I'm looking for a program or plugin that will allow me to look at a waveform like you would with a real oscilloscope. I'd like to be able to zoom into a segment and see if that waveform changes. Currently I've found that Winamp's Tiny Fullscreen scope to be the best but there is no ability to zoom, and its fullscreen which is a minor problem. There is also "VS Oscilloscoop met VU Meter" plugin which is almost the same as the Tiny Fullscreen except its not full screen. It looks like: Both are decent for viewing the whole thing, but I'd like to be able to zoom in and watch in realtime. Any suggestions? Edit: Open Source and for linux/OS X is an option too. This is partially for a project we are on at work and partially for my own curiosity.
