A "larger" in time oscilloscope
I want my oscilloscope to display the audio information from 1 or 2 seconds ago, or even more. I don't know what I'm doing wrong... It works a little bit, but there are errors. Could you help me?

You'll need to store the information yourself in megabuf. But there is no continuity guarantee in AVS.

Take a look at the avs, because that's exactly what I'm doing, I'm storing the information in megabuf. But it doesn't work as it should, there is no continuity, because of me OR because of the megabuf??

Yes and No... I'm just trying to do a simple superscope. But something like you did, to be able to see the audio data from the actual moment back to a few seconds. To make you understand better, I'll tell you what I need it for: i am ocassionally using winamp as an oscilloscope (a real one) with help from the linein input. And if, for example I input a 50Hz sine, I can only see aboute half a sine on the screen, due to the size of the default buffer... i think. Hope you understand.

AVS always gives you the last available time samples. How often this is updated depends on the frames per second, so you have no way of ensuring continuity, save for doing cross correlations or something (expensive!).

So what you want is hardrealtime. AVS is the softiest softrealtime that I know of.

Why don't you simply create a little tool for that in VB or something like that? on the other hand, there must be several tools just for that available over the internet.

Google is your friend.
