1 Succeeding with Technology Digital Media for Work and Leisure Digital Music and Audio Digital Graphics Digital Photography and Video Interactive Media Please discontinue use of cell phone and turn off ringer Chapter 6 song I Turn My Camera On from the album Gimme Fiction by Spoon.I Turn My Camera On Gimme FictionSpoon

2 Succeeding with Technology Digital Media Digital Media encompasses digital technologies of all kinds that serve and support digital music, video, and graphics.

3 Succeeding with Technology 6.1 Digital Music and Audio Digital audio Digital music Synthesizer Sampler Sequencer MIDI Podcast Media player software Satellite Radio Key Terms

4 Succeeding with Technology Digital Audio and Music Digital audio is any type of sound, including voice, music, and sound effects, recorded and stored digitally as a series of 1s and 0s. Digital music is a subcategory of digital audio that involves recording and storing music.

5 Succeeding with Technology Digitizing Sound Example Digital Music File 10010100010010 01000100100100 10110001010101 01010010010010 10010100010010 01000100100100 10110001010101 01010010010010 30 20 10 0 -10 -20 -301020 amplitude Milliseconds (ms) 1. An analog sound wave is… -10 -20 -30 30 20 10 0 20 2. “sampled” at regular time slice, and 10 -18 -10 -20 -30 30 20 10 0 30 -10 -28 -4 20 12 -4 -10 0 2 -3 4 2 -10 -18 0 20 3. stored as a sequence of numeric values… (30,-10,-28,-4,20,…) A sound wave is sampled at predefined time intervals (sampling rate) the amplitude for each sample is stored as a binary number. The sampling rate for audio CDs is 44,100 samples per second, whereas the sampling rate of your voice on a digital cell phone is 8000 times per second.

6 Succeeding with Technology Digitizing Sound Definitions you need to know Analog to Digital Conversion (ADC)  A process where sound waves are represented with numbers or digitally converted  Also known as Sampling Digital to Analog Conversion (DAC)  A process where digitized sound is transformed back into its analog form

7 Succeeding with Technology Digital Sound For Professionals Digital Voice Recorders are used in many professions to capture dialogue for future reference. Digital audio is used in Science, Law Enforcement, Entertainment and Communications Digital audio techniques are used in speech and voice recognition. http://www.ntnu.no/gemini/2003-06e/19.htm

8 Succeeding with Technology Digital Sound For Professionals Forensic audio uses digital processing to de-noise, enhance, edit, and detect sounds to assist in criminal investigations. Abby’s lab- NCIS

9 Succeeding with Technology Digital Music & Sound Sound Production Studio Westlake Audio Studio in Hollywood, CA uses millions of dollars worth of digital audio equipment to produce music CDs, sound tracks for motion pictures, and many other audio services.

10 Succeeding with Technology Digital Music Production Tools A synthesizer electronically produces sounds designed to be similar to the sounds of real instruments; they can also produce new sounds unlike any that a traditional instrument could produce. A sampler digitally records real musical instrument sounds and allows them to be played back at various pitches using an electronic keyboard. A sequencer allows musicians to create multitrack recordings with a minimal investment in equipment. http://www.yamaha.com/musicproduction/

11 Succeeding with Technology MIDI The musical instrument digital interface (MIDI) protocol provides a standard language for digital music devices to use in communicating with each other.

15 Succeeding with Technology Digital Music Media CDs, CD-Rs, CD-RWs, Mini-disks Flash Memory Hard Drive Creative's Sound Blaster Wireless Music (listed at $250) is the first digital media receiver to offer music-file navigation via a remote control with a large LCD. The idea is that once you've configured the small, modem-size base unit to work with your Wi-Fi network, you'll be able to stream music over the system to any stereo or even a set of powered speakers. http://reviews.cnet.com/4521-6531_7-5021436-2.html?tag=dir.top

16 Succeeding with Technology Players and Software Media player software such as iTunes, Windows Media Player, and RealPlayer, and soon the latest ZUNE allows users to organize and play digital music, audio, and video files on PCs and media devices. Microsoft rolls out three new Zunes

20 Succeeding with Technology Digital Graphics Digital graphics refers to computer-based media applications that support creating, editing, and viewing 2D and 3D images and animation.

21 Succeeding with Technology Digitizing Graphics Digital images are made up of a grid of small points called pixels (short for picture element).

22 Succeeding with Technology Digitizing Graphics Colors for pixels are expressed using numbers that represent combinations of intensities of red, blue, and green, with one byte (256 levels of intensity) for each. Using three bytes provides 16,777,216 (2 24 ) possible colors. How many bits does your PC use for color? Check your display properties.
