Audio Latency with all Emulators - Shield General

Hi guys,
I received my Shield this week, I bought it only for RetroGaming. For this reason I already have some android consoles like JXD S7300, Xperia Play, iDroidX360 and Archos Gamepad, I'm looking for the perfect emulation on a portable console .
First thing, the Screen of the Shield is just Excellent ! And controls are top !
But as I feared with some comments, this console has a noticeable audio latency with all emulators...
I tested all emulators (retroarch include) and all have a noticeable audio latency. I compared with my JXD S7300, and the audio latency is unnoticeable on it.
With the .EMU SUITE like Snes9X EX+, NES.EMU etc. I can set the Sound Buffer to reduce the audio latency, but if I set this parameter as minimum I have many sound cracking with frameskip=0 (for constant 60fps), sound cracking I don't have on my 7300 (I tried to overclock and fix the CPU Frequency at maximum with SetCpu and set to Performance, but same thing, even with the 2.55Ghz Kernel).
For the same audio latency as my 7300 I need to set the Sound Buffer at 3 on my Shield and 10 on my 7300, if I set 3 on my 7300 impossible to see any audio latency, on the shield, with the Sound Buffer at 3 I still notice an audio latency...
So my question is, have you an idea of what is the problem on the Shield and if we can resolve it by a custom fix or other if Nvidia won't ? Also a setting on RetroArch to reduce the audio latency.
Thanks for your help.

same here....
main reason i bought the SHIELD was for retro gaming, but i have the same audio issues as your having.
i never had these issues on my Xperia Play or SGSIII.
this combined with the weird D-Pad sensitivity (it seems to act more like a analog stick and i have input errors all the time) has me wondering if i should sell this thing on ebay... as it just frustrating to play right now. ive honestly havent played on it in a week and went back to playing on my DSlite.

Yep, me too, if Nvidia in the future won't release a fix and if we can't find a way to fix this issue I think I'll sell my Shield (easy in France lol) for a Wikipad 7 or the new JXD S7800 because I only want use this console for RetroGaming, so if I can't because a sound issue, no way for me...
At this moment I prefer use my PS Vita (with VHBL) for GBC, GG, SMS and Genesis roms because the emulation is very good without any audio lag and the screen is almost as good as the Shield screen.

It is my hope that some of the problems are because the tegra 4 is new and some optimizations will help improve the situations a little bit.
As for the d-pad I found after wearing it in a little bit through playing lots of games it's improved a little bit. It's still not perfect but I barely notice the awkward sensitivity that used to plague me when trying to run and slide in games like Mario lol

i hope so too. i really do love this thing. i know its basically still in "BETA", but between the 64gb SD card issues, audio lag and the D-pad im regretting the $300 i spent on this right now...
i feel by the time most of this stuff is fixed there might be another price drop...
ahhh.... the life of a tech addict.... :silly:

FWIW I haven't had any audio latency issues with PCSX in Retroarch.
Android 4.3 had some significant audio latency issues resolved (there's a Google I/O talk on it) so that may take care of your issue when that OTA comes.

Hi guys, I installed Caustic 2 on my shield, it gives a very good idea for audio latency.
Go to the menu and result of latency for the Shield: 128ms ! Horrible lol
My JXD S7300 has 86ms, and the audio latency is unnoticeable, above 100ms it's noticeable.
Some owner of the Nexus 7 with android 4.3 also measured = 40ms.
And on my Xperia Play with old android 2.3.4 only 55ms !
But 128ms for the shield is just too high for a 300$ device...
EDIT: A Wikipad owner told me he has only 47ms ! It's great, and the Wikipad has android 4.1.1, so it's possible even without android 4.3.

another disappointing device from htc?

Hi!
First of all, I buy 2 days ago a Touch HD (im getting this week), but all the more I read, my thinks are that HD is not a great device finally.
Pros
- Big screen
Cons
- GPS Lag (ultra important)
- Video doesnt play smooth (80 90%) on coreplayer and have lag
- Camera lag and bad quality photos.
- No [email protected] videos
- Lot of devices with dead pixels
So, why buy this device instead staying on a Diamond/pro or buying a X1? If I stay, I only lose a bigger screen that not cost 600€ for me (usb from the diamond have adapters to 3.5 minijack), and if you buy a X1, only lose the big screen but wins all of the cons of HTC devices plus more ram and better battery.
So, what are your reason to buy the Touch HD? Im thinking on cancel my order on monday.
yes, cancel your order and buy an iphone , this solve all probs about camera , recording , gps lag etcetc

I doubt this ... because:
I am not sure that this big screen is effective enough. For watching movie and video, yes it is. However, for browsing the internet, without a doubt, you can see more content compare to 2.8" screen ... but is it directly readable without zooming? I dont think so ... Still nice though.

My reason? I dont know ... probably I will stick with my Kaiser ... and wait the next 3.8" WinMo ...
Or probably wait WinMo 6.5? Probably this can add some more functionalities.
Well right now i want a WinMo device and i want it with a 3.5mm audio jack, so that leaves me with two options:
X1 and Touch HD
Since X1 doesnt have an acclerometer (which WinMo7 is going to use heavily), has a recessed screen and TouchFlo doesnt play nice with it yet and since i can't use the keyboard fully in my language, i'd rather go with Touch HD's bigger screen.
GPS and camera aren't so crucial for me (for 3 years on my old nokia, i've used the camera ~10 times, haven't had a GPS and don't imagine i'll need it much (though its nice to have)).
Devices with dead pixels are covered by warranty, so that shouldnt be a problem.
And the only other argument you have is video doesnt play smooth, which isnt that good, since i plan on using it a lot, but when i asked here http://forum.xda-developers.com/showthread.php?t=443245 the guy says that non-AC3 movies from the net play ok and on one review, the reviewer was playing an ep of House on it and it looked OK to me, so i guess it'll do for me.

Actually it is. Played for 30 mins with one at a shop the other day and zoomed out everything was perfectly readable for me (though i'm young and don't use glasses, don't know about old folks (a lady at the Xperia forum returned it for that very reason)) the only thing that bugged me is that you can't click links directly from a zoomed out standpoint, first you have to zoom in, but that's Opera's fault, not Touch HD's. The guys at Opera should fix it
Which Windows Mobile phone can do that?
For sure, iPhone cant do that.
Click to expand...
Click to collapse
X1 can and it haa pretty much the same specs as Touch HD, except for the camera, maybe that's the problem.
Also Nokia N95
iPhone might as well not have a camera
its a nice phone but not the killer device it was hyped up to be, but i hope it will improve god willing when the developers have a go at it.
...Frankly speaking, you should have waited if you had been disappointed by the HTC devices in general. If you don't like to fiddle with your telephone, suffer for improvements, contribute to it and refresh your OS every week - then an HTC is probably not the better choice, many other companies make good telephones and similar sexy toys. The touch HD is, in my opinion, the most innovative personal platform which has appeared in the last years - it just misses Linux which will arrive soon...
i think that HTC telephones are a technology platform to have fun, like PCs 20 years ago.
If you were expecting an "out of the box" apple performances and finished ergonomics there is no need of investigating: i would suggest to cancel your order and buy an I***** (...oops, i cannot even write it....maybe an allergy? )
BTW, i have a touch HD already and i have been driving at least two hours with it and i continously hear about the GPS lag: WHICH GPS lag? If it is a 20 m lag, at which speed you drive?
Since there is a lot of speculation, shouldn't everybody clarify if they heard/read about a problem from internet, or they had/saw the problem themselves?

For the ones that say that I need and i****, I am not gonna buy and apple device in my life, but is frustrating seeing the same errors on every new device of HTC.
playbacks issues, gps lag, bad sound quality, etc etc
And the touch hd who can be the perfect model if they fix this, now is the same with a bigger screen, thats the problem, they sell the same again and again.
And the gps lag is not only 20 metters it is maybe more than 40 50 in some situations and the gps lag of the diamond have made me to skip a lot of detours and streets, it is a BIG issue.

In youtube you cant see much, you need to use coreplayer benchmark or so and that have about 80%, that it is 20fps instead 25 on videos, so not smooth video playing

compared with the touch pro, the touch hd is a big improvment. Battery life seems increadable - with the same use the touvch pro would have died hours ago and i still have 50 % left!1 Gps sensitivity is as good as my old kaiser - the touch pro could never get a lock indoors.
Not sure what htc have done, but its all good.
Coreplayer says 80% so the video playback is bad?
...
lol
Ok.
TonyPlayer says 100.5%.
All these reports of crappy video playback are starting to worry me, that's one of the main reasons why i'm buying it...
Why do you use CorePlayer when WM6.1 comes with Windows Media Player ?

Dear Kersh,
i don't understand what is real and what is speculation: which sound quality? which lag? which playback issues? which etc.etc.?
I have been driving with it on highways, city and walking my dog. I couldn't see any lag. If the diamond had a lag (i don't know) you should not extrapolate that the touch HD behaves in the same way. Please let me know of a conclusive and quantitative test you'd like to see and I'll try it out.
I have one and i am very happy. At the same time, software improvements on such a machine can make it improve even further and extend the satisfaction of owners for years. In my opinion, this device offers the best performances which are available on the market today.
My old trinity improved a lot with time - thanks to the people here trying hard to improve these devices!
By the way, I don't believe that Iphones are bad at all - simply they are like Apple PC: good for my mother and my wife - but i want to be at the frontline and contribute to it.
All the Best,
Let's make it clear iGO v8.3.1.57021 corrects the lag ! and many more improvments

Dear pzucchel,
as u mentioned in the second paragraph,would u be kind enough to do some simple test for the gps lag issue.can u drive at a speed of 80 to 100 km/h,when you physically reach a junction or an interchange ,where is the current location(i.e car icon or triangle) of your device showing? if its exactly parallel to the junction or interchange,than there is no lag..the difference between your physical location and your device location is the actual lag.Another simple test is when your car has physically turn into a junction,how long would the device take to show you are now driving on a new road and direction.and if you could be kind enough to specify what navigation program you used for the test..that will be wonderful.
Thanks in advance for your help
I've been looking forward to the touch hd for a bit now, and I still plan to get it. If there is anything i have learnt from these forums is how a lot of problems is software based.
Anyway, one main reason i'm getting it is that chance to have android on it when it gets ported on.

It depends on the software you use.
I have tried Garmin XT and iGO 8.3.1 on my HTC Trinity.
The Garmin was always a little bit behind, where iGO was always on spot!
And guess what:
I have tried both on my Touch HD, and have exactly the same findings!
I too like Android OS on the cell phone. I have been trying to tolerate the Sammy i760 I am now using, but the HD and the Omnia 16gb both look good. I also am thinking of the Invidia Tegra 600 series as it WILL play at 30fps. Would this be the "one" to wait for? or is it in something and I don't know due to all the Dr's I have to see and travel too? Thanks, JASTECH

[BOUNTY] Injecting PSX Images into Native PSX Emulator - $280+

** I haven't been around to keep this thread updated. Thankfully, AriStar has done a great job maintaining an extension of this thread over on the developers board. For the most updated status, please follow this link: http://forum.xda-developers.com/showthread.php?t=1097428 **
I'm looking start up a bounty to get a development effort going around the Native PSX Emulator that comes on the Xperia PLAY.
The preloaded Crash Bandicoot as well as the selection of PSX games available from Sony use this native emulator, the performance in which is PERFECT, compared to FPse and PSX4Droid which have sound and choppiness issues at times.
Some discussion on this topic is in another thread, here: http://forum.xda-developers.com/showthread.php?t=1044755 . We can see the psx image on the SD card with little effort, however the formatting of this image and the steps required to inject our own images is still unknown.
My ultimate goal here is to be able to run FF7 in the Native PSX emulator and support the disc changes needed. (From the PSX Emulator menus, disc swapping looks to be included, but as no multi-disc games are released, this may be tricky).
I'd like to throw in $20 to start this bounty and get discussion going.
Please post under this thread if you can contribute either to the bounty or to the development effort. If you have any requirements attached to your bounty contribution (ie: "Must be able to play FF7") then please include those as well.
Bounty now up to (or over): $280 + Xperia X1

Disc swapping is probably less of an issue than it sounds - you only have to swap discs once every 10-12 hours for most games, and almost every single game that has a disc swap also lets you save after completing the disc and before the swap, so in theory if the PSX Emulator only allows for once disc at a time, you just make a wrapped image of each disc, save when you hit the end of one disc, and boot the image for the second/third/etc disc and voila.
While ultimately it would be a great feature, it's probably not strictly necessary and will amount to a minor nuisance in the short term.
Also, put me down for $10CDN towards the bounty as well.
10 Euro more. As long as it works, I'm cool with it.
Nice idea.
But my games run perfect in fpse.
Tell me what games you find choppy and i'll test them for you. So far i've played -
Time Crisis (touch screen as light gun, dam awesome)
Demolition Derby
Rampage Universal Tour
Point Blank (touch screen as light gun, dam awesome)
Strider 2
Die Hard Trilogy
and they all run flawlessly.
Would of tried more but i've been hooked on the nes/snes/master system/genesis and native xperia play games (backstab/nova2 etc) for the last month.

The one I care most about is Final Fantasy 7. Battle sequences tend to be choppy, the sound slows to a crawl when coming into and out of battle. The music sound sync in general also just isn't perfect. It's "good enough" for the most part, but stammers a bit, feels like a beginner drummer that can't really keep time.

Yeah sound emulation is more difficult to do than it seems. A ton of emulators (even today's Gamecube/Wii emulator, or the PS2 one) have sound issues more than anything else.
Also, I'll throw in $20 CAD for this. Hopefully it's actually possible and Sony's emulator is actually already complete. It'd be a shame to crack it but only find out it needs to be patched by Sony anyway.

Yeah ive turned on sound sync. It helps but the sound is not accurate. It eliminates the stutter but the actual sounds are inaccurate, plus the graphics arent smoothed and are overly sharp and a bit ugly. Compared to the smoothed graphics of the official Sony emu they look poor. PSX games run at 1/2 the res of the Xperia screen so smoothing is essential. Fpse slows to a crawl when smoothed
Fpse is good, but still has a way to go before its good enough for me to use for everything.

I'll throw in £5 UK into the bounty.
Thats about $5000 US isn't it?!

Does the XPlays native emulator really have smoothing? I did think that Crash looked better than I remembered but put that down to the small screen and the fact that last time I played crash 1 was on a large HDTV.
I dont think it does, sony erricson has already done alot of things in an attempt to save the phones battery life (like the whole no autobrightness off thing)
I doubt they would add smoothing as it would get use up more of the CPU thus draining more battery life.
The only advantage I see with the official ps1 emulator is that fram rates are excellent and there are no graphical glitches.
Correct me if Im wrong, wouldn't one advantage be that Fpse doesn't really support the dual touch pads, but the native app should support them for any game launched through it.
Also for an update,
bounty is at 20CAD+10CAD+10Euro+20CAD+5GBP

or about
75 US Dollars if u think in those terms .

It does smooth, trust me - playing Wild Arms is proof enough for me - the graphics are softer and less pixellated than in FF7 via FPSE.
I'll see if I can take some comparative screenshots of Wild Arms in the Sony Emu vs FPSE (as I do have WA on CD as well) just to be 100% sure, but I'm already 99% sure it smooths (is that a word?).
Besides, smoothing wouldn't add that much hit to the battery - you're basically just talking about the bilinear interpolation function of the graphics chip, which is a pretty minor hit overall.
The reason FPSE chugs when smoothing is because FPSE is a generic Android app, written to work on ANY Android phone - so it probably has NO hardware GPU access at all - which in my opinion is pretty lame and shoddy programming. There are, what, like 30 different graphics chips currently used by Android devices? If I'm correct, they'd basically have to write in detection and calls for every chip into FPSE.
Whereas the Sony emulator was written explicitly for the Xperia Play and its hardware (the Adreno GPU). That's why it's 10x more efficient and faster than FPSE, and why it can turn on smoothing and still run better than FPSE does.
I know, my first post but trust me Im good for $10CAD
count me in for $10 CAD
put me in for $20USD
put me in for 10 AUD

Opengl should solcem ost of the problems of the multitude of gpu chips there are as the calls to all the gpu's would become the same.
Also, to reply to an earlier post, the touchpads will probably be supported in a future version of fpse, probably the devs don't have an xperia play just yet.
The game ISO is in a file called image.ps and appears to be encrypted. That encryption will need to be cracked before we can do any sort of injection of PSX ISOs.
ill throw in £5 GBP ive tied reverse engineering the app, tried and failed; i dont know what source code their using, but i cant get it recognized by anything so far!

Audio Latency

could someone with a nexus 7 run some audio latency test, im planing on porting the pulse audio driver as it has been confirmed the nexus 7 uses linux alsa so the port will be fairly straight forward, it has been proven to provided better battery life (only marginally) and use less cpu. By taking fixing the re sampling between 48 k and 44k of the tegra 3.
Don't yet have the N7, but I've been running JellyBean on my Galaxy Nexus for 2 days, and can confirm the audio latency is MUCH lower than when it was running ICS. Before, when using synth/music apps with keyboards like Caustic2 there was noticable lag between the time I'd tap a synth key, and the sound would come out. The delay is gone now.
I can confirm that there is no perceptible delay.

I can still hear a delay. the goal is to have no (tap)(sound)
probably about 80ms lag
For those german readers:

shortened:
ICS: >100ms
JB: 12ms
iOS: 5,8ms

Thanks for the video, but that is definitely too latent to do any recording/studio work with. At least for me.

Technically that video is illustrating touch latency+app latency+audio latency+sample ramp-up

Very cool. I't always good to see an 'engineering type' thinker. Hmm, wish the OP ( programmer ) would respond. Butter made it eight times quicker ? But I guess he's waiting for h/w like most of us are.
if its true that latency is 10- 12ms ( i presume thats app>audio out not audio in>audio out, not sure at this time) then that should be acceptable for playing instruments and real time monitoring for recording.
for Latency snobs, 12ms equates to the delay standing 12ft from the source - alternatively, i remember reading the original Hammond Organ, due to its electronics, had a latency of 13ms and people didn't get too upset!
good news as do hope to get some audio use from the nexus, but have to wait for worthwhile apps, ios miles ahead in that area at the mo.
The audio latency is 72ms according to Caustic. That's still pretty bad. It's definitely perceptible.
A user named Windows X created a mod for the Nexus S that lowered audio latency significantly (see here), and then vonVideo created a mod for the GSM Galaxy Nexus that brings it down to around 20ms (see here), perhaps someone could have similar success with the nexus 7.

[Q] OUYA Dealbreaker - Input Lag

Anyone experience noticeable input lag on both the stock controller and Dualshock 3? Is there any fix for this? Or it is simply bad design on OUYA's part rendering it useless for gaming (it's intended use).
It is definitely not my setup. On my HDTV I have 120Hz off, it set to Game Mode, and all the other recommended tweaks. Also PS3 plays on it wonderfully with no noticeable input lag whatsoever.
While the OUYA is a mediocre device in a lot of ways, it seemed worth it for $100, but input latency is the most basic of functionality, especially in gaming where extremely responsive controls are absolutely required.
Turn OUYA on its side. I have not had lag since I did this. Cools better too.

Lol
My lag has improved though, I went back through all the recommended tweaks from various sites, and am now using the Dualshock 3 on bluetooth, overall a much better experience now.
Never noticed any lag, but if your TV even has a "game mode" then it's probably your TV.
I have found that I had controller issues in some rooms but not others, I had a wireless mouse in the same room where I suffered problems, so I pulled the batteries out and made sure all other electrical equipment was turned off and it all worked fine, clearly other equipment was interfering with the signal.
When running correctly I don't experience any lag as such from the console, or it is so low that it doesn't have any affect on my gaming.
Some gamers mistake the existence of dead zones on the controllers as lag, the sticks don't register a movement until you push them so far. Also some games have lag because of bad programming or using old/incorrect controller plugins, most are fixed now though.
Hope that helps...

[Q] audio latency

Hi everybody! I don't know exactly if this is the correct forum to post my question, but there it goes. For some years I was a iphone user, and what made me stay for some time with iphone was the ios low latency capabilities. There were a promise that the S Galaxy series would, some day, be able to deal with low latency audio processing.This did not happened yet. Does anyone have some news about it? I have now a Galaxy S5, and I really appreciate the possibility to connect my guitar into my smartphone and add effects in real time. Thank you very much.

I hadn't heard much since Raph Levein's presentation on high performance audio at Google I/O 2013. But a quick Google search answers your questions.The top three search results cover all the bases and seem aptly ordered as well.
