title: Apply VST audio effect/plugin to audio-file
body: <p>This is my first question after leeching over here for some time.. So spare me.</p>
  
  <p>I need to apply the iZotope Vinyl VST effect to some audio files via CLI or C++ (so language doesn't really matter), it has to work on a Mac or on a Unix based system. I've researched all over the webs and can't find any working solution.</p>
  
  <p>I've tried using MissWatson, a command line utility, this works but my result audio files are silent... </p>
  
  <p><code>./MissWatson -plugin=Vinyl -input-file="/Users/Sjaq/Desktop/test.wav" -output-file="/Users/Sjaq/Downloads/MissWatson-v1.0-mac/res.wav" -parameter=1:0.6,2:0.6,11:0.4</code></p>
  
  <p>Then I tried using the <a href="http://www.steinberg.net/nc/en/company/developer" rel="noreferrer">Steinberg VST SDK</a> by creating a host application, starting from the vstvalidator provided by the SDK. But when I try to load the VST I get this error: </p>
  
  <p><code>2010-12-01 16:57:40.774 vstvalidator[4654:903] Error loading /Library/Audio/Plug-Ins/VST/Vinyl.vst/Contents/MacOS/Vinyl:  dlopen(/Library/Audio/Plug-Ins/VST/Vinyl.vst/Contents/MacOS/Vinyl, 262): no suitable image found.  Did find:
   /Library/Audio/Plug-Ins/VST/Vinyl.vst/Contents/MacOS/Vinyl: no matching architecture in universal wrapper
  </code> </p>
  
  <p>And I don't know what to do. I'm pretty new to C++ and and made a few apps without any issues, but this time I've hit a dead end.</p>
  
  <p>I've read about pyvst but it seems to need a DLL for the VST so that didn't work either.</p>
