What's New

Version 1.0.9:
  • The Limiter doesn't distort the sound anymore but always caps it to the threshold (so it will never be too loud no matter what you do), which now can go down to -30 dB, while preserving the dynamics and the quality of the sound./li>


  • Mac OS X 10.4 or later
  • A VST/AudioUnits compatible host.
