MashTactic
    
  Mashup tool
  * 8 stereo areas of sharp cut-off filtering.
  * Adjust levels separately in all selected zones.
  * Vocals and other sounds can be identified and manipulated within a 
    full mix.
  * Allows the user to emphasise or cut percussive transients giving 
    control over punch or softness in any zone.
  * Each zone can pan separately.
  * Great for analysing balance and frequency mix of a track you're 
    composing.

  What is it?
  MashTactic was initially designed as a mashup tool. It can separate 
  different parts of a full mix, manipulating different frequencies and 
  stereo location. Up to eight zones can be created that can then be 
  panned, emphasised or cut out completely. It can be viewed as an eight 
  band filter that exists in stereo ranges as well as frequency.

  Transients of varying length can be separated from constant sounds, 
  which allows the user to manipulate the initial punch of percussion, 
  either by emphasising or softening the attack, this can be done 
  separately in any of the eight zones.

  What it is not?
  There are no harmonic analysers in MashTactic. It's all achieved 
  through stereo balance analysis and very sharp filtering. Some mixes 
  won't be pulled apart that easily, but the 8 filter patches turn out 
  to be very useful at cutting unwanted parts of a mix. Also harmonic 
  analysis tends to require large amounts of user interaction, and this 
  often creates clear but broken vocals with unsteady timelines
