Integrated Systems Europe 2024 - What Does It Mean for the Audio Industry?

I returned from Barcelona, Spain, after five exhausting days, which were not easy for anyone in the audio industry who was forced to fly from the NAMM Show in Anaheim, CA directly to Europe. I wrote this First Impressions ISE 2024 report in an effort to summarize this extremely well organized and successful event - celebrating the show's 20th anniversary. I discuss what is sustaining this systems integration event that everyone understands as many different things, and what does it means for the audio industry.
