  1. SOUND & AUDIO IN ELECTRONIC MEDIA APPLICATIONS

  2. Some Characteristics of Sound A Good Website for An Introduction to Sound Waves Amplitude or Loudness Human ear - from 1 - 120db-SPL Frequency or Pitch Human voice - 10 - 20, 000 hertz Musical instruments - 30 - 20,000 Timbre A sound’s ‘color’ and richness Microphone Impedance Levels: Ratings in Ohms Impedance Level 38 - 150 Low 600-2400 Medium 9600 & above High

  3. WHAT IS IMPEDANCE? Impedance is an electronics term which measures the amount of opposition a device has to an AC current (such as an audio signal). Technically speaking, it is the combined effect of capacitance, inductance, and resistance on a signal. LOW impedance is better than HIGH impedance. Low is usually associated with Professional Mics,High, with amateur Mics

  4. Some Mic Characteristics RECORDING ELEMENTS 1. Ribbon - delicate, rich sound, generally for studio. 2. Moving Coil/Dynamic - sturdy, multiple sizes, shapes & applications. 3. Condenser - charge plate; needs a power source; reliable and varied applications Pickup Patterns (Directionality) 1. Omni 2. Bi- 3. Uni- a) cardioid b) hyper cardioid c) super cardioid

  5. MORE CHARACTERISTICS MIC CONNECTORS Professional - XLR (grounded): Amateur - RCA (Ungrounded) Female XLR Male XLR Male & Female RCA Connectors Mini Plug Connector

  6. Typical analog VU (Volume Unit) Meter

  7. Typical 2 - Channel LED Audio Meter

  8. Guidelines for Audio Recording • Do not use on Auto unless absolutely necessary • Don’t let the audio signal over modulate, especially in digital formats • Always use head sets for monitoring audio, then: • Listen for location noises: air conditioners, planes, background talk, electrical hums, etc. STOP THE RECORDING/TAKE if you encounter any of the above. Take appropriate action to correct the problem if at all possible.. • Don’t let an audio (XLR cord) run parallel to an Extension Cord.
