FilmmakerIQ.com and RØDE Microphones are proud to give you a sneak peak at the first lesson in our six part course which will cover science/microphones, recording, editing, foley, and ADR. We are also hard at work behind the scenes updating the site to include even more interaction which should be live in the coming weeks. Until then - enjoy this lesson on the history of sound at the movies.

The inclusion of sound at the movies was one of the most dramatic changes in all of film history. Dive into the early experiments of Edison trying to incorporate sound from film's inception, through the experiments in the early 1920s, the Jazz Singer and the industry sound overhaul, and finally the multi-channel surround and modern movie sound technologies.

Researchers Turn Everyday Objects Into Visual Microphones

Abstract: "When sound hits an object, it causes small vibrations of the object’s surface. We show how, using only high-speed video of the object, we can extract those minute vibrations and partially recover the sound that produced them, allowing us to turn everyday objects — a glass of water, a potted plant, a box of tissues, or a bag of chips — into visual microphones. We recover sounds from highspeed footage of a variety of objects with different properties, and use both real and simulated data to examine some of the factors that affect our ability to visually recover sound. We evaluate the quality of recovered sounds using intelligibility and SNR metrics and provide input and recovered audio samples for direct comparison. We also explore how to leverage the rolling shutter in regular consumer cameras to recover audio from standard frame-rate videos, and use the spatial resolution of our method to visualize how sound-related vibrations vary over an object’s surface, which we can use to recover the vibration modes of an object ~ Project Webpage"

Where Not to Fly Multirotor UAV's

This map only applies to US laws and regulations. This map doesn't include all the areas where drones are banned. Also note this information would be equally applicable for any RC Aircraft and NOT only for multirotors or "drones" as they are called in the media.
