I’ve tried this DSP plugin in its many guises over the years with varying results.
However it is used by lots of people who use RadioDJ.
How do you install Stereo tool in RDJ?
1) Install the DSP Stacker plugin for RadioDJ
2) Download the latest Winamp DSP version of Sterotool
3) Run the installer and browse to the RadioDJ plugins folder. (e.g C:\RadioDJ\Plugins) remove the Winamp folder part.
4) Click on Install, ignore this warning and click yes.
If all has gone to plan the dsp_stereo_tool.dll should now be in your plugins directory.
5) Start RadioDJ go to Options and click the plugins button. Highlight the DSP plugin and click on show.
Highlight the stereo tool DSP in the top list and click the green + to add it to the list of DSP’s you wish to use. Double click on the plugin and the stereotool plugin should now be visible.
Please note: Support for the RadioDJ DSP stacker plugin is somewhat limited. You can ask on the RadioDJ forums but you aren’t guaranteed to get help.
