P. 254 Review and discuss

1.       Analog audio is recorded by sound waves that are stored in a way where it can be interpreted by a computer. Analog video is recorded using stills that are displayed rapidly 30 times per second to give the visual of motion in a way that the human eye can see.

2.       Sample rate is how often the camera is recording an image in a video. Sample size is the size that should be created when the video is recorded.

3.       Sound cards are important for stereo sound systems with multiple speakers so that certain parts of audio are sent to the correct location to produce more immersive sound.

4.       WAV is a file format for audio that is used by many applications. WMA is the file type created by windows media player and is used within that application and probably many others. WMA would produce a higher quality audio.

5.       When using speakers or headphones the volume should be limited because too loud of audio can damage a personís hearing either immediately or slowly over time.

6.       Plug in the microphone, hit record on the audio recording software, talk into the microphone, hit stop when finished recording. And thatís it.

7.       Audio can be edited in many applications including video editing software but the most control comes in applications that are designed to edit audio individually.

8.       Ripping process just takes audio off a CD in its digital format. MIDI is when capturing audio through a microphone.

9.       A lapel microphone can be added near the source of the audio and appear nearly invisible where the viewer probably wont even notice it and provide very high-quality audio. Mounted microphones are better for capturing audio in a larger area like as in a room or outside.

10.   The codec for speech audio should be used for speech to provide a better quality audio since voices alone are a lot different from music audio which is constantly being produced.
