On 2 June 1948, the Professional Group on Audio of the IRE was formed, establishing what would become the IEEE society structure we know today. 75 years later, this group - now the IEEE Signal Processing Society - is the technical home to nearly 20,000 passionate, dedicated professionals and a bastion of innovation, collaboration, and leadership.
