Viagra by mail Without telling anyone, viagra by mail Adobe changed the Sound API on the recent released Flash Player 10. Viagra by mail When we released our AudioTool yesterday we encountered a ridiculous long latency of almost one second. Viagra by mail The latency time is the time between computation of the sound and the point where you can listen to the actual sound. Viagra by mail It is important to keep this value low for live experience. Viagra by mail After hours of research some people figure out, viagra by mail that the amount of samples you pass to the sound card is changing the latency dynamically BUT will never decrease. Viagra by mail If you once pass a higher number of samples you cannot go back easily.
Viagra by mail Here is how we handled sound creation before in the AudioTool
We simply passed 2048 samples (minimum amount) every time the SampleCallbackEvent was fired. Viagra by mail The playback was stable - even when scrolling the desktop with a lot of devices. Viagra by mail For processes that would block the CPU for some time (e.g. Viagra by mail create new plugin instances), viagra by mail we passed 8192 sample (maximum amount) to remain stable playback and execute the processes after. Viagra by mail So we dynamically increased the latency once to have more space for heavy computation. Viagra by mail Afterward we went back to normal (2048 samples). Viagra by mail In fact this worked great!
Viagra by mail The Release Player changed all that
With the latest player, viagra by mail every time you increase the number of samples you will increase the overall latency. Viagra by mail And there is no way of decreasing it again without stopping the SoundChannel. Viagra by mail So now we just pass 3072 samples (~160ms latency) all the time. Viagra by mail Meaning that critical processes won't be caught and will cause gaps in playback.
Viagra by mail Again we now have 4 times more latency, viagra by mail but playback is overall less stable.
Viagra by mail The worst thing is, viagra by mail that nobody told us and I am still not sure, viagra by mail what that is all about. Viagra by mail The new sound feature was great and worked great for all release candidates. Viagra by mail And all the sudden they changed it - again - without telling anyone. Viagra by mail If we had this information before, viagra by mail it would not have been so hard to accept it. Viagra by mail And of course we may have found some workarounds.

I truely hope this is a bug regression of some sort, but it’s unfortunate that it got introduced to the release version like this. Please do post when you’ve filed a bug report, and I’ll go in there and vote it up as well.

Ouch, that’s no good, thanks for the heads up!

Sad sad sad.
I’m also quite pissed off about the FileOpen dialog “security” measures that breaks existing Flash9 applications.
Looks like Adobe turned what was a nice update of the player into a big headache for us developers…

This is really sad. I hope for soon Adobe react and change things back, if they was better before. Guys, you done reat work and Adobe should take this in account. I hope for good end.

Part of this may be explained by this paragraph from Tinic’s original ‘Adobe Is Making Some Noise Part 2′ post:
“There is an internal buffer in the Flash Player which is about 0.2 to 0.5 seconds depending on the platform which is preventing drop outs. It will automatically be increased if drop outs occur. This internal buffer is the key for the high latency I was alluding to earlier. You should never depend on a certain latency with this API in your application. To enforce this there is a slight random factor in choosing this buffer size when the Flash Player launches.”
