Eli5 How does music from a live band for example travel through wires and digital formats yet sound exactly the same when coming out of my headphones?
In: Technology
All that sound is is just a very complicated pressure wave: the air shaking back and forth in a set, complicated pattern.
If you have some method (a microphone) that can record those pressure waves, and then later use the recorded information to tell a speaker how to shake the air around it the resulting pressure wave will be interpreted by our ears and brains as the same sound.
