New SDR# Audio Waterfall Plugin

The old audio waterfall plugin for SDR# seems to be no longer available for download anywhere (it may have gone out of date and is no longer compatible with the latest versions of SDR#). Alan Duffy decided to write his own version of the audio waterfall plugin and make it available for download. An audio waterfall shows the demodulated audio in waterfall form, essentially creating an audio spectrum analyzer. This can be useful for understanding the demodulated frequency structure of a signal.

To install the plugin simply download the dll from his website and place it in the SDR# folder. Note that for us Chrome detected this file as malicious, but this is a false alarm as Chrome does this often with unknown .dll files. To recover the file we had to go to the Chrome menu -> Downloads, then select “Recover File” to download the file. (If you still have problems with the download then check out the comments as some users have kindly mirrored it). Then open plugins.xml file with a text editor, and add the magicline specified on his page.

    This is cool. I sure with they’d make a plugin that can decode DMR, DStar, P25, etc. Yes I know there is DSD but it would be nice to have it all self contained. And some kind of Trunking plugin would be cool.

    it would be nice if you could download this DLL… the site its hosted on is being blocked by chrome (and even blocking the file if you bypass the warnings)..
