Multimedia Object - Audio
The document discusses MPEG audio compression standards. It provides details on MPEG-1 audio layers including:
- MPEG-1 audio layers 1, 2, and 3 have increasing complexity and performance with layers 1 being the simplest and layers 3 providing the best quality.
- All layers use a filterbank and quantization while layer 3 adds an MDCT transform and improved quantization.
- Layers are decoded using frame unpacking, reconstruction, and inverse mapping processes.
- Frames contain header, allocation, and sample data with headers being more error resistant.
Audio
Digital audio can be in the form of sampled audio or MIDI data. Sampled audio involves capturing an analog sound wave through sampling at regular intervals (sample rate) and storing the amplitude measurements digitally. MIDI data instead stores instructions on how to recreate a musical performance without the actual sound recording. While sampled audio provides higher quality sound, MIDI files are smaller in size and can be changed without affecting pitch or quality, making them suitable for early web embedding. Factors like file format, playback capabilities and sound type must be considered when adding audio to multimedia projects.
Multimedia tools (sound)
Sound is created by vibrations that travel as waves through air or another medium. These sound waves can be captured and converted into digital audio files through a process called digitization. The quality of a digital audio file depends on factors like the sampling rate, which is the number of times per second the sound wave is measured, and the sample size or bit depth, which determines how finely variations in the amplitude of the sound wave are recorded. Higher sampling rates and more bits per sample result in better quality recordings but larger file sizes.
Digital audio formats
This document discusses digital audio media and production. It explains that all sound exists as analog waves that are sampled and converted to digital format for computer processing. Common digital audio formats are described, including uncompressed formats for high quality archiving and compressed formats like MP3 for distribution. Digital music software and services allow users to organize, playback, and distribute digital music collections on various devices. Suggestions are provided to improve an IT course by changing homework due dates and times.

Stereo uses two channels for left and right speakers, while surround sound uses additional channels for more speakers to enrich the sound experience. Dolby processing has evolved through several steps to provide lossless multi-channel surround sound with 8 or more channels. THX is not a recording or coding technology but a quality standard and certification system used primarily for movie theaters. The most common home surround sound layout today uses 5.1 channels, with two front speakers, two rear speakers, one center speaker, and a subwoofer for low frequencies.

Public Address System
The document provides information about public address (PA) systems, including:
- A PA system consists of microphones, mixers, amplifiers and loudspeakers to allow a person to address a large audience. It can also include prerecorded music.
- Microphones capture sound and convert it to an electrical signal. Mixers combine different audio signals. Amplifiers increase the power of the signal to drive speakers. Loudspeakers convert the electrical signal back into sound.
- Setting up a basic PA system involves choosing these core components - microphones, mixer, power amplifier, and speakers - as well as optionally adding a monitor system and signal processing like reverb and compression.
Audio systems
A basic sound system consists of an input device (microphone), a control device (mixer), an amplification device (power amplifier), and an output device (loudspeaker).
The primary goal of the sound system in sound applications is to deliver clear, intelligible speech, and, usually, high-quality musical sound.

This document provides definitions for various terms related to sound design and production. It includes a glossary with definitions for terms like foley artistry, sound libraries, uncompressed audio file formats like .wav and .aiff, compressed formats like .mp3, components like sound processor units and digital signal processors, audio formats like mono, stereo and surround sound, recording methods like analog and digital, and storage systems like compact discs. For each term, the student provided an internet definition and link and described how the term relates to their own production practice, such as using sound libraries to store sound files and .mp3 to save songs on their computer.
Loudspeaker-Types, designs, Application & Crossover
A loudspeaker is an electro acoustic transducer; a device which converts an electrical audio signal into a corresponding sound. (Electrical energy to acoustical energy)
Audio spot light
Audio spotlighting uses ultrasonic energy to create extremely narrow beams of sound similar to flashlight beams. It was invented in the 1970s and made commercially available in 2000. Audio spotlighting works by taking an original audio signal, modulating it with ultrasonic frequencies, and emitting it from an array of transducers. This allows the sound to be focused into a narrow, directed beam. Key components include a sound processor, frequency oscillator, modulator, and transducer. It has applications in areas like museums and ships where directable sound is useful. Advantages are directionality, no need for large speakers, and ability for nearby people to hear different sounds. Limitations include need for line of sight and inability to transmit over long
Production arts 2
The sound desk controls all audio equipment used on stage, including 24 channels to control microphones and speakers. It has a master volume to control all sound and panning dials to direct sound to left or right speakers. Different cables like XLR, jack, and phono are used to connect audio sources like phones, computers and instruments to the sound desk. Active speakers have built-in amplifiers while passive speakers require an external amplifier.
Production arts 2
The sound desk controls all audio equipment used on stage, including microphones and speakers. It has 24 channels that can adjust various properties of the sound like volume, panning, frequency levels. Active speakers contain their own built-in amplifiers, making them more portable than passive speakers which require an external amplifier. Various cables like XLR, jack, and phono cables are used to connect audio sources and equipment like microphones, speakers, and music players to the sound desk.

Music centre
- 2. A music centre (or center) is a type of integrated audio system for home use, used to play from a variety of media. The term is usually used for lower end or sub-high fidelity or hi fi equipment. The term itself has been in use since the 1970s, though in more recent times the terms mini, micro or midi hi-fi, or integrated hi-fi have been preferred. The distinguishing feature compared to high-end equipment is that there is usually only one main unit, with maybe a pair of detachable or separate loudspeakers, though some equipment also has these built into the main unit.
- 4. MUSIC CENTRE PART’S 1. RADIO TUNER 2. TAPE 3. CD PLAYER
- 5. 1. RADIO TUNER A tuner is a subsystem that receives radio frequency (RF) transmissions like radio broadcasts and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing usually because a lower frequency is used on the output. 2. TAPE commonly called cassette tape, audio cassette, or simply tape, is a magnetic tape recording format for audio recording and playback. 3. CD PLAYER CD player is an electronic device that plays audio compact discs.
- 7. pre-amplifier A pre-amplifier (preamp) is an electronic amplifier that prepares a small electrical signal for further amplification or processing. A preamplifier is often placed close to the sensor to reduce the effects of noise and interference. Power-amplifier a relative term with respect to the amount of power delivered to the load and/or sourced by the supply circuit
