#17: Software Engineer Drew Shapiro—Understanding the Technology of Sound (Part 1)
Manage episode 273852817 series 2776888
This episode can be summed up with two competing quotes:
“Any sufficiently advanced technology is indistinguishable from magic.”
"Any sufficiently analyzed magic is indistinguishable from science!”
The first quote is by the famous science-fiction writer Arthur C. Clarke. The second quote is unknown, but points out that the spell books for such magic are to be found in the methods and tools of science.
So how does sound work? What is the difference between analog and digital audio? How does a computer store an audio file and then rebuild it into sound waves that you can hear? What is the journey that this podcast took to get from our voice boxes into your headphones?
We answer those questions and more in this episode all about the technology of sound with software engineer Drew Shapiro. While studying electrical engineering and computer science at MIT, Drew also had a minor in music, making him a perfect guest for this episode.
This episode is the first half of our conversation, with Part 2 dropping in a few days. Enjoy!
