Welcome to Altona! One of my passions is digital audio signal processing and I am excited to announce the launch of this new website. Here I will list unique and innovative audio plugins that I have been experimenting with over the years. I hope you will find them useful. Please check out the first one, Tilt&Shelf, the audio industry’s first minimum-phase equalizer with continuously-variable slope and maximally-flat group delay.

I look forward to your comments and suggestions.
