1  Ultimate Audio Playback / Playback Tweaks and Source related subjects / Re: USB Audio Driver Registry Buffer tweak on: April 04, 2011, 12:39:22 pm

you ,yourself are guessing.

Haha, careful now. You are the guessing one, and I *know*.

Default (actually fixed as far as I know or knew) for XP is 1ms (which is not ms), for Vista I forgot whether I ever tested that, and for W7 it is infinity. I am GUESSING that for Vista it's infinity too.

Remember, I can see, measure, try, write code to try, write the audio software anyway.
So who is guessing ? not me.

Maybe your means of interpretation are different from mine, but really nothing like entering a new Registry entry will apply a "patch". This is to be read as : without applying that patch you can add Registry entries you want, but nothing will happen. So, it needs the patch first.
Next, the patch disappears, and instead it becomes a standard for the next OS version. This will include W7, unless it's taken out again anyway. Now which way do you want to go ? ... Taken out ? then it does nothing. Still in there ? then it defaults to 10ms and can next (and only now) be overwritten.
If you want to read this differently, all stops here.

What it (once again) all leads to, is that you won't know what you are doing; not because your are dumn or anything, but because you can't know what the OS does for - or to you. Remember, I *know* how it is, because I check things.

Now think further ... this beautiful tweak of yours could change your infinity into 10ms. So, you applied a change indeed. Sadly, XXHighEnd can (and will) work with this infinity figure. Now what ? You molested things.
I am not saying this *is* so, but chances are fair, if only your "tweak" still works.

Shall we now cut it out ? apply it to JR and be happy.

I will tell you one last thing, to maybe show you at last that you don't know what you are doing ("to");
Try to find latency figures from MS. This is how fast a response from buffers etc. can be, and what the best response for e.g. MIDI stuff can be.
What will you find ? 10ms.
You already know by now this actually can be 0.5ms, right ?
Or do you maybe accept that it is really (but now REALLY because *I* say so) is 1 stereo sample of 32/384 ? take your calculator. And not only because I say so, but because people use it (to be honest at 192KHz).
You want to project it onto external latency ? also fine. Multiply what you found by 48. Or by 32 for those with (RME) soundcards which can do that.
Remember, 32/384, may you get around what that actually says (referring again to your "1ms" which is not about time at all).

Now tell me again what you'd want with your xxms which I overrule beyond all MS articles.
Yeah, that you can molest your own PC with it, because I'm really not in control of everything (especially the "tweaks" I don't know about).

I really hope this is enough of it ! Happy


All that matters Pete, is that it sounds better.

Thanks, i've already seen these links before, and didn't work. USB IdleEnable that another posted on here does work.

Sadly (for you) the Registry Attribute is not there by default, while it defaults to 10ms, which is what you set it to, and now you have better sound.
GREAT.
But if you don't mind, I won't believe that. You should at least have set it to *other* than 10ms to have things in your favour. And then still we won't know.

Pete, please read carefully what i posted from MS site.
The default for XP is 10ms and 4ms for Vista. Unknown for Win 7. you ,yourself are guessing. i don't use XP, i use win 7. it is only defaulted to 10ms after installing a patch, which i have not done and this patch is for vista not win7.

and because we can't be sure what I am going to see from that (because of countries directing to certain MS mages) you are also going to make a screen copy of the contents.

Didn't you read this ? or did you maybe don't want to read it ?

Don't be too ignorant on this. I clearly said it for a reason.

Btw, if you want to attach a screen copy, just click on the "Additional Options" you see in the below left corner during posting.

I'll allow you not to have lost yet ...
Ah, good, found how to attach.. here it is. this is the info on how to change the buffer. and once again, not all info is relevant (hotfix etc etc)

Can't you make screencopies ?
blush1blush1blush1blush1

I can.

By now dutch people will know you have lost.
Now you ... Wink


Umm, you haven't captured the info i was talking about in this screen shot. maybe post the full facts about the buffer tweak.
I have won this contest. i said there was only 10 results in google using exact phrase, and have a link to the MS site. what's your point Pete? It's a USB Audio buffer tweak? i don't get what you are on about? It works, and soudns good. i said ignor other info on the MS site as it's not relvant, only the buffer tweak that is of interest. now hang your head in shame! teasing

Yes, you need a tissue. Well, for now. Happy
Where are your links ? where is your copied page ?

Instead of tissues, maybe look this this : blush1
haha
I need a tissue?? nah, you do  Happy
this is the Microsoft link
http://support.microsoft.com/kb/953228

Not all the information is relevant on this above link as it's speaking of correcting other issues regarding UBS 2 audio, but the buffer still works for USB 1 Audio devices. Scroll down to the information regarding changing the Buffer size registry  edit of the USB device. I tried it, cause i can't help myself when a computer audio tweak is involved. fortunately it sounded great.

I will give the subject a twist and see how far we come with this. Be ready to burst in tears, okay ? I am ready for that too. Happy

Btw, you don't have to coorporate if you don't like to, or have better things to do otherwise. But if you don't, you loose in advance because of not showing up in court. Notice that I loose rarely in these kind of games (which I just made out of it), but it sure can happen. As said, I am prepared for that.

Now let's see. Below you see my Google result. Not exactly 1000, but 650 only. However, this has been one means only to look for it, and there are others. Not sure if I can make it to exactly 1000, but let's say 650 is enough for now. yes

Next, you are going to provide me that "Microsoft" link you referred to, and because we can't be sure what I am going to see from that (because of countries directing to certain MS mages) you are also going to make a screen copy of the contents. So, both please.

Then, you are going to tell in here - whatever it is you think you found - what it actually does. And what it is for. Of course this should equal your earlier description, but you are allowed to deviate from that.

When you have done this, I will be back with some comments. This could comprise of "I lost" only. But maybe not. This is actually up to you and what you come up with.

Small hint : Google again what you Googled for before, and notice Phasure.com to be on top. It may tell you something.

Have fun !
Peter

Hi Pete search on exact phrase CapturePacketsPerUrb, which is what i'm specifically talking about here, 10 replies on google, and only 1 that has proper information, Microsoft site.
Thanks for playing. need a tissue? Happy
And regards to what i found and what it's for, i mention on very first post.

Once again, it is NOT tweaking an audio players code, is for USB AUDIO DEVICE which can/will influence the final sound, as with IRQ settings, USB IdleEnable, and Clock Resuloution. this is another tweak. Pete, and others, if it doesn't work for you, don't use it, at least try it out first then decide. As for this tweak being dug up from a 1000 places, i seem to only find it at one place, Microsoft website. try and google and see if a 1000 posts pop up, then tell me.

and yes, an OS is loaded with s*it like this, been building my own computers for 10 years now, with audio related hardware and software.

Hi Pete,
This tweak is as stated above, a tweak for USB Audio Devices, NOT software audio players. The tweak is to raise the data buffer in the USB AUDIO DEVICE. it is not about stutter as i had no stutter previously. Is for Audio quality and works wonders here, REGARDLESS of the playback software. Is a tweak for others to try out. There is no harm, and is not dangerous. if it doesn't work for some, just delete the registry entry. Happy
10  Ultimate Audio Playback / Playback Tweaks and Source related subjects / USB Audio Driver Registry Buffer tweak on: April 03, 2011, 05:18:08 am
Hi,
Found a tweak for people who use USB audio devices, using the Windows own generic USB audio driver.
Increasing the buffer of the driver seems to have a great impact on sound for me using an Ayre QB-9 DAC. Sound seems soother, less grit. I'm using Windows 7 SP1 64bit, this will also Work for vista 32 and 64.

To set the registry entry:
Open Registry Editor. Locate and then right-click the following registry subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB\VID_<xxxx>&PID_<yyyy>&<??_??>\<look for ALL device instances with DeviceDesc:  USB Audio Device mentioned>\Device Parameters

in Device Parameter folder right click, DWORD (32-bit) Value. Rename to CapturePacketsPerUrb, and then press ENTER.

Right-click CapturePacketsPerUrb, and then click Modify.
In the Value data box, type in 10. 10 = 10ms buffer, you can choose between 3 - 10 ms. 10ms worked best for me.
you must restart your PC after adding this registry setting

Happy listening.

Thanks for this advice. Has really made a BIG difference for the better here. much cleaner and focused, and yes, less jittery sound. Am using an i3 intel 2 core cpu with hyper threading disabled and having 2 real cores to play with. I have my audio player, USB audio driver and USB composite driver all running on the same one core rather than being split over 2. the difference is HUGE.

Hi all,

if you can't wait there is a little tool (XP for free) which tries to set the maximum possible resolution of the default windows timer.

http://www.lucashale.com/timer-resolution

Good luck!

Thanks for this software link, The improvement on sound is quite large when listening for long periods of time. Having the OS time resolution operating at 0.5ms, seems to bring the music into focus, cleaner, with blacker background. This is my first post here, and have to say this site has been invaluable for advice and tweaks on the windows OS.
