  1. Telecommunications 1 Audio Production

  2. Telecommunications 1 Audio Production Questions Have you noticed audio? What’s your background? What are some terms?

  3. Telecommunications 1 Audio Production Why is it important?

  4. Telecommunications 1 Why is Audio Production important? • Supplements the video presentation (adds detail to overall presentation) • Highlights important dialogue, sound effects, ambiancewhile filtering out unnecessary noise (Traffic, Crowds, Wind, etc.)

  5. Telecommunications 1 Listen What do you hear?

  6. Telecommunications 1 Ambience • Organic noise occurring naturally in a setting

  7. Telecommunications 1 Ambience How do we filter ambience?

  8. Telecommunications 1 Microphone Audio Production

  9. Telecommunications 1 Audio Production • Microphone (Mic) -Apparatus used to pickup sound and transform it into electric audio signal. • Pickup Pattern -The zone within which a microphone hears sound • Polar Pattern -Two dimensional representation of a mic’s pickup pattern

  10. Telecommunications 1 Pickup Pattern Audio Production Picks Up Sound from All Sides Picks Up Sound from All Sides

  11. Audio Production Polar Pattern

  12. Telecommunications 1 Microphone Types • Omnidirectional -Picks up sound equally well from ALL directions -Multi-directional • Unidirectional -Picks up sound from the FRONT of the mic -One direction • Cardioid -Another name for a unidirectional mic -Gets its name from the HEART-SHAPED pickup pattern

  13. Microphone Types Omnidirectional Microphone Picks Up Sound from All Sides Picks Up Sound from All Sides

  14. Picks Up Sound From Only The Front Unidirectional

  15. Picks Up Sound from Only the Front Cardioid Heart-Shaped Pickup Pattern

  16. Microphone Types • Hypercardioid, Supercardioid, and Ultracardioid -Have a long pickup pattern -Can pick up sounds from far away and transmit them as if they’re up-close -Heart-shape pickup pattern is widened to that of a watermelon • Shotgun Mic -Gets its name from the long physical shape of the microphone

  17. Hypercardioid Watermelon-Shaped Pickup Pattern Picks Up Sound from Only the Front

  18. Telecommunications 1 Shotgun Microphone Audio Production

  19. -Uses a small coil that moves within a magnetic field when activated by sound -Most rugged/durable -Can be used around loud noises and won’t distort • Dynamic • Condenser -Uses a movable plate that oscillates against a fixed plate to produce an audio signal -More sensitive/better quality -Requires a power supply to operate oscillating plate • Ribbon -Extremely sensitive/loud noises cause permanent damage -Usually found in recording studios

  20. Audio Production Dynamic Microphone

  21. Audio Production Condenser Microphone

  22. Audio Production Condenser Microphone

  23. Audio Production Ribbon Microphone

  24. Audio Production Ribbon Microphone

  25. Microphone Types • Hand Mics -Held in hand by Talent -Allows for greater sound control -ADVANTAGES: Need only one mic; Talent controls sound variance by moving mic closer or farther away -DISADVANTAGES: Inexperienced Talent pointing mic in the wrong directions; Talent NOT hands-free; have to pull a cable along with you (If it’s not wireless)

  26. Microphone Types Hand Mic

  27. Microphone Types -Hypercardioid mics attached to a long rod which is then suspended over Talent, out of shot -Boom operator moves the microphone as close or as far away from the Talent as they like without placing the boom in shot -ADVANTAGES: Talent doesn’t have to worry about mic placement at all; COMPLETELY hands-free -DISADVANTAGES: Must light shot so that boom shadow is not seen; Talent can potentially move out of range • Boom Mics

  28. Microphone Types Boom Microphone

  29. Audio Production Boom Operator

  30. Microphone Types -Small, rugged, omnidirectional mic used primarily for voice pickup -Usually clipped onto clothing (jacket lapel, shirt collar) 6-8 inches below the chin -ADVANTAGES: Talent is hands-free; distance from mic to Talent never changes; needs no special lighting considerations; excellent mobility -DISADVANTAGES: Picks up ambient noise; need one mic per subject; picks up rubbing noises if the talent moves; muffled sound if concealed under clothes • Lavaliere

  31. Microphone Types Lavaliere Microphone

  32. Microphone Types Wireless Lav Microphone

  41. Audio Terminology Microphone Apparatus that converts sound to electric signal Pickup Pattern Where a microphone picks up sound Polar Pattern 2-dimensional representation of pickup pattern Omnidirectional From all directions; multi-directional Unidirectional From one direction Cardioid Heart-shaped pickup pattern of unidirectional mic

  42. Audio Terminology Dyamic Rugged, dependable mic; filters out loud noised Condenser Sensitive mic, better sound pickup; requires phantom power Ribbon Extremely great sound pickup; extremely sensitive; harsh sound can destroy it Hand Mic Held by talent; allows for better sound control Lavaliere Hands-free mic; requires one mic per subject Boom Mic Held by off-camera grip; hands-free; can be in-shot

  43. Connection Types • XLR Connection -3-pin connection; professional standard -Relatively immune to outside frequencies/interference Remember: 3 pins = 3 letters

  44. XLR Connection

  45. XLR Connection 3 Pins

  46. Connection Types -1/4 “ connection -Common with consumer microphones -Usually used for instruments (e.g. guitars) • Phone Plug Also called a “quarter inch” plug

  47. Phone/1/4” Plug

  48. XLR – ¼” Connection

  49. Connection Types -Extremely common -Usually used for monitor input/output -Stereo audio (Right and Left channels) • RCA Connection Red = Right White = Left

  50. RCA Plugs
