Driving Miss Digital is a primer that explains, from first concepts, the basics and basis of modern audio and video technology. It is written as a fictional love story in simple English.
I highly recommend you read not more than two articles a day. You’ll have the answer to everything you’re looking for in no time. Enjoy!
