This document contains a lecture on production audio and sound. It includes links to various videos about microphones, acoustic properties of rooms, double system recording, wind noise reduction, foley, sound design, and post production audio techniques. The document covers topics such as microphone types and their uses, polar patterns, dynamic range, signal to noise ratio, diegetic and non-diegetic sound, and how sound interacts with different surfaces.

- 8. Sound Sound waves are vibrations. Microphones convert vibrations to electrical signals. Receivers and speakers convert electrical signals to vibrations. Vibrations are sound waves.
- 13. Sound Acoustics When sound hits a • Hard surface (plastic, glass, tile, stone, metal) more sound is REFLECTED – higher frequencies are reinforced – sound is brighter and sharper. LIVE • Sounds bounce back. The larger the space, the greater the reverberation.
- 14. Sound Acoustics When sound hits a • Soft surface (curtains, couches, rugs) more sound is ABSORBED, in particular higher frequencies – sound is more mellow, even dull or muted. DEAD
- 15. Sound Acoustics Surroundings are too “live” • Move mic closer to subject • Pull curtains or drape blankets • Add thick rugs or cushions • Use upholstered furniture • Add acoustic panels
- 16. Sound Acoustics Surroundings are too “dead” •Move mic further from subject •Open curtains, increase hard surface space •Remove rugs or cushions •Remove upholstered furniture and use un- upholstered furniture •Add board, plastic, floor panels •Add artificial reverberation (reverb) in post

- 24. Sound Microphones – Dynamic (Handheld) • Rugged workhorses • Resist distortion from loud sounds • Decent sound quality • No electrical power required
- 25. Sound Microphones – Condenser • Produces very high audio quality • Can be small • Needs battery or phantom electrical power • Examples – shotgun, lavalier, miniature.

- 44. Sound Dynamic Range Noun: The range of acceptable or possible volumes of sound occurring in the course of a piece of music or a performance. The ratio of the largest to the smallest intensity of sound that can be reliably transmitted or reproduced by a particular sound system, measured in decibels Audio Level / Gain / Amplification – Exposure Dynamic Range – Exposure Latitude Automatic Gain – Automatic Exposure High Volume Distortion – Overexposure Low Volume Noise - Underexposure
