Week 6: Muddy

This week was about all things multimedia; including audio, images and video.

After completing this section, we were suppose to be able to succesfully do the following:

Explain how image, audio and video data are represented on a computer system

Explain the difference between a standard video and a screencast and identify appropriate usage scenarios for each

Describe the difference between lossy vs lossless multimedia compression as applied to image, audio and video data; select the appropriate type of encryption in particular usage scenarios

Identify the most frequently used file types for each of the above types of multimedia data - type of multimedia data stored, and the key attributes of that storage type

Explain how to create new image, audio or video content

However, I was still muddy on audio files. In doing research, I found some information on audio files that made things a little clearer. I found that the Audio Files category includes compressed and uncompressed audio formats, which contain waveform data that can be played with audio playback software. This category also includes MIDI files, musical scores, and audio project files, which typically do not contain audio data.

I think that this information is useful to know and will help anyone in their quest to have a greater understanding of audio files.
