Sound Buffs! Output on Windows 8.1 devices / tablets? - Windows 8 Development and Hacking

So i'm curious if anyone has tested the output of any of the windows 8 or 8.1 devices to see if there is any roll off in the mid-bass / sub bass frequency range?
I know my old android tablet used to roll off around 100hz and I'm curious if the windows devices do the same, or if anyone has found a way to bypass the internal DAC or trick it into letting you have a full 20hz - 20khz range of frequency

Yes, I did test it on my DELL Venue 8 Pro. I opened Windows Media Player in 8.1 and played a standard test file that I usually use. The software equalizer was then manually adjusted to remove (negative gain) all frequencies above 200KHz. As I started going below 150Khz, I realized there was nothing audible coming from the mono speaker.
I'll leave you to deduce your own conclusion from my DELL Venue8Pro. It's not a deal breaker for me, since I use headphones when I want to listen to audio. However, the Venue8 Pro does not come with a built in amplifier to pump any serious bass into my studio quality headphones. Even the battery operated beats headphones didn't sound good when I had plugged them in. Only the "mid" region had a good quality sound. When I plug the same headphones in my Samsung Galaxy Note2 or HTC oneX, I get the bass I want.

I generated a sine wave sweep in Audacity on my Toshiba Encore tablet, played it out the headphone hack and recorded it on my computer's line in jack in Audacity. I used a range of 20Hz to 200Hz over 20 seconds. The overall amplitude of the waveform received on my computer looks the same over this range, there may be a slightly lower amplitude from around 20 to 40Hz, but its only slight. Not sure if this is being caused by the audio cable, the tablets DAC output or my computer's DAC input. When played on the tablet's speaker you can barely hear anything. I hooked it up to my stereo system which has speakers that go down to 50Hz and the sweep sounded fine from 50 to 200Hz.

Audio tweaks when root is achieved.

So, I'm a little underwhelmed by the DAC on this phone. It's mainly the volume. My Note 2 with DAC tuning and V4A sounds much better and is much louder.
Assuming we get root, will we be able to tweak the audio down to the DAC level in terms of oversampling, tuning, etc? Would we just be stuck with V4A and other software based optimizations?
Ideally, I'd like a louder headphone jack that doesn't suffer from as much distortion when turned up. My main issue is that it just isn't loud enough for me.
I'm using Klipsch S4's and ATH-M50s. I do plan on adding a pair of RHA IEM's or another pair of full size cans.
I know that people are using external amplifiers successfully with the phone, but I'd rather not carry one around if I could squeeze more power out of the DAC post-root.
Thanks!
I think it would depend on whether its done at the kernel level or at the chip layer (either from a soft processor or actually part of the HDL code fabric). Then again I no know nothing about audio DACs so it might make sense for them to expose those level of hooks to the kernal or even software/rom layer since they're often times needing to be tuned to a speaker's performance for achieving a desired sound (hopefully).
If this fails maybe it might be worth adding a outside box DAC from Fiio (those are good, I have the same headphones, ATH-M50s, and they do improve the sound even with v4a especially if you're seeking higher audio volumnes) or maybe even an USB Audio DAC (I would suspect these are even better than analog <> DAC <> analog ones) which will newly be supported natively by Android L and maybe already by Samsung phones.

Hope that might help, unfortunately I doubt we'll see the level of tuning capability that you're seeking. I don't really know much about qualcomm's audio DAC selection but those with exynos phones I know have those really nice premium ones. It's all up to the hardware's capability and for all we know qualcomm's DAC has some crappy sampling rates which will never be able to be improved on if you're looking for good audio directly out of the jack.

Thank you, definitely helps. The audio output on this phone did get some good numbers according to GSMarena. I'm hoping that it means further tuning is possible. I believe the HTC One has a crazy 2w audio jack that's both loud and clear and also utilizes the same DAC. Hopefully that's a good sign for the possibility of tuning on this phone.
I was considering a Fiio box. I just hate having to carry that thing around or keep it clipped somewhere. The native USB audio out in Android L sounds promising though. I'd assume that a smaller USB sized box would leave a little less of a footprint.
I think Samsung actually ended up losing a lawsuit due to hearing loss. I suspect that it may be a reason why the audio output on the Note 4 is intentionally crippled. Hopefully I'm right and hopefully it's reversible.
I miss the Wolfson DAC on my Note 2. That thing sounded incredible. I'm tempted to sell this and seek the Exynos version just for the audio output.
When you use your m50s directly from the audio jack and through v4a, are the volume and distortion levels and better when cranking it up?
Oh, I also think that a file exists on the phone that limits the decibel output on the headphone jack. It can be altered to a level of 63 vs the 56(ish) that it's currently set at. I remember doing this on my Note 2 and it helped with high volume distortion quite a bit.
Root, we need you root.

[Q] Behringer UCA202 DAC - sounds horrible compared to headphone jack/bluetooth

So I found a Behringer UCA202 DAC online for really cheap and thought why not try it just for fun. Everything I've read says having one can help a bit and I figured at the least it would sound the same, but I plugged it into my Nexus 5 via OTG then plugged the AUX cord to my Jeep into the DAC and all bass and pretty much any other level of detail is gone from my music whether it's from Pandora, YouTube HD, or FLAC audio files. Audio sound quality is equal to listening to music over old mono bluetooth, you hear it fine but any highs and lows are removed. Has anyone else used this DAC that could give some suggestions?
Otherwise it's just as I assumed, DACs are pointless on good quality phones and that's why I can't find any DAC threads with the Nexus 5 involved.

Yes it has a DAC but it's not meant as a stand alone DAC. It's an interface or soundcard. Does your phone have enough juice to even operate the thing? Also for a device that sells for less than 30 bucks what exactly where you expecting? Get a real DAC. You will notice a huge difference. Until then do some more research on what you have and see if your meeting it's power requirements.
This is actually a pretty good review of the unit with lots of technical info.

While I can't see power being an issue I suppose I'll test with my Nexus 7 and laptop. I know it's a cheap DAC but I've read many reviews using this DAC with tablets and phones for car audio, along with the nwavguy in-depth review and testing showing how it's not a multi-hundred dollar unit but still does amazingly well. My issue is it doesn't even sound decent. It sounds like I'm playing rap/hip-hop through an old Nokia on speaker phone, you can hear it clearly but there's no depth.
So I tossed this DAC in a closet after I got bored of trying to make it work right and forgot about it for a year or so till earlier today when I found it while cleaning. My Nexus 5 has been retired and serves no purpose other than a security camera now. I now have a Samsung Galaxy S5 and an RCA Maven Pro tablet. The RCA Maven Pro is an 11.1inch 2-in-1 Android tablet with detachable keyboard for around $120. You'd assume it's horrible thanks to the brand and price but they managed to cut corners in all the right places it seems. Downsides are no GPS, 1GB of RAM, terrible cameras, and a horrible speaker. Other than that it has faithfully replaced my $1200 laptop with zero issues other than adjusting to ditching Windows.
Now back on track when I listen to music I'm either using an aux cord plugged into my work truck or bluetooth when using headphones or in my new car. When doing a side by side comparison bluetooth, to no surprise, shows no difference between my Maven and S5. However when using an aux cord the RCA doesn't put out as much bass and highs are... I guess not as clear? I think audiophiles are insane most of the time so it's hard for me to describe when I do notice a difference. Anyways I plugged the UCA202 into the RCA's USB port (no OTG here, it has a full size USB port) and plugged my Sony MDR-XB950BT headphones in to it with an aux cord (these headphones are 100% passive when wired, no bass boost or other enhancements) and sound quality is just as great as my S5, all bass and highs are restored. Just to further the test I plugged it into my S5 and did the same test with the same results. These are the same FLAC song files from the same network location that my Nexus 5 was playing a year ago.
The whole time the issue was something in my Nexus 5. What it was I don't know and sorry you guys I don't plan on investigating, I just wanted to inform everyone that the Behringer UCA202 is in fact a quality budget DAC since this thread is a top Google result for "Behringer UCA202 Android". If you have a cheap device that you want the audio to be on par with the high end phones this will do it, and for my original purpose of at the same time giving a bit of amplification for a weak head unit without distortion it does that decently too. To finish this off I am NOT an audiophile. Just a human with human hearing that likes songs with bass on car head units that weren't always designed for it (I glued a 80mm CPU fan to the back of the HU in my Jeep ) So take my finer details however you'd like.
the DAC works great for my Nexus 7 2013 model.
maybe otg cable is sh1tty

My new Audiophile headphones problem.

Hello, I am very much kind of headphone lover guy.
Recently, I bought Beyerdynamic DT770 Pro 32Ohm (32Ohm version for portable users).
But the sound is not coming to its best. I plugged the same headphone to iPhone and it's working awesome. iPhone quality is same as it work on macbook and PC.
So, I was worried, is my headphone supportable on my Nexus 5 or I just have to invest in buying mp3 player.
I will provide link, where you all cann see the specifications and tell if that is supported on this device or not, because I am not that much of technical guy.
Headphone Link - http://north-america.beyerdynamic.com/shop/dt-770-pro-32-ohm.html
I have rooted my phone and is currently running on ElementX kernel and Chroma ROM.
Hope you guys can help me.
Thank you.
Is it quality that's bad or volume level? Or a bit of both?

More of a volume. The quality is good.
Try this - https://play.google.com/store/apps/details?id=com.n5rvb.nexus5realvolumebooster
Also i always use poweramp with the preset set on rock. Always find it the best sounding

Install any kernel management app, like kernel adiutor, and in sound menu raise headphone gain.
So I just did what you said. I already have paid version poweramp and installed volume booster, set it to 19 and 95 for headphone and speaker. Set my present to rock, but I was just little curious, are you also facing a little distortion in the sound or just me? Because I think, I can listen the distortion, maybe because these are kind of Audiophile headphones, so they are giving deep detail of every sound.
As far the volume matters, its 2.00AM, so very much silence environment but I can definitely feel the volume is increased.
How much did I set the headphone gain too?
I already installed the volume booster app, should I also gain on this app too?
Try these!!!!!
These are the "loudest" and best in-ear buds you can get!!!! http://amzn.com/B00WI79EK0 They are Zorloo "Z:ero". Forget about booster apps, eq apps, etc... This thing has a inline "DAC" it plugs into the "USB" port and not the 3.5mm jack. Read up on it!!! I have wasted money on many in the ear, over the ear, everything under the sun to get the best sound and these are my latest find. (Thanks to an article about the Nokia 808 and how people are pimping them out). I cant say enough how LOUD!!!!!!!!!! they are.
YOU WONT BE DISAPPOINTED!!!!
I think they are lurking under the radar because its not a "Brand" name like Shure, Whitestone, or any of the "high" end stuff people are used to paying 100's of dollars for. But the technology using "DAC" has been around and if your looking for something to drive your "over the ear" stuff maybe a usb cable micro to mini adapter and then a USB DAC Stick might work for you... I am sure you can also try to "hack" the "Z:ero" by cutting off the "ear buds" and then going to the local "radio shack" and getting a 3.5mm stereo input jack and soldering the four wires to it and you just made yourself a custom low cost "DAC"...
Just a quick review I google...

Try them!!!
Install viper for android. It helps with the sound processing on the N5 immensely.
I was going to say something about the impedance, but my headphones are a higher impedance than that 35ohm, and I'm pleased with the quality and volume. I know you are not looking for just volume, you are looking for volume and quality. Something I found in the past with some of the Android EQ settings (didn't matter which app) some of the settings like bass boost, would actually lower the volume coming to my headset.
A good set of headphones shouldn't have to have any EQ settings changed at all, leaving it on flat should be the best, and for preference, you can always use flat as a reference.
Every headphones is different from others: if you want a boost in volume/quality, you should try an amplifier like FiiO E6 (http://www.amazon.it/FiiO-E6-Amplif...6?ie=UTF8&qid=1439893840&sr=8-6&keywords=fiio )
32 ohm is a bit high for a smartphone, so there is a possibility that Nexus can't handle that well.
I have a pair of 32 ohm dt770 as well as 32ohm mmx300 Beyerdynamic. They both work fine.
They definitely shine with a good headphone amp, but if you're running without one straight to a phone or laptop, definitely get 32 ohm. It's the lowest they make for mobile type uses.

I'm listening to my Sennheiser HD 598's right now using the quad DAC (high impedence). It is definitely driving them very well, I get my Audioquest Dragonfly black in tomorrow so I can try A&B comparisons with that vs the internal audio. I've also enjoyed using it with my Backbeat Pros but those do not have aptx.
I'm using my Beyerdynamic DT770 Pro 250 Ohm headphones, it's amazing. It's a step up from the V10, including the volume department (especially with high impedance headphones).
I'm currently listening music with the AKG K712s. No doubt an improvement from the V10. The best phone yet that truly brings out the detail in
WAV and FLAC formats. I swear this quad DAC reincarnated my cans
Should be getting my V20 some time today, I hope. I don't have anything truly God-tier, but I'm going to try to do a few comparisons if I can. I've got Shure SE215s on one hand (triple-flange tips) and Samsung earbuds for a baseline, compared to whatever LG's included in the box. In a few weeks, I can add the H3s to that list, but not until they arrive, and they won't arrive until I sign up for them on the 28th, so...
In the world of full-size cans, I don't have a solid baseline, and I'm not looking forward to the idea of spending $20 so I can have a pair of cheap cans I will never listen to again. So instead, all I've got are my Koss ProDJ100s and my V-Moda M100s.
But I'll try to give my thoughts when I can. (Also, posting so I make sure I remember that this thread exists.)
---
I didn't get to really sit down and do heavy listening. Phone arrived pretty late and my fiancee was a little sad so I didn't want to have my headphones blasting for an hour or two straight without being able to hear a word.
Noticing that there is a little more clarity (at least) between the on-off settings. Might be some EQ going on as well, though, which is not what I want. EQ is an easy way to make something sound more "clear" without actually making it clearer. My last car literally had a setting that I used that I considered the "clear" setting, and for everything other than podcasts. The bass was deeper, and yet more articulated, and the highs had sparkle. Every other setting was muddy.
So EQing to a muddy sound, and then having a "hi-fi" EQ that clears up the mud isn't good. Still, like I said, I don't actually know that to be what's going on. It's just a possibility I'm keeping my ears open for.
Audio technica ATH-M50x Have to say, I can't hear a difference at all toggling on and off using Poweramp/Spotify/USB Audio Player Pro or Car with Bose speakers setup. What can be the reason? I was thinking it would sound better (or as good) as V4A. Not close for me. Maybe my phone's defective?

Not sure if they fix the issue were the DAC was only able to be used by the stock music player. On the PlayStore there's an app that allows the DAC to work with all music players. I think it's called lgv10fix something like that. You can tell when you turn the DAC when your music skips or mutes for a second.

By plugging in the detachable headphone cable into the LG V20's headphone jack first before connecting the cable to the headphones, causes the Hi-Fi DAC to go into "An External Audio Device Is Connected" mode which produces a higher output compared to "Normal" mode.

So excited to use my Custom Art Harmony 8 Pro, custom headphones with these. The V10 did a good job, I bet the v20 will be better!
For reference, here's the playlist I used to compare. I didn't want to spend all day doing tests, so this is mostly stuff I can listen to while I work, but trying to hit as many different sound signatures as I could. I don't have any classical in my collection, though probably I could have used some. I listened to most of the playlist (skipped around a little getting details) on my laptop for a little while before picking up the phone. Probably going to do some listening with the S4 mini I've got on loan from my wife, too. Would have been nice to compare the Note7, but it's already back in T-Mobile's hot little hands.

As for my thoughts:
First, I was surprised that as far as I can tell, LG hasn't included any headphones. That seems weird. I'm glad now that I have a million bajillion of the things lying around because if I just bought this off the shelf, it would be a long wait for LG to send me my "only" wired headset option. At least a few weeks. Disappointing, but not a deal-breaker by any means.
Started with the Samsung headset, Hi-Fi DAC off. It's not super comfortable, not at all isolating. I'm still listening to the last couple tracks and I can easily hear myself typing with the volume at around... well, in the Hi-Fi volume it would be 45. I should note that it goes much higher (I believe the highest is 65 or 75) but 45 is where I would typically listen to music. Louder than that started to strain my ears a little. Louder is generally better for detecting little things in a song, but I don't want to suffer, and I certainly don't want to suffer for the time it takes to listen to a 90 minute playlist 4 times at painful volume.
(Incidentally, someone above complained that it wasn't as good as V4A--I haven't listened to V4A in a long time, but my recollection was that it does 2 things: EQ and boost. All their stuff comes down to highly advanced adaptive EQ and a volume boost. Essentially an Instagram filter for your audio. That's all you really can do with a software solution, so I don't blame V4A's team, but what we're looking for with a hi-fi hardware DAC is closer to putting your glasses on if you're near-sighted: increased clarity without changing or coloring the sound any more than necessary, including volume changes. That's what your choice of headphones and your EQ settings are for, not your DAC.)
Moved to the Shures next. The SE215 has a slightly bassy sound, IMO, much better for dance music than e.g. the Koss cans. Not quite basshead cans. I was impressed by performance, and volume. I felt "comfortable" for the first half of the playlist before checking the volume and discovering it wasn't at 45, where I'd wanted it--I had it at 30! Turned it up to 45, and I was at a point where it wasn't quite uncomfortably loud. Which is to say, these things can push power to a pair of headphones no problem.
Equally surprised that the Koss cans didn't have an equivalent bump in volume from what I'm used to (which is maxed out on the Note7, and remember that I'm nowhere near maxed out on the V20). Oh, sure, I could have turned them up, but I didn't. Clarity was as-expected. Much better, I think, than the SE215s.
What I'm looking for here is silence and separation. On the country tunes, in particular, you end up with a mandolin, banjo, and guitar all fighting for 'space' on the recording, so I was listening to make sure I could make out guitar chords from banjo rolls from mandolin... whatever mandolin players do. I'm sure they're very important musicians. The other part I listened to carefully was the intro to Chandelier; There's an etremely isolated snare in the beginning, and it should fade to nothing, not fade to sort-of-nothing. I didn't get that with the Shures as much as I wanted, but I did get it with the Koss headphones.
V-Modas don't do much to change my opinion. The bass is defined, clear, not boomy. I'd say the V20 seems to have a fairly balanced sound signature, which makes sense because that more-or-less matches what I've heard about the B&O sound signature. If the V20 DAC was developed with their input, that would make a lot of sense.
So in the end, I'd agree with kms108:

Question about headphone output quality

Trying to get an idea of the quality of the output of the headphone jack. My Asus Nexus 7 (2013) has a fairly noisy output (lots of bus noise) but my Sony Z3C has very clean output.
There is a you-tube video out there that indicated that it's fairly powerful but did not indicate the quality of the output when used with sensitive headphones.
Anyone have any insight?
It might be pretty good. Only moto phones that disappointed me were/are the g series.
It's great!!
I use Neutron music player app and Harman Kardon BT headphones. I upgraded from LG G2 which used a Wolfson DAC and the first thing I noticed on Z Play was the LOUDNESS which I believe would be better at driving power hungry headphones. I also find the stereo imaging pretty awesome. The music feels more lively and energetic even on the flat eq settings.
But if you're an audiophile who mostly listens to lossless music, I'd strongly suggest Neutron or JetAudio. (both paid) This is because the hardware doesn't have a native support for many formats and therefore the need for S/W decoder arises.
I had some songs that wouldn't play on GMusic but did on Neutron. :/

Thank you for your input but your Harman Kardon BT headphones just the BT stack if I understand corrctly - so they would not be affected by bus noise, DAC/Amp etc... Have you tried with normal wired headphones?

I m using moto z play and i can say its audio quality is superb
If you are used to listening at lower volume thro' headphone jack you will notice high level of radio interferences/ background static for sensitive in- ear phones. Reason: the antenna band is too close ( a white strip over usb type c port)

Yep, I've noticed this as well
I'm using plain regular Apple EarPods (from the 6S) in my Z Play and it's gotta be one of the best phones I've listened to music on. I've heard details in the songs that I haven't heard in any other phone or speaker before!

I noticed this but to be honest: I have to turn up volume very loud (can't hear normal music with this) and wait until the songs faids out. Than, at the very end of the song I could hear some noise. I use very sensitive and rather high end IEM's (UE 10 triple fi) with low impedance (32 Ohm).
So yes there is some noise. But normally you should never hear it.

I went and installed Jetaudio + . Wow it puts out up to 192/24. There is a dropdown of current processing. I have the same Apple pods. There is a Bongoivi DPS where the earpods can be dialed in. Sans all other processing the sound is stunning. I did also set Gplayer Equalizer to off and disabled as suggested in another thread. Strange advice this is but have others found it necessary?
What output amp is in this? Surely a bipolar "chip" of sorts.
Try out this player on our phone. Do check out the pics of the likes of my source material.
The text file about an amazing 24/192 FLAC.
BTW this player adds 1 percent volume adjustments yet there is no easy way to "finger" this fineness on the app's slider
