Lab Assignment Preparation

As you work, record the time it takes you to complete this section of the lab.

Incorporate sound files into a web site 

Publish a new web page, lab330-7.htm, which contains the following items/sections (this new page will be handed-in and graded for this lab). Be sure to label all sound file/video file links with information on the file type and the file size. 

To perform many of the task below, you can manually edit the HTML file. Alternately, if you know how to use a WYSIWYG HTML editor to perform the following tasks, feel free to do so.

  • add a background sound file (.mid/.midi format) as described on page 340 of Niederst; be sure to include the file so it plays in both Netscape and Internet Explorer

  •  
  • add a simple link to the .wav-format sound file you downloaded above as described on page 338 of Niederst; also add a simple link to the manipulated .wav-format sound file you created when completing Manipulate a .WAV sound file; clearly mark the original and modified files

  •  
  • add the .au-format sound file you downloaded above to the web page using the <EMBED> tag as described on page 338 of Niederst

  •  
  • create an audio file credits section which includes the addresses of the sites from which you copied sound files. Briefly explain why it is important to select your sounds from sites that grant permission for re-use. 

  •  
  • add a simple link to the .mov-format video file you downloaded above as described on page 355 of Niederst

  •  
  • create a video file credits section which includes the address of the site from which you copied the video file. 

  •  
  • student comments section - In this section, list 3 things that you learned about working with audio files and 3 things you learned about working with video files from this lab. Also briely explain the importance/benefits of including format labels and file sizes when adding sounds or videos to a web page. Next include information on how long it took you to complete each section of this lab and now long it took you to complete the total lab. Finally include any any suggestions you have on how to improve the learning experience of this lab.
