Changing audio codec in video recording
Video recoding with camera app uses for audio this codec: AMR-NB 4.75-2.2kbps sampled @ 8kHz
Is there any way to change it to something less ****ty like AAC?
It is a OS limitation or app limitation?
Really...what is with the telephone quality 8Khz audio quality when recording video with the N1?
I noticed this immediately after switching from the iPhone to the N1 ... and it bothers me immensely
There must be some sort of fix for this...surely the quality of the microphone can't be THAT bad
I agree. maybe it will be fixed with a firmware update. I also don't like the somewhat low 20 frames per second video recording either.
yea... this phone phone has better optics and hardware than the current iPhone 3GS, we should be seeing some really good definition video and sound here. this also bugs me, as i came from a 3gs like yourself.
if you check out RTA Analyzer from the market and run a white noise test on it, you'll see the microphone is lacking severely...
+1 Its horrible

But we got two mics on the phone it have to be better, cant anyone fix this?!
My research shows this is a hardware limitation on the N1 - the actual A/D convertor only works at 8kHz according to Google's official spec-
http://www.google.com/phone/static/en_US-nexusone_tech_specs.html
"AMR-NB 4.75 to 12.2 kbps sampled @ 8 kHz" is the only listed encoder, I presume this is on-chip so can't be changed.
I too am very disappointed with this audio encoder (only other thing I dislike is the mediocre axis-swapping touchscreen on the N1 - but that's only really bad for games)
after it is possible to ramp the video up to 720p i think it should also be possible to ramp up the audio, any developers have thoughts on this?

you should download a voice memo app for the Nexus One, there the audio doesn;t sound half as bad, higher bitrates are also possible!

Hi Diamond users,
CorePlayer Mobile 1.2.5 runs practically fine on the Diamond, using the Qualcomm TV graphics chip (QTv) in "TyTN II driver mode" (smooth zoom on and quality high).
Thing is that CorePlayer only performs good with video files with a not too high quality, so a quite low resolution and bitrate.
Only then you can have a good framerate.
Videos with a higher resolution, e.g. 640 x 480, the same as the display's resolution and a bitrate like 1200 kbps for MPEG4 video plays well, but the QTv chip has trouble keeping up the framerate, resulting in some small, but noticeable stuttering, especially when the 'camera moves' in videos.
Any tips on that, or do I just demand too much here.
Second: CorePlayer and A2DP.
When I have my Bluetooth A2DP headset on, CorePlayer (and/or the Diamond) starts to drop lots of frames, even on the lower quality movies that have a proper framerate when not using A2DP.
Is A2DP demanding that much resources that the Diamond/CorePlayer can't handle the framerate anymore?
This really bothers me, especially when I see the Nokia E90 (having hardware acceleration on graphics as well) running 800 x 352 MP4 movies at 1200 kbps with the full 25 or 30 fps framerate, without showing difference when using A2DP.
Is the Diamond that bad with graphics or is the Nokia E90 just that good?
Does anyone know if this can be enhanced by using some tricks?
Isn't there any way to improve the video fps when using A2DP?
Videos play fine, but just with A2DP on the fps drop.

Not to derail your thread but did you find a solution to get a smoother playback? as in removing the small noticable stuttering? it makes me crazy ;-)
what program and settings do you use to convert videos for the diamond?
A2DP is quite CPU intensive, so if in addition you have a high-res movie, you SHOULD expect it to stutter.

don't know why but everything is very smooth for me. maybe yr headphones are to blame, maybe yr ROM? am i lucky?
edit:
i have to correct myself. didn't try 640 x 480...my bad, apologies.
Greetings:
Over the years I've owned many HTC devices and have always used them as a media player as its main secondary function, usually with CorePlayer as my main software. The one thing I noticed was that when it came to playback, all of my non-Dream phones were relatively quiet (very low noise/artifacts) when it came to music playback.
Ever since I got the G1 (running stock, no mods) I've noticed that there's a huge difference in the audio section-when using the wired adapter, I get lots of noise/artifacts (very noticeable with low playback volume) and I get an incredible amount of GSM chatter (which was rare in my other devices.)
Anyone else noticed this? Any fixes/workarounds? (I'm waiting for the Android port of CorePlayer, maybe that might fix some of the quality issues>)
Audio quality is something that the G1 lacks in my opinion right out of the box, compared to other mobile phones. If you have a rooted mobile though, I would have a look at the Meltus Audio mod (had a look at my signature).
The new V6 version of the audio mod increases audio, clarity and adds a bit of bass

I've noticed it a lot as well. Unfortunately, this has been both out of the box (stock) and rooted with any firmware whatsoever. It's a lot more obvious in my Bose earbuds, since they're noise-canceling, but it's unavoidable all the same.
I haven't tried Meltus's full app yet, just the lite version on the website, but as we speak, I'm on the Market buying it :]. But I've heard it's nothing but amazing, so I would give that a shot too.
Along the same lines, when ripping CDs or converting audio files, what would the ideal bitrate be for use with stock headphones?
The reason I ask is I'm under the impression that if we encode at too high of a bitrate, it will do nothing to increase the sound quality but will suck up more of our limited phone memory (not sdcard space, but useable memory for running apps). Please correct me if I'm wrong about that.

I use AAC-HE exclusively on phones-I find that using a 56 kbps conversion does a decent job regardless of the headset.
I have no knowledge of which encoding methods causes the greatest impact to running memory usage.
My friend from South Korea sent me an early birthday gift and low and behold it was a cool Chromecast key :victory::laugh: WOW THANKS but... I have a unique setup a 180" screen and Projector. This AMAZING projector (W7000) has no audio out and no way to utilize audio from Chromecast :crying: How sad... Well I discovered these audio extractors to get audio out but frankly I would love to retain max color, 3d, and 7.1 on DD+ this is not going to be easy. Then I got to thinking how come no one has developed an app which can sync the 2 outputs (multicast) from DDWRT or other at the router / gateway. Or in another way perhaps.
Two questions remain
1) Audio extractor where can I get a cheap but good one ? (seen them exceeding 200 dollars common)
THE BIG QUESTION IS
anyone know how to do this yet or perhaps if I should sell the thing and get a different setup for these projectors I have 3. (kinda committed to the output device already hehe.):cyclops:
This is what I used because the Chromecast wasn't compatible with my TV. (I had video but no audio)
www,ebay,com/itm/291119088532 $29 - has optical audio out.
Impossible to sync audio to two separate sources that are networked...
What you really want to do is get yourself a good AV Amplifier (with HDMI Inputs), not an Audio Breakout.
You will get full Surround support and would plug the CCast into the Amp and send the video from the amp to the Projector.
To answer the second question in your subject, root won't help you here. As @Asphyx said, it's near-impossible to accurately maintain A/V sync between separate networked devices. It requires sub-second synchronization and without some other constant reference not subject to network transmission delay it's very prone to failure.

Don't want to loose the 3d though and according to Wiki (not their ad on ebay) there is no 3d until 1.4 : so how come they are advertising 1.3 with 3d ?
Ohh btw does this device work 1:1 for lag or is there a few ms' wait ?
Thanks guys this really helps

AFAIK Chromecast doesn't support 120 Hz output (so no full-res 3D), though side-by-side 3D should work on pre-HDMI 1.4 as it's not doubling the rate to get L/R.
There shouldn't be any noticeable lag introduced as it's simply a de-embed at the endpoint.
I tried recording myself playing a guitar and the sound coming out of the video is terrible! is there any fix on it? gsmarena even knows the problem http://www.gsmarena.com/xiaomi_mi_5-review-1411p7.php http://www.gsmarena.com/xiaomi_mi_5-review-1411p9.php I have a rooted device with an unlocked bootloader btw
this is very interesting for me since i want to use the phone often for audio recordings. i am just wondering why no other review made this conclusion yet.
the sample video at gsmarena sounds like it is impossible to record a clear audio stream with the camera??
did you try a third party camera app for testing? i just want to know if its a hardware limitation or a weak camera app.
Hi, got a Huawei Mate 10 Pro BLA-L29 8.0.0.136(C185) and a Shanling M0 as a Bluetooth receiver. When I get them connected using LDAC, there are two menu sections where I can set the audio quality to be fed to the M0. One is the Developer Options where, apart from selecting the BT codec itself, I can set sample rate at 44.1 to 96 kHz, bit depth of 16 to 32 bits per sample, and stream bitrate at 330 to 990 kbps. These settings behave in a weird manner, always reverting to default every time I disconnect the BT or even while it's connected. The other instance is the properties of an individual BT device where I can set the LDAC playback quality to either "Optimized for audio quality" or "Balanced audio and connection quality".
Problem: if the BT device is "Optimized for audio quality", I only get decent transmission if stream bitrate is set to 660 kbps or lower in the Developer Options. Inversely, if the latter is set to 990 kbps, it only works decently if the device-specific setting is "Balanced audio and connection quality". If both are set to maximum audio quality, the playback starts gagging violently, interruptions happening up to twice a second if the phone is active and like once every five to ten seconds if the screen is off (the two devices 5 inches away from each other with nothing but air between them).
I brought the Shanling M0 to the nearest Sony store and paired it with a demo phone with LDAC audio quality set to 32/96 at 990 kbps and it worked like a charm without a single hiccup.
Anyone else has this issue and/or aware of a fix?
I have been to a number of stores since the original post and was able to pair my Shanling M0 to various devices:
1. Huawei P20, Android 8.1, Bluetooth 4.2 - same problem.
2. Samsung Galaxy S9+, Android 8.0, Bluetooth 5.0 - no problem.
3. Samsung Galaxy A6, Android 8.0, Bluetooth 4.2 - no problem.
Apparently, Android version is not responsible for the malfunction, neither is Bluetooth version. It's the manufacturer.
Crap, crossing fingers about having this issue fixed. Have you reported it to Huawei customer service and Shanling's one ?
Thank you for the feedback. I'm interested in this small DAP (nostalgic for my beloved Sansa Clip), even if I'm quite sure I probably won't use the Shanling M0 as BT receiver.

If you ask me, you should just grab your money and go get it, because it works fine with other phones than Huawei. Even with mine, if I set it to "Balanced audio and connection quality", it's doing great. Actually, the LDAC standard bitrate of 660 kbps is amply sufficient to deliver music from major streaming services like Google Play Music. Whatever the problem is, I don't believe it's Shanling's fault, because the intensity of gagging depends heavily on whether the phone screen is on or off, which has nothing to do with connection quality.
As to the DAP itself, I find its sound signature and stage presentation nothing short of amazing, at least on par with my favorite Hidizs AP100 and far better than vivo Xplay6 or anything else I tried. Sansa Clip+ is nowhere near. The way I feel right now, I'm far more likely to ditch the Huawei phone than the Shanling DAP, because there are reasonable alternatives to the former, but not the latter.

Indeed, I started following Head-fi.org's thread few weeks ago, this device looks great.
I currently own a Cowon Plenue D for more than 2 years, I'm quite happy with it: relatively small, great battery life and sound. But I'd like to have a smaller good DAP I can bring with me when I run, or simply don't want to suck smartphone's battery. I bought a Sansa Sport Clip+ (BT DAP) one year ago, crappiest DAP I ever met...
What's your battery life experience using BT head/earphones wiht this DAP ?
Hello there,
Just to share the using LDAC experience with a mate 10 pro (BLA-L29 145 (C432))
I have a Sony headsets (WH-1000XM2) and it works just fine, I'm able to use LDAC perfectly, sound is very good but you need to be close to the phone, 5m apart and it starts to break.
I know its not the same situation, but this is my experience.
Best regards.
And the volume?
Mine with my sennheiser 4.50 BT NC is very low..

I have no such experience, I only use M0 as a BT receiver with wired IEM connected to it. I never even bothered to measure battery life, since it's more than two days of my regular use, i connect it to a USB port earlier than I need to charge.

If you want to control volume on your headphones, you need to set it to maximum on the DAP. The rest of it will be the responsibility of your headphones' integrated amp - if the volume's too low, then it's just not powerful enough, there is no way a bluetooth source can fix that, as it does not transmit loudness.

Thank you very much indeed, because that's exactly the diagnostic step that I missed. Need to try that to locate the problem more precisely. Are you sure that the LDAC playback quality setting in your bluetooth device options was at "Optimized for audio quality"?

With other smartphone is working perfectly and with strong volume.
Where is possible to maximize the volume on the DAP? Simply with volume buttons?
Thanks.

I would suggest that you go to the Shanling M0 thread on head-fi, there's a company representative on that forum who's very cooperative, you should describe your issue to him. I wish I could give you a hand, but my experience is limited to operating the volume wheel on the DAP.

Yes... it has to be... or it wont use LDAC at all... it will use APTX or something else... LDAC is only used on the setting "Optimised for audio quality".
