Audio Questions
1.What is the difference between digital and analog sound production?
As a technology, analog is the precess of taking an audio signal and translating it into electronic pulses. Digital, on the other hand, is breaking the signal into a binary format where the audio of video data is represented by a series of 1's and 0's. Digital sound production is the method most used today. Weather in music, tv or movies. Ex: mp3's
2. List at least four commonly used file formats for digital sound. Distinguish between two of your selected formats.
-Mp3
-WMA
-WAV
-DivX
Mp3 and WAV are the two formats that are easiest to distinguish between. A WAV is the very basic sound format, or rather its "raw" format. These files are often very large in size, and sometimes lacking quality. Mp3's, on the other hand, are very compact in size (for everyday use for things such as hand-held mp3 players) and usually have very good quality.
3. Describe two different audio communications systems.
Two good examples of audio communications systems are the Telephone and Radio. Radio is the more basic audio communication system. It is used for communication and entertainment and is used in many places. The telephone is also a common audio communication system, which is a little more popular than the radio currently. This is not used as much for entertainment, but rather an easy means of communication with anyone anywhere in the world by just the touch of a few buttons.
4. How does sound and audio fit the communications system model?
The communications system model is very complex. It contains every known way of communication, such as writing, speaking, body language, and so on. More specifically, the communications system model contains important audio sections, containing things such as the telephone, radio, music and television. These are all things that have a major impact on our daily lives, and are a very important part of the communications system model.
