normal phone speakers which are pretty terrible ) you probably use headphones. The reason this is critical (and why the whole situation is kind of irrelevant) is because when using the phone speakers turning the enhancement off does make it sound worse IMO. However, if you're using headphones, turning it off makes it sound better assuming you have a decent pair of course. I don't know if you're like me and prefer a natural base level over an artificially high one, but if you are then you can just turn off beats and let the headphones do the work and it will sound just as good as using any other portable audio player out there. See why it's all irrelevant now? You can turn it on to use it when it's good and off when it's not, and if you personally feel that it's never good, then you can just turn it off and rely only on the hardware which is just as good as any other portable source.
So take home points (I'll keep them simple and clear) :
1. Yes it sounds worse if you turn off beats when using the phone's speakers.
2. It does sound better to those looking for a more natural sound profile to turn off beats when using a pair of quality headphones.
3. Turning off beats does not seem to activate an "intentionally low quality profile." That wouldn't make any sense, it's just a tweaked equalizer...

Thanks for a good and detailed response - This is the kind of reply I was looking for!
Also. good to see an opinion from someone that seemingly have a similar taste in sound signature as I do.
Yep I'm thinking of the headphone performance indeed, speakers I usually don't care too much about, I can see why they seemingly optimized the speakers for use with the beats turned on.
Another thing to mention, I'm coming from the Galaxy Nexus which has a rather decent DAC. Nothing spectacular but decent enough. If you have any comments on the SQ difference between the One and the Gnex or any similar devices, do post them.

Happy to help!
For practicality reasons I too usually use headphones. I'm sorry I've never had a galaxy line phone to compare to. But if you think about it theoretically, you're going to be playing mp3 files in all likelihood. Hopefully they're 320kbps at least, but still mp3s. At this level of listening comparing one source to another is pretty difficult I think; there's just too much compression already. Which is why I think contrasting portable audio source quality is a moot point, it depends more on the headphones. But fortunately you need to get up into the thousands of dollars in equipment to decern the finer details anyway.

Actually most of my collection is ripped in flac ^^
My setup at home is a far better source than any phone can produce, not super high end but still a good setup.
Nonetheless, I care for having a decent enough audio source from my phone as a large portion of my music listening is when away from home and I don't want to carry a ton of portable equipment and media players when I can have it all done from my phone.

Sorry meant galaxy nexus

sound quality and Beats audio not good enough

I had used before HTCHD2 . HTC Mozart 7. HTC Desire HD. HTC sensation XE, HTC one, HTC Droid Dna, now HTC Butterfly S
In my experience the sound quality best ever is Droid DNA, beats audio and deep bass very effective and clear.
i noticed in Butterfly S the bass not deep enough and the beats audio on and off almost same a very little different when turn off and on the beats audio in butterfly s in comparison with Droid DNA, besides when i turn on the X-Wide in jet audio making a little distortion, in Droid Dna no problem and very clear.
Usually am listen to music by connecting the phone in car audio system with amplifier and big sup woofer.
Anybody experience the Droid Dna sound Quality and the butterfly s.?
If any suggestion or solution please inform me.
Thanks

hmm, the DNA's DAC has a bit less dynamic range than the Butterfly s, so it may give a more "harder" sound. According to tests done by GSMArena the Butterfly s has a higher dynamic range and less IMD (a bit more THD though), so theoretically its sound quality should be "better." However, you're used to a more bassy sound you may not like it.
What volume are you listening at? Using the stock music app, volume levels above 11/15 can sound distorted using In-Ear headphones. See this thread http://forum.xda-developers.com/showthread.php?t=2423846
Using third-party players like PowerAMP can fix this at some higher volumes but there is an occasional clicking that occurs (similar to skipping on old Android Phones.)
Maybe give PowerAMP a try because when I used JetAudio on my HTC One X+, some of the enhancements distorted a bit.
If you don't want any clicking, I think stock player is the only one that works as it seems to use a different audio thread. (you can't use any equalizer app with it)
