I have no idea why, but suddenly I have noticed that my Moto G will now record in stereo using the "Titanium Recorder" (TR) app. The settings I am using are 48kHz sample rate, 128 Kbps MP3 Stereo, which may be the format that the phone uses to record audio for video clips.
When I last tested the Moto G's capabilities, it seemed only the camera's video sound track could be recorded in stereo; all other apps I tried (6+) could only record in mono, regardless of the settings.
A previous strange experience involved the use of the ASR recorder, where the default settings (66 Kbps Ogg Stereo) allowed me to record one file in stereo. After changing settings in ASR, subsequent files all came out in mono regardless of settings (can't imagine why).
Anyway, I have rebooted the phone since, and TR still is able to record in stereo. However, I am afraid to change any TR settings for fear of the same thing happening with TR as did with ASR.
Fortunately, given the hardware (limitations of mics, etc.), being able to record in 128 Kbps Stereo MP3 is acceptable to me; recording my piano playing came out pretty well, with no noticeable Automatic Gain Control distortions.
Don't know if this has anything to do with the KK 4.4.3 update; it's certainly not mentioned anywhere by Motorola.

I recently upgraded from a Nokia N95 to a Touch HD. I've been trying to get my Sony DRBT21 bluetooth headphones to work with the touch HD. The phone pairs with the headphones, but the sound quality is poor with no bass and sounds crackly.
Additionally when I turn off/on the headphones, only the headset and microphone profiles connect back to the phone, not the A2DP stereo part. The only way I've found to get it to reconnect is to repair them.
Any idea if this is a known issue with A2DP headphones on the Touch HD? I'm not expecting to get brilliant audio quality, but as it is right now with crackles and distortion it isn't worth listening to.
Just wondering if anyone has any ideas on how I can fix or optimise this?
Cheers
Was the device properly paired? Were you prompted for the PIN? If not, do so manually by going to Bluetooth settings and pair the headset from there.
As for the A2DP not being available when reconnecting, this seems to be a known issue as I experience this intermittently with HTC's own Bluetooth and another third-party one, too. This issue was also observed on my previous HTC Polaris! A workaround for this issue for me is to power off Bluetooth and then power it back on: not a good solution!
It prompted for the PIN which I entered, and looks to be set up correctly. The main issue seems to be the background static when listening to music (hissing and crackling). Is there anything in Advanced config that could be tinkered with to try and alleviate the problem?
This won´t help you:
My Motorola S9 and HT820 (Both A2DP/AVRCP) working fine with HD and Diamond. Also I had some difficulties reconnecting the first times, due to the not used pairing-PIN. The motos doesn´t need it. The HD and the diamond needed some time to accept this
Now they reconnect as Hedset and Stereoheadphons.
Maybe there is another BT-Master (your old phone) active that occupies the A2DP connection with your headset.
I have one HD and S9, sometimes it's a little hard for them to connect but the sound can be very good, the only problem is that with high BitPool values above 30 (medium quality) it's very easy to break the sound when the HD is in our pockets and we are outside the house.
hi, im using the same headphone with you. you got that cracking noise with no bass because it's playing via the headset function, not as stereo headphone.
try disable the heatset option in the bluetooth, then open your music player and try again.
And yes, when u turn off your headset improperly. i.e. turn off from the power button, and not through bluetooth -> disconnect, then turn off... you will have to go to setting -> set as stereo headphone...
I had a play around with Advanced config and found that if I change the max bitpool from 30 to 50, the crackling and static disappears. It seems better now. Many thanks!
Edit: Changed to Max Bitpool 80 and Min 65 and the quality is brilliant. Found some further information from a post on another site (PPCSG) which may be useful to any with a similar issue:
Using ACT (Advance Config Tool), go to BLUETOOTH:
*below are my settings->
-Use Joint Stereo: Yes (default)
-Bitpool: Very High
-Max supported bitpool: 80
-Min support bitpool: 65
-Sample rate: 48000Hz
*My settings may not be the best, therefore you may want to trial and error.
The following shows the named values for the A2DP\Settings key.
By default, A2DP uses a bitpool of 48. A lower bitpool value improves system performance. Increasing bitpool to a higher value causes an overhead on Bluetooth and system resources.
Microsoft suggests the following bitpool values for optimal buffer sizes.
30 - Low audio quality
40 - Medium audio quality
48 - High audio quality
58 - Excellent audio quality
-The maximum reported bit pool value, which can be negotiated with the peer device. Default value is 80.
-The minimum reported bit pool value, which can be negotiated with the peer device. Default value is 14.
-SBC sample rate to use. Default value is 44.1 KHz.
least of your worries...
what bothers Me more is that the old A2DP bug from the HTC Diamond has made its way to the HD ROM, in that if you listen to music via A2DP and recieve a phone call, you take that call and end that call then your music continues playing through the phone speakers! You have no idea how embarassing this is on a train!
that doesnt happen on mine, go straight back to my headphone again...
Even though it doesnt happen on mine, to be safe I plug a dummy headphone jact to the phone so even if bt gets disconnected, no sound goes through decice speakers. Makes me feel comfortable on the train. This was also an issue with Cruise which was addressed by a hotfix later on.

Tried that, and the difference is staggering!
I can now confirm that it isn't a hardware issue, that these phones (Sony HBH-IS800) are capable of sound quality just as good as other Sony in-ear jobs. Thanks for that!
Now, all I have to do is try to sort out the drop-outs. It seems as though the slightest barrier can cause drop-outs, for instance, putting the phone in my jacket pocket, or passing my jacket sleeve in front of it. Not sure whether it's the particular material of my jacket, or the metal in the buttons, or what, but it's hugely irritating.
Funnily enough, seems to make a difference if I have the connecting wire behind or in front of my neck. More to follow on this one....
Cheers

noise ?
For people using the HD and motorola S705 as bluetooth A2DP : do you have also an annoying background noise when listening to quiet music ? Or before the sound starts. You know a noise like pffffffffffffffffffffff
HTC P3600
Hello,
I already installed the tornado_a2dp.cab on my PDA HTC P3600 with WM5. but I can't sincronize MP3 (Windows Media Player or TCPMP) with my headphones Nokia BH-206.
Anybody help me to solve this problem?
The mp3 sound only worked (10seconds) in Windows Media Player when I press the button to do a call
Hi.
I have done the changes mentioned in this thread and got much better sound when listening to music.
But i still have a static noise when im in a call.
Is there a way to fix this?

I am having the same problem as you on my HTC Incredible. Any idea of an app that lets you configure those settings for Android?
Heyho,
I noticed a really annoying problem the other day when I was watching an episode of The Mentalist on the bus.
First of all a list of what I used when the problem occured
- X1i flashed with Itje's Touch-IT Xperience 3.01.
- Sony Ericsson HBH-IS800 Bluetooth headset
- A 230mb 45-minute 800x480 h.264 video file, packed in an mp4 at 500kb/s.
The problem that occured is that when my bluetooth headset was connected (and playing the audio), the video would lag like hell, e.g. 1 fps or less.
When I disconnected the bluetooth headset and used my wired 3.5mm jack headset, there was not a problem at all!
How do I fix this!?
the same thing happens when i use my hbh-ds980 for watching videos..
what i did to resolve this issue was to use the Super video convertor by eRightSoft (freeware) and convert my videos to MP4 with the "Hi Quality" and "Top Quality" boxes checked in the Video options. so even if i convert videos at 23 fps at 800x480 resolution, video and audio play smoothly through A2DP.
Happens to me too, I use the Motorola SoundPilot S705 and with bluetooth headsets the video lags, while with wired headset quite smooth.
I watch Divx video encoded for PC playback with coreplayer...
update:
Does this has anything to do with the issue? the bluetooth audio bitpool:

i will try tonight when i get home.
I will test those advanced config settings and see what it does.
Sounds fine now, but doesn't fix my problem. Who can tell me more?

What is "Fine" now? better sound? did you reduce o increase the bitpool?
I increased the bitpool and I feel the sound is better, less crackly. Still, it's not the answer to my prying question.
Hallo,
I have the same problem after download norti roms nX1i v1.03 and 1.03 Did you solve it?

Nope, haven't found a fix yet. It's still too slow. Nobody had an answer..
did you ever figure this out?
i just bought a bluetooth headset (jabra bt3030) and i thought id give it a try with my x1a running the orignal rom, software version r1aa021 / customization version R2A.
As for my experience, i dont have any video lag using dvd movies converted at 640x320 768kbps/64 kbps audio and other videos converted at 480 x 320 500kbps/64 kpbs audio. movies were converted using super and also nero recode 2 and played using the media player and also the panel media player.
the only problem i have encountered once in while when starting a movie is the audio would be out of sync. the remedy that i found out for this is to pause the video and then push play again, then everything audio and video is synched up. i think it has more to do with the bluetooth, phone or headset, i dont know which but i figure this because when i start my movie, the movie starts before my bluetooth headset would like click on and start to play the audio.
i see you are using a customized rom, do you think that could be part of the problem? too high of a resolution? i didnt notice much of resolution difference between video converted at 800 x 400 and 640 x 320, 480 x ??? at the same kpbs. then again im not a big hd buff and my eyes arent as sharp as others. the smaller resolution played just as well in full screen mode. i think nero recode 2 does a pretty good job at converting videos, a lot quicker than using super and i got nero free with the cheap dvd writer i bought.
hope you got it figured out but if not, hope this helps others.
im using Nokia BH-503 stereoheadset im not having problems regarding to bluetooth and lags.
im using windows media player and of course i convert the video files to smaller resolution like 480x260.
also tried playing 800x600 but acceptable lags like every 15mins lags for lessthan 1 secs with bluetooth headset.
also try to end background task in your phone like antivirus, skype, etc... it might affect the performance of your phone.
U can use Core Player and there is an option to adjust the time synchronization between video and audio.
I've had these problems whilst playing x264 encoded files. I think that they just suck too much CPU power. It's not that the video and audio desynced or anything. It just had a really low fps! (like 3~4)
My current phone is a Moto G 2014. The stereo mic and speaker is a really nice thing. Motorola unfortunately changed the G 2015 and X Play to Mono output. Did this happen to mic too? This detail is really seldom mentioned in technical data. For the G 2015 my question was positive answered, but I'm considering to buy the Moto X Play because it is a bit faster, has more memory and seems to support ExFAT (does it?) as memory cards bigger than 32 GB are officially supported.
It's easy to test: To record stereo on the G 2014 you need some app that identifies a camcorder if I understood right. Most apps are not capable to record stereo. It works fine using the Titanium recorder when recording mp3. Or just use the internal camera and record a video. Start Titanium recorder recording mp3 or the default Motorola Camera recording video. Speak "Left" in the left speaker and "right" in the right. Connect headphones and replay the result, carefully listening if the sides can acoustically be recognized and sound fine.
Thank you in advance!

I tested it. Moto X Play definitely has Stereo Mic. Even MX Player shows Stereo Channels at a bit-rate of 128 kbits/sec.
Does anyone have any experience in regard to connecting external microphones to the OP5?
The idea behind this is that I want to record classical music with a high dynamic range without any compression or clippings. I'd like to record myself playing the piano both with an HD video and good audio quality or just use it as an audio-only recording device for concerts etc. In the end I'd like to have a recording that gives me at least uncompressed PCM-audio at 16Bit and 44.1kHz as CD quality stereo tracks.
The microphones in question could either be small binaural microphones or a semi-professional setup with a pair of Neumann U67/87 and I'd like to know whether the OP5 can make native use of those microphones, i.e. using its own Analog-to-Digital converter, or whether it is necessary to directly feed a pre-processed digital signal to the phone via USB.
Any pointers to an existing discussion are welcome, just as much as your personal experience, tips and tricks for this kind of set up.
Hi, I have been looking and looking, and it seems that the default camera app doesn't support external mics, but a 3rd party app does, like open camera, but for me, it zooms in a lot when recording.... it sucks
I can now state that it is possible to use external microphones.
I've bought a microphone pre-amp UR22-MK2 by Behringer that puts out a digital signal via USB an using a USB-To-GO adapter, I can feed this into the OP5. The stock camera automatically detects this external audio source and uses it, deactivating the internal microphones.
Unfortunately there are sometimes audible clicks, which do not occur when I record on a PC from the Behringer input. I suspect it's small hickups due to compressing the audio track while recording into an MP4 container.
I wish there was a video app that lets me define lossless audio recording.
Hi, I'm sorry to bother as I've searched the V20 forum and I'm not finding related info on this problem.
With LG V20 video recorded with HD audio setting on, when I open/import it into Magix (once Sony) Vegas 15 opens with low volume, highly distorted audio. It shows the video but the audio is garbled/distorted, low volume, audio. If I bring in a video file without HD audio turned on I'm able to open it and video and audio playback is fine.
Note: All video are .MP4 files and playback fine on the LG V20 itself (At&t H910) as well as on the desktop with WMP and VLC Player, with HD audio selected or not. I just can't get it to open without issue (audio) in Magix Vegas Pro.
I'm thinking (hoping) it might just be a codec issue and this can somehow be resolved, but even after installing K-lite (mega) I'm having no luck. It only happens with video .MP4 video files with a setting of "HD audio ON". Is there a known V20 issue here in regard?
Can anyone shed some light on how to resolve this?
Desktop OS: Windows 7 Pro x64 SP1
Phone: LG V20 AT&T H910 (Stock, has latest OTA updates)
Not real familiar with Vegas. But you may be right, it sounds very much like a codec issue. So lets try and narrow things down a little. Find out what the audio sample rate, channels and bitrate are on the non-HD files, then do the very same with the "HD" filles. What does Vegas say they are?
I never tried the HD audio before. Because it just sounded like a gimmick. Their "HD" just may be referring towards some higher bitrates.....or.... Because most audio these days are already what you'd call "Hi-Fi". So it's possible these files are in a much higher sample rate. I can't find that info out because nothing on the phone seems to want to give the AUDIO details of a video. ? It's frustrating.
