I also have the latency bug in both versions. I am running Windows Vista on a 3.0 GHz Core 2 Duo with a Realtek HD audio driver.

Thanks for reporting that, sasuke. I'm waiting for nula's post, maybe you have something in common in yours PCs configuration, maybe I can tell where the latency error comes from.

Well, I tested DefleMask on a Realtek HD audio card (on Windows XP) and the tracker works right. Seems to be a Windows Vista Audio Driver issue.

Considering you tested on Windows XP, this does make sense. Vista/7 handles audio differently than XP, especially when using DirectSound.

I found a wikipedia article that confirms this, if it helps: http://en.wikipedia.org/wiki/DirectSound#Windows_Vista

Before launching DefleMask public Beta, I tested DefleMask on a Toshiba Satellite running Windows 7; and works just right. It's not a OS compatibility bug appears like.

I tested DefleMask on all the PCs that I could (Windows XP/Windows 7, different Audio Cards and Differents processors [Atom, Core 2 Duo, Pentium 4)] and it works fine in all, without delay, so I can not really do the necessary tests to find out what's the problem. Seems to be a very specific issue.

Thanks. Sasuke also have the delay problem under Vista with a Realtek HD Audio. So, Realtek's Vista drivers seems to be the problem. Under XP with a Realtek HD Audio DefleMask works without delay, maybe updating your soundcard drivers would solve the problem.

I added a sampling rate selector to DefleMask: 22kHz, 32kHz and 48kHz <-default value used on Beta 1.
I think that using 32kHz on yours Realtek HD Audio cards would solve the problem, and the audible differences using 48kHz and 32kHz are minimal (I cannot say that for 22kHz :D).

When beta 2 is released, I hope that you can enjoy DefleMask on your systems.  :)

Hi, sorry but the problem persists. I can hear how sampling rate change is applied but sound drops continue in same intervals. Only positive thing is that Vista is almost dead system now :D

Oh, that's bad. :(
Then maybe is the Buffer's size. But the really bad thing about this is that I can't really make tests to see if I can solve this latency problem, I doesn't have a PC with Vista and a Realtek HD Audio card.

Maybe you could just compile version for me which would have latency set to 150ms for example. Then we would know for sure if it's this problem and then you could just add latency fader in the Deflemask settings for people with similar problem like mine...

Yeah, that would be a good idea, but there's no a latency value on DefleMask because the way in wich the output is generated is not dynamic. In other words, the emulator will play only precompiled commands, so, it simply starts to play the full tune like a mp3 player.

However, I'm almost sure that the problem is generated by the DefleMask's buffer size. I'm trying to make it selectable. :D

Hey Delek!

First off, nice work! I just heard about this today and thought I would give it a go.

I downloaded the latest Beta 3 and I too am having latency issues. :/ I am running Vista on a Dell Inspiron 1545 and this is the only tracker/audio application I seem to have trouble with. Here's a quick clip of the "awesome" song file included with the download:

Just a heads up!

Yes, unfortunately, there's some problems with some Vista audio drivers/soundcards and DefleMask's YMU759 emulator; however, on Windows 7 this issue appears to be solved, this is a problem of Windows Vista audio appears like.

Do you have Windows 7 installed too?, if so, could you please test if the latency bug is still there?, thanks.
