  3. 3. Audio Applications <ul><li>Sound Versus Audio </li></ul><ul><ul><li>Sound is a form of energy, just like electricity and light. Sound is made when air molecules vibrate and move in a pattern called waves, or sound waves. </li></ul></ul><ul><ul><li>Audio can be defined as any sound in a form of digital like voice, music, narration and others that can be heard. </li></ul></ul>
  4. 4. Audio Applications <ul><li>Audio Definitions </li></ul><ul><ul><li>A popular form of sound used in multimedia is called sampled sound or digital audio. </li></ul></ul><ul><ul><li>Hi-Fi, stereo, digital audio, CD-ROM quality – terms relative to sound. </li></ul></ul>
  5. 5. Audio Applications <ul><li>Audio Definitions </li></ul><ul><ul><li>Digital audio data are the actual representations of sound, stored in the form of thousands of individual numbers (called samples). </li></ul></ul><ul><ul><li>The digital data represent the instantaneous amplitude (or loudness) of a sound at discrete slices of time. </li></ul></ul>
  6. 6. Audio Applications <ul><li>Sound has been a vital element in our lives. We invented words to communicate with each other. </li></ul><ul><li>Babies make up their own sounds when they want t o tell you something. </li></ul><ul><li>Today sounds has become so integral in our day-to-day functions – appliances like the TV, radio, CD player and even our car alarms and hand phones are examples of technologies that can play sound or have sound added to them. </li></ul>
  7. 7. Audio Applications <ul><li>Sound has become a crucial element in our efforts to communicate our messages to one another. </li></ul><ul><li>Moving towards integrating the sound media in our applications only serves to make our presentations truly multimedia. </li></ul>
  8. 8. Audio Applications <ul><li>It captures attention. In a kiosk presentation in a trade show, for example, the sound will draw a passerby to your station, as it complements the graphics on the screen. </li></ul><ul><li>It increases the associations the end-user makes with the information in their minds. </li></ul><ul><li>An end-user is more likely to remember what he/she saw on the screen if he/she can associate it with the music he/she heard. </li></ul>
  9. 9. Audio Applications <ul><li>Sound adds an exciting dimension to an otherwise flat presentation. </li></ul><ul><li>It stimulates our aural senses, heightens our awareness to the other elements at play in the presentation, thus receiving the message sent in an enjoyable manner. </li></ul>
  10. 10. Audio for Video & Film <ul><li>In recent years, audio become more important part of video, film and broadcast production. </li></ul><ul><li>With the introduced of multichannel television sound (MTS) and surround sound - audio has grown to being a highly respected part of film and video media production. </li></ul>
  11. 11. Audio for Video & Film <ul><li>The public has come to expect higher level in audio production quality due to the: </li></ul><ul><ul><li>common use of surround sound in the creation of movie soundtracks </li></ul></ul><ul><ul><li>the growing popularity of surround in-home entertainment systems and </li></ul></ul><ul><ul><li>an ever-growing number of playback systems for sound, visual media, and computer media . </li></ul></ul>

  18. 18. Audio for Web <ul><li>In this day of surfing and streaming media off the Web, WWW has become an important marketing tool for cost-effectively getting downloadable - songs, promotional material, touring info, and liner notes. </li></ul><ul><li>As with other media, mastering for the Internet can either be complicated, requiring professional knowledge and experience, or it can be a straightforward process that can be carried out from a desktop pc </li></ul>
  19. 19. Audio for Web <ul><li>In this iPod world of MP3s, Windows Media, desktop video, Internet radio stations, and who knows what other types of streaming media, the rule that all cyber-producers live by is bandwidth . </li></ul><ul><li>the bandwidth of a media and delivery/receiving system refers to the ability to squeeze as much data (often compressed data) through a wire, wireless, or optical pipeline in as short a time as is possible. </li></ul>
  20. 20. Audio for Web <ul><li>Transmitting the highest audio and/or video feed over a limited bandwidth will often require specialized (and often accessible) production tools. </li></ul><ul><li>The Internet works by communicating requests and data from a user’s PC to a single server that’s connected to other servers around the world, which are likewise connected to other users’ PCs. </li></ul>
  21. 21. Audio for Web <ul><li>There are many advantages to adding sound to a website such as: </li></ul><ul><ul><li>providing another dimensional aspect to the experience </li></ul></ul><ul><ul><li>creating otherwise unseen intentions to a website </li></ul></ul><ul><ul><li>adding another sensory perception to the multimedia experience. </li></ul></ul>
  22. 22. Audio for Web <ul><li>Three possible way to put sound into a web </li></ul><ul><ul><li>music - sound background </li></ul></ul><ul><ul><li>sound effects - sound of button clicked </li></ul></ul><ul><ul><li>narration - explanation about product </li></ul></ul>
  23. 23. Audio for Web <ul><li>Background Sound </li></ul><ul><ul><li>Here the audio file being played is one that will set a mood or ambience for the presentation. </li></ul></ul><ul><ul><li>Product launches will invariably have upbeat music playing to create an environment of excitement and anticipation. </li></ul></ul><ul><ul><li>Company sales presentations may have a more melodic tune in the background to give attention to the speaker supporting the presentation. And edutainment titles will play children's music, simple yet up tempo. </li></ul></ul>
  24. 24. Audio for Web <ul><li>Sound Effect </li></ul><ul><ul><li>These sounds serve to punctuate an event. Clicking on a button may trigger the sound effect &quot;Ding!&quot; so that the audience is alerted to the action. Transitions may have a sweeping sound effect </li></ul></ul><ul><ul><li>Attached to them to accentuate the changing of the screen. These effects are small in size but they are powerful in effect. </li></ul></ul>
  25. 25. Audio for Web <ul><li>Sound Effect </li></ul><ul><ul><li>Here speaker support is brought in. You may want to have built-in narration introducing your product over some background music. </li></ul></ul><ul><ul><li>These eliminates the need to have someone standing at the front talking. Narration breaks up the flow of the background music. </li></ul></ul><ul><ul><li>It is recommended that the narrations be kept to a minimum in a presentation or it can sometimes be disruptive. But if it is in a CBT (Computer-Based Training) module, narrations are integral as the training is self-directed. </li></ul></ul>
  26. 26. Audio for Web <ul><li>Tips for Web Sound Design </li></ul><ul><ul><li>pay attention to the sounds around you in your everyday life. Imagine how you would recreate them with effects. </li></ul></ul><ul><ul><li>focus on sounds that have the highest emotional impact. </li></ul></ul><ul><ul><li>use silence in your soundtrack. </li></ul></ul><ul><ul><li>the audio elements should have harmonious rhythm or pattern when played in sequence. </li></ul></ul><ul><ul><li>keep your soundtrack varied and simple. </li></ul></ul><ul><ul><li>try to orchestrate the sounds in your mix so that they use the entire frequency spectrum of bass, midrange & high-pitched tones </li></ul></ul>
  27. 27. Audio for Web <ul><li>Things to avoid: </li></ul><ul><ul><li>never embed sounds on the first page of a web site </li></ul></ul><ul><ul><li>avoid monotonous loop - keep loops attractive to the ear. </li></ul></ul><ul><ul><li>using low-resolution audio and low-quality audio. poor recording will sound even weaker on the Internet. </li></ul></ul>
  28. 28. Audio Team Production <ul><li>‘‘ One of the most satisfying things about being in the professional audio [and music] industry is that sense that you are part of a community.’’ – Frank Wells, editor, Pro Sound News </li></ul><ul><li>When you get right down to the important stuff, the recording field is built around pools of talented individuals and service industries who work together for a common goal—producing, selling, and enjoying music. </li></ul>
  29. 29. Audio Team Production <ul><li>The following sections describe but a few of the ways in which a person can be involved in this multifaceted industry. </li></ul><ul><ul><li>The artist </li></ul></ul><ul><ul><li>Studio Musicians & Arrangers </li></ul></ul><ul><ul><li>The Producer </li></ul></ul><ul><ul><li>The Engineer </li></ul></ul><ul><ul><li>Mastering </li></ul></ul><ul><ul><li>The DJ </li></ul></ul>
  30. 30. Audio Team Production <ul><li>The Artist </li></ul><ul><ul><li>The strength of a recorded performance begins and ends with the artist. </li></ul></ul><ul><ul><li>All the technology in the world is of little use without the existence of the central ingredients of human creativity, emotion, and technique. </li></ul></ul><ul><ul><li>Just as the overall sonic quality of a recording is no better than its weakest link, it’s the performer’s job to see that the foundation of all music—its inner soul—is laid out for all to experience and hear </li></ul></ul>
  31. 31. Audio Team Production <ul><li>Studio Musicians and Arrangers </li></ul><ul><ul><li>A project often requires additional musicians to add extra spice and depth to the artist’s recorded performance. For example: </li></ul></ul><ul><ul><ul><li>A member of a group might not be available or might not be up to the overall musical standards that are required by the project. </li></ul></ul></ul><ul><ul><ul><li>An entire group of studio musicians might be called on to provide the best possible musical support for a high-profile artist or vocalist. </li></ul></ul></ul><ul><ul><ul><li>A project might require musical ensembles (such as a choir,string section,or background vocals) for a particular part or to give a piece a fuller sound. </li></ul></ul></ul><ul><ul><ul><li>If a large ensemble is required, it might be necessary to call in a professional music contractor to coordinate all the musicians and make the financial arrangements. The project might also require a music arranger, who can notate and possibly conduct the various musical parts. </li></ul></ul></ul>
  32. 32. Audio Team Production <ul><li>The Producer </li></ul><ul><ul><li>help the artist and record company create the best possible recorded performance and final product that reflect the artist’s vision. </li></ul></ul><ul><ul><li>a producer acts collaboratively with an artist / group to guide them through the recording process. </li></ul></ul><ul><ul><li>This type of producer will often: </li></ul></ul><ul><ul><ul><li>Assist in the selection of songs </li></ul></ul></ul><ul><ul><ul><li>Help to focus the artistic goals and performance that best conveys the music to the targeted audience </li></ul></ul></ul><ul><ul><ul><li>Help to translate that performance into a final, salable product (with the technical and artistic help of an engineer and mastering engineer) </li></ul></ul></ul><ul><ul><ul><li>to understand the process of creating a final recorded project from several perspectives: business, musical performance, creative insight, and mastery of the recording process </li></ul></ul></ul>
  33. 33. Audio Team Production <ul><li>The Engineer </li></ul><ul><ul><li>can best be described as an interpreter in a techno-artistic field. </li></ul></ul><ul><ul><li>must be able to express the artist’s music and the producer’s concepts through the medium of recording technology. </li></ul></ul><ul><ul><li>During a recording session, one or more engineers can be used on a project to: </li></ul></ul><ul><ul><ul><li>Place the musicians in the desired studio positions. </li></ul></ul></ul><ul><ul><ul><li>Choose and place the microphones. </li></ul></ul></ul><ul><ul><ul><li>Set levels and balances on the recording console or DAW mixing interface. </li></ul></ul></ul><ul><ul><ul><li>Record the performance onto tape or disk. </li></ul></ul></ul><ul><ul><ul><li>Overdub additional musical parts into the session that might be needed at a later time. </li></ul></ul></ul><ul><ul><ul><li>Mix the project into a final master recording in any number of media and mono, stereo, and/or surround-sound formats. </li></ul></ul></ul>
  34. 34. Audio Team Production <ul><li>Mastering </li></ul><ul><ul><li>It’s not uncommon to have to tweak a final master recording in terms of overall and relative level, equalization (EQ), and volume dynamics so as to present the final ‘‘master’’ recording in the best possible sonic and marketable light. </li></ul></ul><ul><ul><li>This job falls to a mastering engineer, who will listen to and process the recording (often but not always in the digital domain) in a specialized, fine-tuned monitoring environment. </li></ul></ul>
  35. 35. Audio Team Production <ul><li>The DJ </li></ul><ul><ul><li>Let’s not forget one of the more important links for getting the musical word out to the buying public: the disc jockey (DJ). Actually, the role of disc jockey can take many modern-day forms: </li></ul></ul><ul><ul><ul><li>On the air —The DJ of the airwaves is still a very powerful voice for getting the word out about a particular musical product. </li></ul></ul></ul><ul><ul><ul><li>On the floor—This DJ form often reinforces the messages from the airwaves or helps to promote the musical word in a counter-cultural environment. </li></ul></ul></ul><ul><ul><ul><li>On the Web—Probably one of the more up-n-coming voices for getting the promotional word out to a large number of specially targeted audiences (both in the mainstream and in specific counter-cultures). </li></ul></ul></ul>
  36. 36. CAREER DEVELOPMENT <ul><li>there are a lot of people who are waiting in line to get into what is perceived by many to be a glamorous biz. </li></ul><ul><li>So, how do you get to the front of the line? Well, folks, here’s the key... </li></ul><ul><ul><li>A ton of self-motivation </li></ul></ul><ul><ul><li>Good networking skills </li></ul></ul><ul><li>Here are a few tips on how to get started: </li></ul><ul><ul><li>Choose a mentor (sometimes they fall out of the sky, sometimes you have to develop the relationship). </li></ul></ul><ul><ul><li>Contact companies in your area that might be looking for interns. </li></ul></ul><ul><ul><li>Use your school counselors for intern placement. </li></ul></ul><ul><ul><li>Pick the areas you want to live in (if that is a factor). </li></ul></ul><ul><ul><li>Pick the companies you are interested in. </li></ul></ul><ul><ul><li>Target these areas and companies. </li></ul></ul><ul><ul><li>Visit or send resumes to companies or studios that interest you. </li></ul></ul><ul><ul><li>Send out lots of resumes. </li></ul></ul><ul><ul><li>Follow up with a phone call. </li></ul></ul><ul><ul><li>Visit these companies just to hang out and see what they are like. </li></ul></ul><ul><ul><li>Follow up with another phone call. </li></ul></ul>
