      Airwave is a wine based VST bridge, that allows for the use of
      Windows 32- and 64-bit VST 2.4 audio plugins with Linux VST
      hosts. Due to the use of shared memory, only one extra copying
      is made for each data transfer. Airwave also uses the XEMBED
      protocol to correctly embed the plugin editor into the host
      window.
