Film/Television Sound Recordist , 8. Field Sound Engineer, 9.Audio Editor, 10. Post-Production Audio Creator .
5. List three careers that need to have an understanding of audio production concepts1. Music Producer, 2. Audio editor, 3. Film/Television Sound Recordist6. A person rings a bell and another person hears the sound. Draw a diagram (in your composition book) of how this sound is created, transmitted, and received by a human7. What is a waveforma wave traveling along a path from left to right, but real sound waves travel in an expanding sphere from the source.8. Is sound two dimensional or three dimensional?two dimensional9. How do variations in sound pressure correlate to a waveform diagram?a way of looking at how sound waves work and how they are represented as a waveform10. Illustrate (in your composition book) the difference between wavelength, amplitude, and frequency.11. Diagram (in your composition book) in phase, 180deg out of phase, and different wave and how they interact.12. Define transducerA device which converts energy from one form into another.13. Define amplifierA device which takes a signal and increases it's power (i.e. it increases the amplitude).14. Define signal processordevices and software which allow the manipulation of the signal in various ways. The most common processors are tonal adjusters such as bass and treble controls.15. Diagram (in your composition book) the 3 part model as described in the article.
