Digital Audio

(2.0)

Introduction

(2.1)

Digital audio uses digital signals for sound reproduction. This includes analogue-to-

digital conversion, digital-to-analogue conversion, storage, and transmission. Digital

audio has emerged because of its usefulness in the recording, manipulation, mass-

production and distribution of sound. Modern distribution of music across the Internet

through on-line stores depends on digital recording and digital compression

algorithms. Distribution of audio as data files rather than as physical objects has

significantly reduced costs of distribution. (1)

Audio Hardware

(2.2)

As audio advances, more and more hardware becomes available for it. In recent years,

audio players have become increasingly popular with the general population. These

audio players include: Flash-Based Players, Hard-Drive Based Players and MP3 CD

Players.

Flash-based Players

Fig 1. MP3 Fig 2. Ipod

These are solid-state devices that hold digital audio files on internal or external media,

such as memory cards. Due to technological limitations, these are relatively low-

storage devices, commercially ranging from 128MB to 8GB, such as the second-

generation iPod nano, the SanDisk Sansa series of players. (2)

Hard-Drive Based Players

Hard Drive-based Players or Digital Jukeboxes aredevices that read digital audiofiles from a hard drive. These players have higher capacities, ranging from 1.5GB

to 160GB, depending on the hard drive technology. (2)

MP3 CD Player devices are that can play audio files from a CD-ROM in addition to

audio CDs. It uses a lossy compression algorithm that is designed to greatly reduce theamount of data required to represent the audio recording, yet still sound like a faithful

reproduction of the original uncompressed audio to most listeners.(2)

Recorders

(2.3)

Microphone (Mic)

The microphone is a device used for recording different types of audio. This devicehas become increasingly popular in recent years, as it makes recording and editing

easier.

Audio Editing(2.4)

In recent years, with the growing popularity of GNU/Linux, a number of Open Source

software projects have sprung up in order to develop an open source audio editing

program. This movement has been bolstered recently by the development of ALSA,

and the Linux low latency kernel patch, which allow the GNU/Linux Operating

System to achieve audio processing performance equal to that of commercial operating

systems. The multi-platform package Audacity is currently the most fully featured free

software audio editor. (5) Other editing software include Quickaudio, Goldwave,

Soundbooth and Wavesurfer.

Production(2.5)

With the advancements within the Digital Audio world, production in this field has

never been more popular, with the development of Podcasting and Studio Sound, etc.

It is becoming easier for the average person to create and access such material, and itwill only grow stronger as time continues.

Delivery(2.6)

Optical Disk

Fig 7. Optical Disk

In computing, sound reproduction, and video, an optical disc is a flat, circular, usually

polycarbonate disc whereon data is stored in the form of pits (or bumps) within a flat

surface, usually along a single spiral groove that covers the entire recorded surface of

the disc. This data is generally accessed when a special material on the disc (often

aluminium) is illuminated with a laser diode. (1)

InternetAs the Internets community increases, more and more people are using it to transfer,

record and edit their audio. At the present day, the Internet is the most effective way to

transfer audio.

BroadbandBroadband in telecommunications is a term, which refers to a signalling method,

which includes or handles a relatively wide range of frequencies, which may be

divided into channels, or frequency bins. The wider the bandwidth, greater is the

information carrying capacity. In radio, for example, a very narrow-band signal will

carry Morse code; a broader band will carry speech; a still broader band is required tocarry music without losing the high audio frequencies required for realistic sound

reproduction.

Flash Memory

9/19

Flash memory is non-volatile computer memory that can be electrically erased and

reprogrammed. It is a technology that is primarily used in memory cards, USB flash

drives (thumb drives, handy drive, memory stick, flash stick, jump drive), which are

used for general storage and transfer of data between computers and other digital

products. Examples of applications include PDAs and laptop computers, digital audio

players, digital cameras and mobile phones. (3)

File Types(2.7)

There are a handful of audio file types you should be familiar with if you are planning

to copy music off the Internet or even copy a CD. (1)

Waveform Audio (.wav)

MPEG-1 Audio Layer 3 (.mp3)

Windows Media Audio (.wma)

Benefits(2.8)

As digital audio players have spread, new uses have been found for them. This

includes podcasting, which are radio-like programs, or even TV-like video feeds, are

automatically downloaded into the device to be played at the owners convenience. As

the years progress, it is becoming easier to effectively use digital audio to our

advantage. (1)

Future(2.9)

New digital audio services like satellite radio, online radio, HD radio, and podcasting

with new subscription and data service business models are changing the way

consumers listen to radio. All four digital audio markets will grow steadily by 2010,

20.1 million households will listen to satellite radio and 12.3 million households will

synchronize podcasts to their MP3 players. Broadcasters and music labels must learn

to deal with this new, fragmented audience. The keys to success will be subscriptions,

ad targeting, and monetizing the many ways that digital audio will be consumed. (4)

Digital Video(3.0)

Introduction(3.1)Digital video is a type of video recording system that works by using a digital, rather

than analog, representation of the video signal. This generic term is not to be confused

with the name DV, which is a specific type of digital video targeted at the consumer

market. Digital video is most often recorded on tape, and then distributed on optical

discs, usually DVDs. There are exceptions, such as camcorders that record directly to

DVDs, Digital8 camcorders which encode digital video on conventional analog tapes,

and other high-end camcorders which record digital video on hard disks or flash

memory. (4)

Applications(3.2)

Digital video is more easily manipulated than analogue video. Digital video can be

duplicated without loss of quality, which is important for editing applications. The

ability to easily store and transmit digital video. The low bandwidth requirements of

digital video also makes it easy to store and digital video can be stored on compact

disc. (1)

Analog tape formats

Analog tapes are often referred to as a dead technology as Digital tape and Optical

disc continue to increase in popularity. Although still popular for home recording, the

VHS tape has largely been replaced by DVD for pre-recorded home video content.

Optical disc storage formats

DVD (Digital Versatile Disc or Digital Video Disc) is a popular optical discstorage media format that can be used for data storage, including movies with high

11

video and audio quality. DVDs are modelled in size after the compact disc (i.e.

diameter: 120 mm or 4.72 in, occasionally 80 mm or 3.15 in.); both are optical storage

media so similar that a DVD reader or writer can usually read CDs, but DVDs are

encoded in a different format of much greater density, allowing a data storage capacity

8 times greater. (3)

HD DVD, or High-Definition DVD is a high-density optical disc format designed for

the storage of data and high-definition video. HD DVD has a single-layer capacity of

15 GB and a dual-layer capacity of 30 GB; the HD DVD-RAM has a single-layer

capacity of 20 GB and a dual-layer capacity ofUndecided. (3)

A Blu-ray Disc is a high-density optical disc format for the storage of digital media,

including high-definition videoBecause of its shorter wavelength (405 nm),

substantially more data can be stored on a Blu-ray Disc than on the DVD format,which uses a red, 650 nm laser. A single layer Blu-ray Disc can store 25 gigabytes

(GB), over five times the size of a single layer DVD at 4.7 GB. A dual layer Blu-ray

Disc can store 50 GB, almost 6 times the size of a dual layer DVD at 8.5 GB. (3)

Software(3.5)

After Effects 7

After Effects uses a system of layers organized on a timeline to create composites fromstill images and motion footage, such as video files. Properties such as position and

opacity can be controlled independently for each layer, and each layer can have effects

applied. After Effects is often described as the Photoshop of video, because its

flexibility allows compositors to alter video in any way they see fit, as Photoshop does

for images. (2)

Premiere Pro 2Adobe Premiere Pro, formerly known as Adobe Premiere, is a real-time, timeline

based video editing software application. It is part of the Adobe Creative Suite, a suite

of graphic design, video editing, and web development applications made by Adobe

Systems.

Benefits(3.6)

Analogue video recording is a mature technology and has almost reached limits

determined by the laws of physics. Digital video technology has the potential to

achieve much higher levels of quality and the technology is being improved at anincreasing rate. But digital video does more than provide better pictures than analogue.

It has a number of unique properties that make possible applications that could not be

realised using analogue video. Firstly, digital video can be manipulated more easily

than analogue video. In addition to this, digital video can be stored on random access

media, whereas analogue video is generally stored sequentially on magnetic tape. This

random access allows for interactivity, since individual video frames are addressable

and can be accessed quickly. Finally, video in digital form can be transmitted across

channels unavailable to analogue video. The applications unique to digital video rely,

to varying degrees, on these properties. (1)

Future(3.7)

As the popularity for digital video increases, so will the technology for it. Exciting

new applications become possible when video becomes part of products, which in the

past, have been unable to incorporate video systems. The applications for video go far

beyond mere playback of existing content. With advanced processing technology, not

only is a higher quality user experience possible, so is a whole new range of

innovative applications where the device itself is able to intelligently use video to

improve quality of service, operating reliability and user safety. Consider a whole new

world enabled by digital video technology.

Digital Photography(4.0)

Introduction(4.1)

Digital Photography, as opposed to film photography, uses electronic devices to record

and capture the image as binary data. This facilitates storage and editing of the images

on personal computers, and also the ability to show and delete unsuccessful images

immediately on the camera or software itself. Digital cameras now outsell film

cameras and include features that are not found in film cameras such as the ability to

shoot video and record audio. Some other devices, such as mobile phones, includedigital photography features. (1)

Digital Photography Hardware(4.2)

For several decades, the film cameras dominated the photography market, the ability

to simply take photos with the camera and take them to a film developer became an

everyday thing. Although in recent years, film cameras have become less popular as

the digital camera took its place, as well as cameras being installed within most

common mobile phones. (1)

A large variety of data storage device formats are used in consumer digital cameras:

Secure Digital card (SD)

CompactFlash (CF-I and CF-II)

Memory Stick

MultiMediaCard (MMC)

SmartMedia

xD-Picture Card (xD)

USB flash drive

Software(4.4)

As digital photography increases in popularity, more and more software has become

available for the general public. The different types of software enable the user to

make changes to his/her photos using a PC.

Examples of such software include:

15


16/19

Auto FX Software, allows the user to adjust the lighting and shading within the

desired photo, thus allowing the user to create the feel and tone they wish.

BlackMagic, which allows the user to change black and white photos to colour and

vice versa.

Editing

(4.5)

The most powerful program for editing photos is Adobes Photoshop. Unfortunately,

its very expensive. The good news is that there is a less expensive version called

Photoshop Elements, which has nearly all of features of the full version is can be

downloaded for a free trial. An increasingly intriguing alternative is the The Gimp.

The Gimp is a freeware alternative to Photoshop that runs on Windows, Unix and

MacOS X. This is a complex program and the Windows version may not be

completely bug free. (1)

Benefits

(4.6)

Cost: Every film shot involves film and development costs even if you dont

print. If you use rechargeable batteries, then each unprinted digital shot is

essentially free since the cost in electricity and reduction in lifetime battery

capacity is attitude zero.

Time: If you like to share your photos through email or web based galleries, it

is easier and faster if you start with digital in the first place.

Instant gratification: You can view your results immediately.

Learning: Since you see your results immediately, you can learn from yourmistakes faster.

Size: Digital cameras are available in a wide range of form factors, some of

which can be smaller and more convenient than film cameras.

No need to change film: You can fit many times more shots on a large memory

card than you can on a large roll of film, and you dont need to change memory

cards to change ISO. (1)

Future(4.7)

16


17/19

Despite technological advances, a few negatives remain: You may make a larger initial

investment to get a digital camera instead of a film camera, and your cost per print

may be higher especially if you are printing on an inkjet printer at home. However,

this is often offset by the fact that you save money by only printing the shots that you

really want. Finally, digital can be less forgiving than film in some ways.

Report Conclusion(5.0)

Through this report, I have concluded that if your company wishes to stay ahead of the

competition, more Digital Media elements are needed. Many companies use a

combination of Audio, Video and Photography within their organization in order tohelp them expand. In conclusion of this report it is highly recommended that your

company try to expand more into the digital media community in order to evolve your

company for the coming years.
