There are several microphone patterns that determine the directionality of sound pickup. Omni-directional microphones pick up sound equally from all directions, making them good for interviews where mic angle is variable. Cardioid microphones are most sensitive to sound from the front and pick up less from the sides and back, reducing feedback and ambient noise. Bi-directional microphones pick up sound equally from the two sides but not the front or back. Mid-side stereo techniques use a bi-directional mic together with a cardioid mic to allow control over the left-right stereo image during mixing. Hypercardioid and shotgun microphones have a tight, directional pickup pattern that focuses on sound from directly in front

Classes Of Microphones
There are three main classes of microphones: dynamic, electret condenser, and true condenser. Dynamics have the least sensitivity and generate electricity from sound-induced movement within a magnetic field. Electret condensers require battery power and have greater sensitivity than dynamics. True condensers are the most sensitive and require external phantom power but are best for capturing subtle sounds. Microphone selection depends on the application and a balance of attributes like reach, sensitivity, pattern, and rejection of ambient noise and echoes.

Microphones
There are different types of microphones that work in various ways to convert sound waves into electrical signals. Moving coil microphones have a coil of wire wrapped around a magnet that induces a current when vibrations move the coil. Cardioid microphones only pick up sound from one direction, which can be useful in noisy environments. Different microphones such as the Shure SM58 and Beyerdynamic models have different polar patterns and uses such as live vocals, radio broadcasting, and music recording.
Microphones and its types

An Introduction to Microphone
Microphones are transducers that convert sound energy into electrical signals. There are two main types: dynamic and condenser microphones. Dynamic microphones have a simple design without needing power, making them durable for high volumes. Condenser microphones require power but produce stronger signals and are more sensitive, suited for subtle sounds. Microphone directionality depends on their polar pattern, being either omnidirectional, unidirectional, or bidirectional in capturing sound from different angles.
Polar patterns
This document discusses microphone polar patterns, which refer to how sensitive a microphone is to sound from different directions. The three main polar patterns covered are omnidirectional, bidirectional, and unidirectional. Omnidirectional microphones pick up sound equally from all directions, bidirectional microphones pick up sound from the front and back but reject the sides, and unidirectional microphones like cardioid, supercardioid, and hypercardioid primarily pick up sound from the front while rejecting sounds from other directions to varying degrees. The document provides examples of microphones with different polar patterns and tips on choosing a polar pattern based on the recording application and desired sound.
Basics of microphone
This document provides an overview of microphones, including their basic components and functions.

Working Principals of Microphones
Microphones work by converting sound wave vibrations into electrical signals. They have a light diaphragm that vibrates when hit by sound waves, causing a current to vary in the microphone. This signal is then sent to a mixer or amplifier. There are different types of microphones that use different conversion technologies like dynamic, condenser, or ribbon. Each type is suited to different applications.
Microphones an introduction
Microphones convert sound into electrical signals. There are three main types - dynamic, ribbon, and condenser - which differ in their transducer mechanism and power requirements. Dynamic microphones are robust and inexpensive but have limited high-frequency response. Ribbon microphones have a smoother frequency response than dynamics but require more care. Condenser microphones have the best high and low frequency response but require power and can be more expensive. The polar pattern determines a microphone's directional properties, with cardioid being most common due to feedback resistance for live sound reinforcement.

sound basic & microphone
Sound is a longitudinal wave that travels through a medium as a series of compressions and rarefactions. When sound waves reach the ear, they are converted into electrical signals that travel to the brain via auditory nerves. Microphones convert sound waves into electrical signals. Microphone placement depends on the sound source and microphone characteristics to capture sound with proper clarity, balance, and lack of feedback. The document discusses the nature of sound waves, microphone types and their uses, and considerations for microphone placement.
Type and applications of microphones
Microphones come in a variety of types defined by their transducer principle - how they transform acoustic signals into electrical signals. The main types are dynamic, ribbon, condenser, piezoelectric, and fiber optic. Microphone design also affects directivity - whether they are omnidirectional (non-directional) or unidirectional like cardioid, bi-directional, or shotgun. Additional factors are diaphragm size - small, medium, or large - and manufacturer, with common brands being Sennheiser, Shure, and Beyerdynamic. Microphones have wide applications from computers and phones to music recording and performance.

Lesson 15 polar curves
This document provides an overview of polar curves and coordinates. It defines polar coordinates, explains how to plot points in a polar coordinate system, and how to convert between polar and rectangular coordinates. Examples are given to plot points with polar coordinates and express rectangular coordinates in terms of polar coordinates. Finally, common polar curves such as the cardiod, limacon, roses, spirals, and lemniscate are listed.
Lesson 14 a - parametric equations
Parametric equations define a curve where x and y are defined in terms of a third variable called a parameter. The graph of parametric equations consists of all points (x,y) obtained by allowing the parameter to vary over its domain. Eliminating the parameter between the two equations yields a non-parametric equation of the curve. Examples are provided of eliminating parameters between various parametric equations to obtain the curve and sketching the resulting graphs. Exercises are given to further practice eliminating parameters and sketching curves.

Silhouette Photography Slideshow
1. A silhouette is an outline of an object with no internal details, usually appearing black against a brighter background due to backlighting from a light source like the sun.
2. To capture a silhouette, the object must be placed directly in front of the light source so it blocks the light. Too many light sources or a background that reflects light can wash out the silhouette effect.
3. Any object can be used for a silhouette as long as it can be backlit, like holding up a fish or photographing under a swimming fish to capture its silhouette against the sunlight filling the water.

Similar to Microphone Patterns
Microphones
Cardioid, super/hyper-cardioid, omnidirectional, figure-8, and shotgun microphones each have different polar patterns that determine how they capture sound. Cardioid microphones focus on sound directly in front while rejecting ambient noise from the sides. Super/hyper-cardioid microphones have an even narrower pickup pattern. Omnidirectional microphones capture sound from all angles but do not reject noise. Figure-8 microphones pick up sound from the front and back to provide stereo effect. Shotgun microphones focus directly on the sound source in front with high gain, recording other noises at low gain, making them well-suited for documentaries.

A transducer converts one form of energy to another without changing the signal. A microphone is a transducer that converts sound wave variations into voltage signal variations. There are three main classes of microphones: bidirectional which is equally sensitive from the front and back, unidirectional which is most sensitive from one direction, and omnidirectional which is equally sensitive from all directions. Microphone types also differ in their frequency response, polar pattern, and power requirements. The type chosen depends on the specific recording application and environment.
Sound unit 4
Sound is a vibration that propagates through a medium such as air or water. Humans can hear sounds between 20 Hz and 20 kHz. Dynamic microphones are commonly used for live performances as they are durable, while condenser microphones are commonly used in studios as they have better frequency response. Different types of microphones include lavalier, boundary, and cardioid microphones. Recording equipment includes digital audio workstations, handheld recorders, acoustic cameras, and screen recorders. Multi-track recording allows multiple sources to be recorded simultaneously.
Sound unit 4
Sound is a vibration that propagates through a medium such as air or water. Humans can hear sounds between 20 Hz and 20 kHz. Sound is measured in decibels and moves through vibrations and reflections off surfaces. Dynamic microphones are used for live performances as they are ruggedly built to handle loud noises. They work through electromagnetic induction of a diaphragm, coil, and magnet. Condenser microphones are used in studios as they have better frequency response but are more sensitive. Types of microphones include lavalier, boundary, and cardioid microphones. Recording equipment includes Logic Pro, handheld recorders, acoustic cameras, and screen recorders. Multi-track recording captures multiple sources simultaneously like during
MCB 49 CH7 AUDIO LECTURE
This document discusses sound and audio equipment used in film and television production. It provides information on different types of microphones like dynamic, condenser, and ribbon microphones; pickup patterns like omnidirectional, cardioid, and hypercardioid; windscreens and pop filters for protection; lavalier and handheld microphones for interviews; audio mixers and VU meters for controlling levels; and connectors. It also discusses aesthetic principles for sound like using it to establish context and continuity, and matching energy and mood. Finally, it provides recommendations for microphone usage during electronic news gathering.
Sound Advice from Jeanine Howard-Cherry
Sound enhances storytelling in three key ways:
1. It establishes the setting, mood, and unseen actions to transport the audience.
2. Music can gain attention, create mood, and establish location to direct the story.
3. Sound enhances but should not repeat visuals; writing should complement rather than conflict with sound effects and music.
Why you must calibrate your Audio Monitor speakers and how to do it
This document discusses how to properly calibrate monitorspeakers. It recommends aiming the speakers towards the listening position and setting an equal distance between the speakers and listener. The optimal speaker height is ear level. Room acoustics like early reflections and wall distance impact sound and should be addressed. Genelec products help correct issues from room interactions to achieve accurate sound reproduction.
Report task 2
The document summarizes different types of microphones and their uses. It describes dynamic microphones like the Shure SM54 that are durable for live performances. Condenser microphones require power and pick up more sound, making them better for studio use. Boundary microphones and shotguns are used for events like press conferences. Polar patterns determine the direction of sound detection, from omni to cardioid. Proper microphone placement and avoiding obstructions are important for clear sound. XLR and jack cables are used to connect microphones.
Tv sound..
Sound waves travel through air and are caused by vibrating objects. They have properties of frequency, amplitude, and phase. The human ear is most sensitive to mid-range frequencies and less so for high and low frequencies. There are different types of microphones including dynamic, condenser, and directional microphones that are used for different applications like interviews, field recording, and studio work.
Microphone basics
This document provides an introduction to basic microphone concepts, including:
- Microphones convert sound pressure variations into voltage variations. The main types are dynamic, condenser, and ribbon.
- Dynamic microphones use a diaphragm attached to a coil that moves in a magnetic field to produce a signal. Condenser microphones use a diaphragm that changes the distance between capacitor plates.
- Microphone characteristics include polar pattern (directionality), frequency response, and power requirements. Common polar patterns are cardioid, omnidirectional, and figure-8. Frequency response can be flat or tailored.
Music products final presentation
Microphones are transducers that detect sound signals and produce an electrical representation of sound. The most common microphones for music are dynamic, ribbon, or condenser microphones. Dynamic microphones work by using a coil of wire moving in a magnetic field to produce a voltage proportional to sound pressure. Ribbon microphones work by using a metallic ribbon moving in a magnetic field to produce a voltage proportional to sound velocity. Condenser microphones work by using a thin metallic membrane that changes spacing from a back plate in response to sound pressure changes.

Multitrack Workflow for Cinema/Video
This document discusses multi-track audio workflows for cinema and video production. It begins by outlining the evolution from monaural to two-track to four-track recording. For two-track recording, it describes using one track for a live mix and the other for iso tracks or effects, or splitting mics between tracks. For four-track recording, it discusses options like recording iso tracks or a live mix plus iso tracks. It also covers techniques for 8+ track recordings like recording iso tracks and an attenuated dual mono mixdown. The document provides guidance on mic selection, placement, and track assignments.

Calling for the Roll
The document provides instructions for the process of calling the roll at the beginning of a film or video shoot. It describes the steps taken by the assistant director, sound mixer, camera operator, and clapper/loader. These include putting the set on a light and bell, rolling sound or video, slating the scene and take number, recording room tone, marking the clapstick, and calling action. The goal is to synchronize footage and audio while providing scene identification for editing.
Welcome
This document introduces the importance of sound in movies from early silent films to modern productions. It discusses the transition to "talking pictures" and how dialogue is now a key part of film scripts and storytelling, as the soundtrack alone can convey much of the plot without video. Production sound is crucial for recording live dialogue on set.
Microphone Types
The document discusses different types of microphones and their common applications. It describes microphones used for podiums and desktop recording that are dynamic and prevent feedback. It also mentions lavalier microphones that are small and body-worn, as well as pressure zone microphones that are mounted above a hard surface to pick up sound hemispherically from several feet away. Studio music microphones are highlighted as high quality condenser microphones suitable for rich sound recording but too sensitive for live performance.
Priorities Of Recording
The document outlines six priorities for a production mixer when recording audio on set: 1) Getting usable dialogue is the top priority. 2) Maintaining proper audio perspective to match the camera viewpoint. 3) Syncing sound effects without compromising dialogue. 4) Recording wild lines and off-camera dialogue for coverage. 5) Capturing wild sound effects not available in libraries. 6) Recording ambiance and room tone to patch holes in the edited soundtrack.
The Professional Approach
This document provides guidance for sound crew roles and responsibilities on film productions. It discusses the roles of the production mixer, boom operator, and utility sound technician. It covers salaries, equipment needs, budgets, and best practices for professional and effective sound capture and management. The key roles, responsibilities, and priorities are to hire the right crew, properly prepare equipment, capture all dialogue, and maintain a professional attitude and efficient workflow.
What Is Production Sound?
Production sound is the complex craft of recording live dialogue and sound effects on set during filming. It requires a blend of creative judgement and technical expertise to deal with challenges like noise problems, equipment failures, and changes in blocking or performance. The production sound mixer fills several roles, operating audio equipment while also serving as a sound editor, director, and member of the filmmaking team.
Why Learn Production Sound?
Production sound is an essential element of filmmaking that provides more employment opportunities and a higher position in the crew hierarchy than other jobs like camera, editing, or production assistant. Learning production sound helps directors understand crew capabilities to effectively communicate priorities and evaluate audio quality, and it helps those in the film industry understand sound crew roles to work as a successful team.
