Great post by recording engineer Justin Colletti on SonicScoop.com. In it he lists nearly thirty free software plugins for digital audio workstations using a version of Avid’s Pro Tools. The article names plugins in these categories: equalization, filters, sound shapers, reverbs, delays, amplifiers, samples, instruments, meters, and master faders. The author expects to update the list based on both reader comments and industry changes.
