Dexterpen is a stand-alone Windows graphics utility for those small repetitive tasks which take away valuable time from your working day. Use Dexterpen to create collections of drawings of slightly different components to import into your favorite CAD program, or as an EMF into WORD. You can also use Dexterpen to dynamically experiment with components without learning to learn program or buy an expensive parametric design program.

parametric (FFT) approach and the parametric (AR) approach. Use the Dynamic Noise Reduction option, to control the amount of hiss removal that will be performed, dependent on the volume and frequency content of the audio at any given point. DeNoise Plus FFT/AR - Now choose between two methods of spectrum estimation - the nonparametric (FFT) approach and the parametric (AR) approach. The new Noise Floor parameter lets you set a `crossover` volume
