Abstract

In little more than a hundred years, we’ve gone from wax cylinders to streaming services, and brass horns to stereo earbuds.  It’s been a journey that’s seen constant battles between manufacturers, recording studios and audiophiles, as they’ve grappled with technology, audio quality and convenience.  In this talk, Nick looks at how our desire to listen to music has created a multi-million dollar industry which has created its own mythology about audio quality.  It’s a history of surprising and often accidental development that has always been difficult to predict, but which is still trying to find new ways to make more money from our ears.  Come and hear how we got to where we are today and where we may be going in the future.
